No other fixture spreads itself more completely across your building – which means isolating vibration is a critical element in running a quiet, efficient HVAC system.

Rooftop HVAC System

Whatever the application, vibration is always going to be – at the very least – an irritant. But in an HVAC system, each vibration has the potential to travel and amplify along potentially miles of ducting. Not only does that make any vibration more of a problem – it also makes it harder to track the source.

   > Discover more about Vibration isolation for HVAC applications

So if you’re installing an HVAC system, you’ll have a number of vibration isolation elements to consider, including:

Isolating equipment: Although vibration can come from virtually any source within the system – from a loose grille to an ill-fitting section of ducting – it’s the equipment at the end of those pipes and ducts that is the most likely source.

The combination of motors and fans can create forces in multiple axes so it’s important to choose mounts and bushes that can cope with the respective forces that the system employs. Our cab/cone mounts enable isolation of all reciprocating and rotating equipment (i.e. the central plant and air handling units) from bases, supporting frames etc.

To explore which is the right isolation mount for your specific application, please contact us.

Maintenance: Ensure ducts are regularly checked for obstructions which can reduce the efficiency of the system and increase noise and vibration. Ensure regular checks of rubber mounts to identify early signs of wear or degradation.

Duct design: Duct design is critical in reducing noise and vibration. The easier it is for air to flow freely by, for example, limiting angles, bottlenecks and branches, or even avoiding the use of flexible ducting, the lower the turbulence and the lower the risk of noise and vibration generated by duct fittings and dampers.

It also means that the unit isn’t having to work too hard in supplying the required airflow requirements for the premises.

   > Discover more about Vibration isolation for HVAC applications

Installation: The way that ducting is installed also contributes to the passing of transient vibration and noise. If the ducting is simply resting on a joist, then vibration generated by the airflow can pass into the joist and through to the ceiling, causing nuisance noise.

If at all possible, the ducting should be suspended so that it cannot pass any vibration onto adjacent parts of the building fabric or structure.

Adding a silencer between the ducting and the unit should also reduce transient noise and vibration significantly.

Fan efficiency: Use a fan appropriate to the system. An undersized or oversized fan that operates outside its peak efficiency is likely to increase the risk of vibration and noise.

Vibration. Noise. Banging. It could be a sign your car’s engine mounts need replacing, but how do you know?

We’ve explored before the effects of engine mount wear and the signs that show your car’s mounts may need replacing, but the signs of mount degradation are often easy to confuse with other problems. Engine mounts aren’t the only source of vibration in a car – a crumbled wheel bearing will create a similar issue. And there are other mounts, bushes and buffers in the car which – from dashboard to transmission – can also create noise and vibration as they degrade.

   > Are you looking to replace an existing mount?

So how can you narrow the causes down to the engine mounts? The following options should help. Some of these require two people, and if you are in any doubt about your ability to perform any of the below checks, talk to a qualified mechanic.

  1. With one foot kept on the brake, press the accelerator. Engine movement of more than 25mm may indicate an engine mount problem.
  2. Depending on the model of vehicle, it may be possible to spot significant engine movement by looking for scuff marks on the underside of the bonnet or within the engine bay. If a mount wears significantly, the resulting movement could be enough to either scuff or mark the surrounding area.
  3. Place a solid block of wood on a floor jack and position beneath the sump. Raise the car a little at a time with the engine idling. If the vibration continues once the tyres are off the ground, it’s an indication that the vibration isn’t tracking from damaged suspension, faulty wheel bearings etc – and it’s likely to be one or more engine mounts.

Engine mount the problem but no sign of degradation?

If any or all of the above lead you to the conclusion that at least one engine mount is the problem, you might expect that mount to show some signs of degradation. But what if every mount looks to be in good condition?

   > View our range of engine mounts

In such situations look for an ‘odd one out’ – that is, a mount that, whilst it appears to be in good condition, is clearly a different brand or composition compared with the others.

If a replacement mount doesn’t have the correct vibration isolation capabilities for the application it could cause just as much, if not more, vibration as a faulty mount. A mount which, for example, employs too hard a rubber can leave the engine feeling as though it’s been bolted directly to the chassis.

To avoid such problems, and to ensure any replacement vibration isolation mounts you choose are the right ones, try our engine mount selector or talk to us.

