More sustainability and environmental protection: Longer relubrication and oil change intervals reduce the required lubrication amounts. Using rapidly biodegradable lubricants reduces the environmental burden of railway operations.

Just a few months ago I’ve had the rear wheel bearings of my E36 replaced. When the mechanic popped them out, he said that the rear right bearing was shot beyond recognition and it was a miracle that it didn’t break.

Sustainability and environmental protection are close to our heart. Long relubrication intervals lead to reduced lubrication amounts and less used lubricants to be disposed of. Furthermore, many of our lubricants are rapidly biodegradable, making them especially friendly to the environment.

Wheel bearings play an important role within the drivetrain of any vehicle, as they provide the first connection between the moving and static areas of the car. A bearing – in its simplest form – is a friction reduction device placed within something like a wheel to aid the efficiency of rotation. This is achieved as rolling produces much less friction force than sliding.

Specialty lubricants from Klüber Lubrication for train maintenance and infrastructure prove their worth worldwide every day. They include solutions for many lubrication points in railway engineering, from lubrication of traction systems and doors to axle gears and wheel flanges, bogies, brakes, and many other components.

Our lubricants for door seals and spindle drives enable easy and reliable opening and closing, even with varying temperatures. They provide a high degree of protection against wear, as well as optimal ageing resistance  – true top-performers in the race against downtime.

Also in gearboxes, lubricant must render maximum performance for rail operators to attain their objectives: high train availability and minimum downtime due to maintenance and repair. Klüber Lubrication has therefore developed gear oils tailored to the railway industry that enable distinctly longer oil change intervals. Our gear oils have the potential to double oil change intervals, significantly reducing maintenance effort and operating costs. The resulting higher train availability can help to reduce delays and thus increase customer satisfaction. Gear oils from Klüber Lubrication are approved by worldwide leading gear unit manufacturers in the railway industry and have a proven track record in harsh everyday operation.

As long as you catch a wheel bearing issue early, though, it shouldn’t be a massively expensive or time-consuming fix, and if you’re decent with a spanner, it’s potentially something you can sort yourself. Here’s what a wheel bearing is, why it’s important, and how to tell if there’s something wrong with one.

Klüber Lubrication offers a portfolio of lubricants specifically for doors, which ensure both long relubrication intervals and high reserve capacity. All leading door manufacturers have approved lubricants from Klüber Lubrication and use them in their series production.

Like all mechanical parts on a car that rotates, rub and roll, they tend to wear out eventually. There are several signs of a knackered wheel bearing. The most common is a constant drone, hum or growl from the affected wheel, which will get more noticeable as speed increases or the car turns. You may also notice less responsive steering or speed-dependent wheel wobble. On more modern cars, which often have anti-lock brake sensors integrated into the hub assembly, you might get an ABS warning light on the dash.

With the requirement for zero-downtime operation under extremely severe environmental conditions, the railway industry places stringent demands on rail vehicles and infrastructure. With good reason: unscheduled maintenance and damage incur high costs and often have a long-term impact on punctuality. Specialty lubricants from Klüber Lubrication are developed specifically to meet these high demands. Leading manufacturers in the railway industry rely on our lubricants for railway applications. These lubricants have a proven track record under harsh conditions, are economical in use, and are easy to procure thanks to worldwide availability. In short, they offer everything you need to attain your foremost goal: more cost efficiency!

Wheel bearingreplacement cost

Although it can be a labour-intensive job if one were to fail, the shift to selling entire hub assemblies should make a bad wheel bearing fixable from home, with a decent tool kit and a bit of know-how. So do not fret the next time that horrid whir begins to creep into the cabin, as a fix may be only a ratchet spanner away.

Proven in tests and in practice: Our specialty lubricants are developed in close cooperation with the railway industry and extensively tested. Numerous leading manufacturers have issued corresponding approvals and rely on our lubricants.

As a partner to the industry, we work in close cooperation with manufacturers, maintenance specialists and operators to constantly develop new, optimised lubricants for the rail industry that meet special requirements. Top-notch performance can only be attained by pulling together.

Which means, that a few months prior, I’ve just hit 210 KPH with broken wheel bearings in what’s essentially a 20 years old coffin on wheels. Yay.

Wheel bearings are generally made from hardened steel, so they can withstand a serious amount of rotational abuse. But apply heat (through lack of lubrication) or dirt and water (broken seal) and all hell can break loose (this is yet another reason to avoid driving through deep water). Hitting one too many potholes or taking speed bumps too quickly can also exert excessive force on your bearings, shortening their useful life.

There’s a decent chance that at some point, you’ve had your car back from an MOT test and found a patch of orange on the results that says something along the lines of ‘play in offside front wheel bearing.’ It sounds scary - after all, in order of everything you want to function correctly on your car, the wheels are pretty far up the list.

In the rail industry, lubricants play a major role in ensuring reliable operation of vehicles and infrastructure. We develop high-performance lubricants from the basis of our long-standing cooperation with manufacturers and operators contributing to the smooth functioning of your components.

Viewed over the total life cycle of a train, maintenance costs are higher than acquisition costs, so reducing maintenance costs also reduces the total cost of ownership (TCO). Lubricants are therefore much more than just an operating resource – they are an important design component.