Man Looking at Car Engine With Bonnet Up

Fibet engine, cab mounts and suspension bushes are trusted by manufacturers across the UK for their failsafe functionality? But what does failsafe mean in the context of an anti-vibration mount?

One of the key differentiators between our vibration isolation components is failsafe functionality. Some of our products have it (our engine mounts, cab/cone mounts and suspension bushes for example); some don’t (e.g. our bobbin mounts).

Why do some products have failsafe functionality when others don’t? And what does failsafe mean?

What is a failsafe mount?

A failsafe mount is one that will typically need to withstand compression, shear, conical and torsional forces, isolating vibration in multiple axes – even where loading is different in each direction. Such forces will be exerted in demanding, safety-critical applications.

From automotive to aircraft, unless a mount stays securely in place even if the mount fails, it presents a risk to the vehicle, its occupants and passers-by.

So, in addition to its ability to withstand the abuse of high load conditions, a failsafe mount will be constructed in a way that protects its integrity and ensures part A won’t separate from part B in the event of a crash or mount degradation.

   > View our range of engine mounts

The effect of a failsafe mount

Years ago, in the days before failsafe mounts and bushes, it wasn’t uncommon to find suspension wishbones piercing a vehicle cabin (and the occupant) in the event of an accident. That could only happen because the wishbone bushings failed and, crucially, separated from the chassis. A failed engine mount could leave the engine free to ‘bounce’ around, critically impairing stability and increasing the risk of fire or crash.

Failsafe functionality is critical in enabling vehicles to achieve 5-star Euro NCAP ratings, and to ensuring similar levels of safety in pumps, gensets, compressors and more.

How does a failsafe mount work?

The key to a failsafe mount is its assembly. Between the rubber components are – depending on the specific mount or bush – shaped and profiled washers; wires moulded into the rubber; or through-bolts which ensure that even if the mount fails, the components mounted on it remain secure and in place. You’ll notice an increase in vibration, but you (thankfully) won’t experience anything more critical. Failsafe equates to protection – and should a mount fail, failsafe functionality means you’ll simply need to change the mount rather than anything more dramatic.

   > View our range of anti vibration mounts & products

Why aren’t all vibration isolation components failsafe?

Put simply, they don’t need to be. Not every application of our buffers, stops and mounts is safety critical. Failsafes inevitably increase the cost of a component, so where there is no risk – where, for example, buffers act as rubber feet for a low vibration appliance or as shock absorbers for a cash till or computer cabinet – then a non-failsafe low cost option may be appropriate.

We should note, however, that if safety is in any way a consideration, a failsafe mount would always be the wiser option.

Failsafe Green Sign

Our bobbin mounts are used in a vast range of applications but why use them?

The Fibet range of bobbin mounts is arguably the largest in the UK. Available with male, female or combination threads and in a wide range of sizes, stiffnesses and load capacities, there are literally thousands of alternatives to choose from.

Yet bobbin mounts don’t have the failsafe functionality of cabin or engine mounts, so why would you choose them in preference to vibration isolation mounts that do?

Right mount, right application

Even in demanding, safety critical applications, not every mount may need to offer failsafe functionality. In the automotive industry, for example, failsafe mounts are essential around the engine, suspension or on transmissions. Resultantly, the mounts are designed with a failsafe functionality integral within the design or assembly of them, to assure there are no risks to the vehicle’s occupants or passers-by. But does the same apply to vibration isolation measures behind the dashboard?

There are similar instances in every industry where vibration isolation and safety don’t always need to work hand in hand. Take cash registers, checkout tills and computer cabinets, for example: bobbin mounts may play a crucial role in reducing shock and vibration every time the doors or drawers slide shut, but reliability, durability and cost are likely to be greater concerns than safety.

   > View our range of rubber bobbin mounts

Even in applications where safety is generally the number one consideration – in gensets and air compressors, marine and military applications – there may be specific instances where a failsafe mount isn’t necessary. For all these applications, bobbin mounts can be the ideal low cost alternative.

It’s important to stress that where there is any element of doubt over the need for a failsafe mount, a failsafe should be the default option.

Low cost

Every Fibet mount represents exceptional value, but bobbin mounts are the lowest cost anti-vibration mount, where the application doesn’t require a failsafe.

Elastomer range

Natural rubber is the standard elastomer of choice for Fibet mounts but depending on the environment in which the mount will be required to operate, an alternative elastomer such as neoprene, nitrile or EPDM may offer greater protection against heat, oils or chemicals. Talk to us about the right elastomer for your bobbin mounts.

Load

Choosing a bobbin mount over an alternative doesn’t mean settling for an anti-vibration mount with any lesser load capacity. Choose mounts offering 2kg-1,000kg load per unit.

Would a bobbin mount be the right low cost choice for your application? Or do you need failsafe functionality? To make the right choice, talk to us now on 01282 878200 or contact us.

What sources of vibration can cause problems for sensitive equipment – and what can you do about isolating that vibration?

Roof Top HVAC System

Vibration is the nemesis of sensitive instruments. Even a slight vibration can be enough to render a reading inaccurate or send operation outside of acceptable tolerances. Removing vibration is hard enough in land-based applications like lasers, semi-conductor fabricators or scanning tunnelling microscopes. It’s more challenging still in marine applications.

The solution lies in dampening or isolating vibration sufficiently to either eliminate it or render it insignificant in terms of the instrumentation. When talking about extremely sensitive measuring equipment, the two are frequently the same thing.

Sources of vibration

Adding to the challenge is the fact that sources of vibration are so abundant. Within the immediate vicinity, anything with a motor – a centrifuge, a fume cabinet etc – can generate vibration which can easily transmit to the neighbouring equipment or along work surfaces to equipment at the other end of the room.

Beyond the lab or clean room, the building is a rich source of vibration generated via the HVAC system, the lift and more. And even outside the building, construction work, traffic and subway systems and can all help make it harder to deliver vibration free instrumentation.

   > Discover what we can offer for your particular market sector

How to control vibration

Step 1: Understand the level of vibration isolation required. What are the acceptable tolerances, and are those tolerances likely to become even more stringent in the future? Only by understanding the preferred state of vibration within your facility can you put plans in place to achieve it.

Step 2: Identify unacceptable sources of vibration. A simple source-path-receiver model, commonly applied when identifying sound issues, should help you understand the nature of the vibrations affecting your instrumentation and take steps to inhibit them. You can do this by:

  • Controlling the vibration at source – for example by applying a vibration isolating mount to a motor frame
  • Changing or blocking the path vibrations use to travel from source to your instrumentation – most simply achieved by increasing the distance between source and instrumentation; or
  • Isolate vibration at the instrumentation – typically by using buffers, stops and mounts which can attenuate vibrations transmitting to the instrumentation

Many of the market leading anti-vibration mounts and bushes supplied by Fibet incorporate natural rubber. But where does natural rubber come from, and what are its advantages over synthetic alternatives?

Coagulated Lump of Raw Natural Rubber

It’s not just the ability to absorb vibration that makes natural rubber an ideal material to use in vibration isolation. It’s the rubber’s tensile strength, tear resistance and the ability to withstand deformity – that is, to return to its original shape again and again – that makes it a logical choice for demanding applications ranging from automotive to marine to agriculture.

   > Find more about what makes natural rubber an anti-vibration material

Where does natural rubber come from?

Natural rubber is made from the latex that oozes from certain plants when cut. Snap a dandelion in two, for example, and you’ll see latex oozing from the stem. Although latex is found in around 200 species of plant and tree, around 99% of the world’s natural rubber comes from just one: the Hevea brasiliensis (or rubber) tree.

In its latex form the milky substance is primarily water, with rubber particles suspended within it. Once refined and vulcanised into coagulated lumps, however, the natural rubber can be processed into a huge range of products, including Fibet vibration isolation components.

Natural vs synthetic

By their nature, synthetic rubbers are manufactured for specific purposes and are highly effective when applied to their intended applications. Neoprene, for example, is more resistant to oil and chemicals than natural rubber, and is therefore the optimal choice for mechanical seals, laboratory hosing and plumbing fixtures.

Natural rubber, however, remains the ‘go-to’ rubber for around 40% of the world rubber market because of typical characteristics that include:

  • High tensile strength
  • Tear and abrasion resistance
  • Ease of processing
  • Dynamic performance
  • Good low-temperature properties
  • Low heat build-up
  • Ease of bonding to metal parts

It is for this reason that natural rubber remains the natural choice for rubber gaskets, electrical components, hoses and tubes, drive couplings and anti-vibration mounts and buffers.