The most common mechanical failure is due to a seal leak, which allows the lubricating grease to exit the bearing, and water and grit managing to worm its way in. This all amounts to the degradation of the balls and the outer and inner housing of the bearing, often creating that gritty, skimming sound as the wheel is rotating. Looking inside a worn-out bearing, there will often be small specs of metal that have broken off from inside the bearing itself and are grinding their way around the racers, causing more damage. If you have had a minor shunt, it’s always worth having the hub assembly checked over afterwards.

Frontwheel bearingnoise symptoms

If left to wear down further, a wheel bearing could seize and lock the axle, causing all sorts of additional damage to the drivetrain. Worst-case scenario, the wheel may come off the car altogether, so it’s best to get the car looked at as soon as possible if you suspect a dodge bearing. However, considering the forces that a drivetrain has to counteract during its lifetime of usage, it is impressive how long wheel bearings can last if inserted properly and looked after - depending on the car, original bearings can generally last for comfortably over 100,000 miles.

Most online parts stores will now sell the entire hub assembly with the wheel bearing pressed into it, saving the hassle and potential scope for mistakes within the specific bearing assembly. It goes without saying, but you should also make sure that, if possible, you or the garage is using an original manufacturer part or one of reasonably similar quality - this is one area you really don’t want to skimp on.

Catastrophicwheel bearingfailure

What happens if a wheel bearing failswhile driving

I feel dumb because I cant figure out how the bearings work with the rotating axle and how it doesnt just spin and the wheel not move.

The wheel bearing is housed within the hub assembly, providing the static connection with the hub carrier through an outer ring or ‘racer’. On driven wheels, the driveshaft travels from the transmission and passes through the centre of the wheel bearing through the inner ring, creating the rotational partnership. Ball-type bearings are generally used on the driven wheels of a vehicle, while tapered roller bearings, with cylindrical rollers arranged around an inner ring, are predominantly used on the non-driven wheels.

What is needed to render top performance spot-on? Ample experience, optimal development conditions and true team spirit. Many of our high performance lubricants are the result of many years of cooperation with companies in the railway industry. They are developed with knowledge of the specific requirements and thoroughly tested on our internal test benches, before they are made available to customers for practical tests.

What happens if a wheel bearing failswhile

They never seize immediately. No need to fear. I have a comparison to make. My Skoda had 5 out of 4 changed in its 175 000 km lifetime. Only one bearing failure might have been caused by an accident. My E46 has had the originals for 245 000 km and 13 years. And none of them seems to be on their way out.

Last year I was driving from Townsville to Brisbane. And about 800km in the wheel bearing on the rear right wheel went which shook the wheel completely off. I was only a learner at the time so it was the scariest thing that had happened to me while driving. The worst part was the car had just been serviced for the trip and the bearings had been replaced.

How to tell whichwheel bearingis bad while driving

Hey, i have driven a car to the limit where humming sound is so loud inside that you can’t even hear a Radio. They can last a long time before they go, even if they are shot.Also had an situation where from the moment bearing started to hum, till it disintegrated it self, it lasted about 2 km…. I guess it depends on how good brand you use and how lucky you are.

Klüber Lubrication offers an extensive range of specialty lubricants for the railway industry, developed with an eye to high reliability and long component lifetime. By extending relubrication intervals, our lubricants help to reduce maintenance costs and boost train availability.

A car’s wheel bearing does this by using small metal balls or cylindrical rollers that roll between two smooth rings of metal. Helped along by grease, the bearing rotates in tandem with the wheel’s rotation, the rolling motion of the balls or rollers allowing the wheel hub to rotate as freely as possible. It also helps absorb some of the forces exerted on the car’s wheel during acceleration, braking and cornering.

How unbearable, those bearings look like Lindor balls all melted up. I’m losing my bearings, I think it’s hazelnut Lindors, but i’m not sure if it’s Dark chocolate or not, or milk chocolate bearing a dark top layer. Bare with me here……….., cuz i don’t really care, I’ll eat them both.

Special lubricants for trains show that seemingly small details can have sizeable effects - on reliability, on maintenance costs and hence also on cost efficiency over the whole life cycle. What matters in this context and how you can win the race for cost efficiency becomes evident in our checklist: Lower maintenance costs combined with higher train availability!

We will keep you informed on news regarding speciality lubricants – on new products as well as on events and trade fairs where you can meet us personally.

Wheel bearings should last tens of thousands of miles, but many mechanics will simply hammer the bearing back into the hub assembly instead of precisely aligning it and using the aforementioned press. This will inevitably lead to the bearing not rotating in the perpendicular fashion that it was designed for, accelerating wear and damage to the part. It’s important, therefore, if you’re not 100 per cent confident in your own ability, to ensure you’re using a trusted, professional garage.

Trains are sold and deployed worldwide. Our specialty lubricants are therefore available worldwide under the same names and with consistently high quality. Our tribology experts are personally available for direct local advice everywhere in the world – a matter of course for Klüber customer service.

If a door gets stuck, the train stands still. Door seals on platforms and trains are highly stressed by repeated opening and closing cycles, extreme temperatures and UV radiation. The resulting frequent failures and unscheduled shop visits often cost operators a lot of money, not to mention annoyance and loss of reputation due to delays.

To replace a wheel bearing properly, it has to be popped out of the hub assembly, preferably using a hydraulic press. Problems can arise with the re-installation of the new bearing, as the alignment must be accurate to avoid the bearing wearing out rapidly and causing further pain.