Our anti-vibration components are no stranger to automotive or military applications. But recently, we were challenged to develop an anti-vibration mount for a tank of a different kind – one that fires paintballs.

If your idea of paintballing is something that happens on foot, then it’s probably time you climbed back into the camouflage gear and strapped on the face mask, because paintballing has changed. Today, paintballing isn’t just about hiding in a bush and waiting for an unlucky enemy to wander into your line of sight. Now, you can charge the enemy in your own paint-firing armoured vehicle.

Paintball Battle Tanks has taken real world vehicles like the Scorpion Tank, the Willy’s Jeep and the Armadillo, miniaturised them and turned them into paintballing combat vehicles – but as with their full size counterparts, isolating vibration is a key issue.

All terrain anti-vibration

It’s important that every vehicle gives drivers a fun ride. Here, that means ensuring engines are mounted in a way that doesn’t cause vibration that detracts from the enjoyment of the experience (not to mention compromising shooting accuracy). And this being paintball, eliminating that vibration is made all the more challenging by the all-terrain nature of the combat.

We explored a number of mount options for the vehicles before recommending a cone mount which would allow the engine to move in all directions safely (axially, radially and conically) without any risk of it separating from the chassis.

The mounts also offer a fail-safe solution when installed with the supplied washers, but the existing assembly would require some modification to accommodate them.

Tailoring the solution

We partnered with the client to explore installation methods and settled on a modification which would require shifting the position of securing holes and the centre hole. The centre hole would also need to be chamfered to accept the mount.

With all modifications completed swiftly at our Italian HQ, the parts are now in place on the paintball tanks and are helping to ensure that paintballing remains a high octane but low vibration experience.

Each of our buffers, bushes and mounts use rubber to isolate vibration. But what is it about rubber that makes it ideal for the job?

Whether it’s an engine, a motor, a pump or a generating set – whatever your equipment is designed to do, there’s an inevitability that it will also generate something less welcome too: vibration.

   > What is vibration?

The rubber that is used in Fibet’s bushes, bobbins and engine mounts is excellent at isolating and reducing vibration because of its insulation capabilities and resilience. The natural insulation provided by rubber ensures that vibration is absorbed, not conducted, while resilience is seen in rubber’s ability to recover from deformity. Rubber can withstand significant deformation whilst still returning to its original shape time after time. This is essential in applications where a mount or buffer is subject to multiple and frequent stress forces (such as those found in an automotive engine).

The key to this elasticity lies in the long chains of molecules that form to create natural rubber when vulcanised (that is, when cross-linked with sulphur atoms at high temperature). At this point, the rubber’s strength and integrity is increased still further, creating the rubber that we know, and making it suitable as a vibration isolator for industrial use.

   > Discover more about our technical expertise and project management

The hardness of the rubber is critical – too soft, and there’s a risk the application’s stress forces will overwhelm the rubber’s ability to recover from deformity, damaging the mount (and the engine/pump/motor that sits on it) and reducing its effectiveness. Too hard, and there is the risk that the rubber won’t reduce the vibration, but merely pass the vibration through the mount into the adjoining components. This will result in early failure of the application.

The environment is a major consideration. Rubber is highly adept at resisting heat and water, but intense heat, pressure or vibration may require a specific composition of rubber.

The natural frequency of the mounts, bushes or bobbins also needs to be considered. If it coincides with the frequency of the equipment, the result can be resonance, which is the magnification, rather than the eradication of vibration.

Range of Anti Vibration Mounts

Engine mounts are supposed to reduce engine vibration. But choose inferior mounts, the wrong type or hardness, or fail to replace damaged ones, and you could find they are the cause of vibration and more…

Engine vibration

The first sign of engine vibration may be an unfamiliar noise. In automotive applications, you (or at least your passengers) may notice vibration through the passenger seat. A damaged engine mount reduces the mount’s capacity to isolate vibration and, as the mount deteriorates further, the problem will only worsen. Check mounts at the first sign of vibration to ensure it doesn’t have knock-on effects that damage far more than the mounts.

   > View our range of engine mounts

Increased deterioration

The bell design of our engine mounts is no accident. The shape is integral to guiding oils and lubricants away from the mount, maximising their lifespan. But when the rubber within the engine mounts begin to degrade, crack or crumble, the result is increased vibration. Check for cracks in the rubber section of the engine mounts, or any signs of severe rust or perforation within the metal components and replace before degradation increases.

   > Are you looking to replace an existing mount?

Additional damage

Damaged or poor engine mounts can lead to a range of problems. Misalignment can leave the engine incorrectly installed (risking damage to the engine block). The engine could have a tendency to move erratically which can loosen parts including belts and hoses. Such problems are likely only in engines running at high speeds and where the degradation of the engine mount is significant. However, the result can be costly damage that could have been avoided by replacing an inexpensive engine mount.

Impact noise

As engine mounts wear, the greater the risk of the infamous comment ‘did you hear that?’ Over time, the noise then starts to become an unmistakeable ‘clank’ or ‘bang’ before resulting in the failure of the mount or even worse – the engine.

In summary, inferior or damaged engine mounts can cause vibration and damage, whilst replacing your engine mounts can eradicate all the above issues.

Heavy Duty Anti Vibration Mount

And where does it come from?

Fibet manufactures and supplies anti-vibration products for a significant number of sectors including marine, automotive and agricultural. Vibration is something we all know when we hear or feel it, but what actually is it?

Vibration is the oscillation of a body around a central point, and it is those oscillations that form the basis of measurement. By counting the number of complete oscillation cycles within a second we arrive at a frequency, measured in hertz (Hz).

Vibration can be found in a single body in a state of oscillation (e.g. a tuning fork), but you are far more likely to have multiple frequencies occurring simultaneously in everyday applications. In motors, engines and any of the equipment in which you will typically find our engine buffers, mounts and bushes, it can often take detailed frequency analysis to determine which specific components are the cause of unwanted vibration.

Is all vibration bad?

Excessive vibration in many mechanical applications is rarely good news, but controlled levels of vibration are often integral to a piece of equipment’s function. Mechanical feeders, compactors, sanders, massage chairs etc they all harness vibration is some way to perform their tasks, so the components they require will need to limit and control vibration, without eliminating it entirely.

Where does vibration come from?

Vibration is a consequence of out of balance forces in the way components connect or rub together. It is entirely natural and virtually inevitable in any mechanical equipment, and often even small vibrations can resonate through other parts of the structure where the vibration can be amplified and the noise increased.

Anti-vibration bushes, mounts and buffers are the tools that prevent vibration developing across structures in a way that is irritating to the user and potentially damaging to the machine.

If eradicating vibration is proving a challenge in your application, talk to the vibration experts. Call Fibet now on 01282 878200 or email us at sales@fibet.co.uk

Here are four signs to look out for…

Engine mounts may not be the most headline-worthy part of the engine, but they perform a vital role, protecting the components (and any operators/drivers) from shocks and vibration. Fibets’ engine mounts are designed to deliver consistent and robust anti-vibration performance year after year, but over time even the best engine mounts will start to show their age. Knowing what to look for in a deteriorating engine mount can help you address issues fast, before they have time to cause wider and more significant problems. Here’s what to look out for…

1. Increased noise and vibration

When an engine mount is worn or damaged its anti-vibration properties reduce. The first sign of that is often a growing awareness of unfamiliar knocking noises, or simply more engine noise than you’re used to. Vibration isn’t an easy thing to pin down. You’re unlikely to be able to see the cause (unless a mount has degraded to such an extent that it’s obvious – see below) and because vibration travels, the source of the noise is unlikely to be easily identified. But don’t ignore an increase in noise or vibration. The longer you leave it, the greater the risk the vibrations will become stronger and potentially damage other parts of the engine.

2. Jarring gears

If changing gears at speed feels clunkier and more jolting than usual, the cause could be a worn or damaged engine mount affecting the transmission.

   > View our range of engine mounts

3. The lurch

Significant damage to an engine mount can cause the engine to feel as though it’s ‘lurching’ when you turn the ignition on or off. The feel and sound of the lurch are both easily noticeable. Whilst things may quickly settle down, you’re likely to still notice an underlying and ongoing vibration whilst the engine is in operation.

4. Visual wear

Engine mount wear is usually not immediately apparent on visual inspection, but significant wear or damage can be. Look for cracks, corrosion or crumbling rubber. As engine mounts need to retain their structural integrity to do their job, any signs that the mount is degrading are likely to coincide with reduced performance. Replace any engine mounts that appear to be damaged as soon as possible.

When replacing engine mounts, it is prudent to replace the full set – because if one engine mount has degraded, the chances are that the others will have too.

By replacing a full set of mounts, it will avoid any additional expense and time involved in having to dis-assemble the adjoining components multiple times.

Key considerations for choosing the right levelling feet.

From pumps, engines, plant and machinery to white goods, a level surface is essential to optimal performance. When products are designed to perform on the flat, levelling feet help reduce stresses and vibration, protect performance and minimise wear. But which levelling feet are right for your application? Here are some key considerations…

Load

Levelling feet can’t keep your product level if they buckle under the weight. That’s why we supply a range of heavy duty levelling feet from 80 to 200 mm diameter, with loads applied from 500 daN (approx. 510kg) to 4,000 daN (approx. 4,079kg). Such heavy duty feet are ideal for applications including engines, industrial machinery, HVAC equipment, pumps and more.

For less weighty demands, our extensive range of light duty feet should be more than robust enough for most applications.

Materials

Our levelling feet find their way into a wide range of environments, from factory floors to food and pharmaceutical production areas.

That’s why we manufacture and supply levelling feet in a similarly wide range of materials. Our oil and water resistant rubber feet have varying degrees of elastomeric hardness. And our stainless or coated steel spindles ensure every part of the feet meet your hygiene, non-marking, non-corrosive requirements.

Combinations

Our levelling feet are available in a huge variety of combinations, so you can easily tailor the load, diameter, coating and foot composition to your specific application.

Need a solution that can secure your application to the floor?

If you need to attach your equipment to the floor, take a look at our extensive range of engine mounts that can ensure nothing moves during operation.

If your floor is uneven, our range of height adjusters can be used in conjunction with our engine mounts to give you the best of all worlds.

No need for levelling?

Not every product is going to face an uneven floor. Sometimes, when a slight tilt won’t affect performance, adding levelling feet and machining threaded footplates can be an engineering step (and cost) too far. So when level isn’t essential, choose end stops as a non-adjustable way of protecting the base of products.

Take the guesswork out of choosing the right engine mount for your application – use our quick reference guide.

The typical engine mount doesn’t attract a lot of attention. It’s one of those essential elements of product design that you only really notice when it isn’t there. Yet, whether its application is automotive, general engineering, marine or agricultural, there’s no mistaking the vibration and noise caused by a missing or damaged engine mount.

To make matters trickier, a missing or damaged engine mount can leave the vibration free to travel through the frame or supporting structure until it is emitted as noise somewhere often far removed from the original source. Identifying the source of vibration is rarely easy, but checking the engine mounts is invariably a good starting point.

   > View our range of engine mounts

That said, even when you identify the engine mount as the culprit, it can often seem as though your challenges are only just beginning, because then you have to find a suitable replacement. In a sector with a near infinite choice of sizes, materials and loads, finding the right engine mount can seem like searching for a needle in a haystack.

That’s why we’ve created this quick guide

It doesn’t consider every element or load characteristic that can affect mount selection, but it should cover most circumstances and enable you to choose an engine mount that offers the right level of vibration isolation and load, whilst also meeting that most crucial of conditions i.e. it needs to fit.

Caveats

The quick guide is a handy tool for most applications. It won’t, however, lead you to the right engine mount if it is to be subjected to harsh environmental conditions. For such circumstances, or if you’re already experiencing vibration issues, we’d suggest that you talk to us before making your selection.

You can do that by calling us on 01282 878200 or emailing us at sales@fibet.co.uk

Why we’re proud to be members of the Northern Auto Alliance

The North West is a major player in the UK automotive industry. Around 300,000 vehicles roll off production lines across the region every year, accounting for about 16,000 jobs and £9 billion in sales (the second highest regional total for the UK auto sector).

Those numbers look even more impressive when you consider the vehicles involved. From the Bentley Continental at Crewe to the ‘baby’ Range Rover Evoque at Halewood, much of what the North West is producing is a long way from the mass market.

Fibet’s anti-vibration mounts, buffers and bobbins are a regular feature in many more sectors than automotive, but it was the automotive sector that was our initial focus when we launched the business in 1952. Today, our products remain a staple of the North West auto-manufacturing trade, in domestic cars and commercial vehicles.

And that’s why we’re continuing members of the Northern Automotive Alliance (NAA).

Fibet and the NAA

Fibet has been a member of the NAA for almost as long as it has been an independent, non-government-funded body. We joined in 2013 because the partnerships and collaborations it fosters very much reflect our own.

What we value about the NAA is that it isn’t a closed shop for the big players. It’s a body that works for every member of the automotive industry: from global players like Vauxhall to independent specialists like Fibet.

It’s also an association that forges links with the bodies that can influence the wider automotive world – such as universities, councils and LEPs. That’s a close match for the way we work and the way we build collaborations (as, for example, our work with the Leeds Institute of Mechanical Engineers Race Team, demonstrates).

So we’re pleased to remain an NAA member, because of the values we share, because of the visibility it gives us in the market sector in which we made our name, and because of the way it brings local companies together.

You can find out more about the NAA here. And if you’d like to explore how partnership with Fibet could benefit your automotive (or other) business, contact us now on 01282 878200 or email us at sales@fibet.co.uk

Fibet’s anti-vibration products may not have prevented Crank-E from taking a mechanical mauling, but they did an impressive job of limiting damage.

There are some things you don’t see in your average episode of Robot Wars. Usually, while Dara O’Briain and Angela Scanlon are interviewing the teams and asking what went right/wrong, there’s a team out of shot sadly shovelling what’s left of their robot into a proverbial (or literal) bin bag.

But that wasn’t (quite) the case for the Cold Fusion Team. True, their robot Crank-E may have been bested by one of the hot favourites. And insult may have been added to injury when house robot Shunt decided to let rip with its pickaxe. But Crank-E escaped with relatively little internal damage, a fact that was all down to a design incorporating Fibet rubber bobbins.

Crank-E Heavyweight Robot

The Cold Fusion Team were experienced robot builders and Robot Wars veterans. They knew all about the strict weight and size limitations imposed by the programme makers and that gave them a real challenge when constructing compliant external armour plating and the weapon sub-frame. A further challenge came from the fact that no team knows precisely what form or force of impact they’ll be facing – from buzz saws and angle grinders to picks and spikes, the potential arsenal is almost limitless.

The team’s initial solution of fail-safe design shock absorbers didn’t fit with the size requirement, so the alternative was to use many bushes in parallel to protect the chassis, motor and electronics.

“Fibet brought experience and enthusiasm to the project and were a pleasure to work with,” said the Cold Fusion Team. “If the outcome was not entirely successful, it was due to the challenging weight and spatial requirements, and the harsh operating environment. Despite the robot taking a beating from one of the top competitor robots and a house robot, the rubber bobbins protected the internals and chassis from severe damage and allowed them to be reused.”

How Fibet’s pragmatic approach to bush and engine mount selection helped the Leeds Formula Race Team get race ready.

When it comes to learning your trade, there’s no substitute for real world experience. That’s the reason for the existence of the Institute of Mechanical Engineers (IMechE) Formula Student Competition, a student-only competition held at Silverstone every year, which gives engineers the chance to put their skills and ideas into practice.

Before Leeds Formula Race Team could enter the challenge they needed a way of powering their chassis design. They had an engine (from a KTM bike). They just needed a way of mounting the engine on the F18 car chassis in a way that would prevent movement and vibration from compromising performance.

The team approached Fibet for an engine mount solution and, given that this was effectively a student project, cost was a major factor.

Despite the car being anything but a standard design, we developed a solution that enabled the team to use one of our standard products. This helped keep development costs to a minimum, as well as ensuring that parts were always available within a very short lead time.

With teams entering from around the world (from Iceland to India), competition was always going to be tough, but we were delighted to see that, of 67 teams taking part, the Leeds University team came in the top 20 for design.

We’re grateful to the team for the following newsletter mention:

“Thank you to Fibet UK Limited for help with the selection and supply of bushes for the novel engine mounting system in this year’s car.”
