Spherical roller bearings are known for their robustness and ability to support high radial loads and moderate axial loads.

This arrangement also provides very high radial load ratings and increased rigidity. However, they are limited in the axial loads they can carry.

If you’re aware that there’s an issue with your car’s wheel bearing, it’s best to take it straight to a mechanic for a full diagnosis and repair. Often, it may just be a case of relubricating the ball bearings within the assembly before repacking them, which is significantly simpler to put right than the alternative.

The cost of a wheel bearing replacement in the UK is roughly £150-£300, dependent on the make and model of your car and a mechanic’s labour costs. The good news is that you don’t need to replace all wheel bearings at once if the other three remain in a safe and serviceable condition.

Continuing to drive on a bad wheel bearing can lead to extensive and critical damage which will be significantly more expensive to repair than a simple bearing re-grease and service. And in the worst cases, the damage from a faulty bearing that goes untreated can prove impossible to fix, particularly if it contributes to corrosion of surrounding components and the axle.

Bearing materials must be compatible with the surrounding materials to prevent corrosion and undesirable chemical reactions.

Some bearing types are more difficult to mount or dismount than others. This must be considered, especially in applications where frequent stoppages are not possible.

Types of bearings

These bearings are best suited for applications requiring small, precise oscillations with limited torsion, such as gimbals, vibratory hoppers and optical devices.

The outer ring is fixed to the bearing housing and does not rotate. It supports the rolling elements on the opposite side.

They work on the same principle as self-aligning ball bearings, except that they use spherical rollers instead of balls, allowing them to carry higher loads. They can also compensate for misalignment between the shaft and housing.

Replacing all of your car’s wheel bearings might cost an eye-watering sum, but it’s guaranteed to be a lot cheaper than repairing the damage should a bearing fail.

In general, ball bearings can achieve very high rotational speeds, but they cannot support very heavy loads because the small contact area results in low friction and therefore low load resistance.

Radial bearings carry loads perpendicular to the axis of rotation (along the radius), while axial bearings carry loads parallel to the axis.

Roller bearings have linear contact, in which the rollers contact the raceways in a line. This type of contact allows roller bearings to carry heavier loads than ball bearings of similar dimensions.

The inner ring is the part of the bearing that is usually mounted on the rotating shaft. It rotates with the shaft and carries the rolling elements.

Ball bearing

Spherical roller bearings are essential in many industrial applications where heavy loads and harsh conditions are commonplace. They can be found in stone crushers and mills, rolling mills, and pulp and paper machines.

But such widespread use means that there are many different types of bearings, each with characteristics that make them suitable for their particular purpose.

Needle roller bearings provide excellent rigidity and very high load carrying capacity for their size, but can only support radial loads.

Needle roller bearings are a type of cylindrical roller bearing whose rolling elements are characterized by their long, thin, needle-like shape (needle roller bearings are usually defined by a diameter/length ratio between 1:3 and 1:10).

This type of bearing can withstand a certain amount of misalignment and multidirectional motion, and is suitable for both static and dynamic loads. They are widely used in agricultural, automotive, construction and industrial applications.

These bearings can support high radial loads as well as large axial loads in one direction. In a double configuration, they can support axial loads in both directions.

Cylindrical Roller Bearings use linear contact between rolling elements and raceways, which optimizes the stress distribution at the contact point and reduces friction.

However, due to the larger contact area, which generates more friction, their maximum rotational speed is lower than that of ball bearings.

Linear ball bearings, also known as linear ball bushings, take the form of a cylindrical sleeve containing balls arranged in rows. These balls roll in precise raceways to provide smooth, accurate linear motion along the shaft or rail axis.

Bearings are also useful for transmitting motion by supporting and guiding components that rotate relative to each other. In effect, they limit the freedom of movement of moving parts to predefined directions.

These bearings are commonly used in opposed pairs (X or O arrangement) to carry axial loads in both directions. This allows them to be used in applications where combined loads and severe operating conditions are common.

Once you’ve performed this basic wheel bearing test, you should have a better idea of where the problem is. Then, it’s a case of diagnosing the front or rear wheel on the side in question.

The outer ring raceway of this type of bearing is spherical, which allows the inner and outer rings to self-align and compensate for angular misalignment. For this reason, they are known as “self-aligning” bearings.

Because of their abundance, it would be almost impossible to list all the devices whose operation depends on the use of bearings. In both industry and everyday life, bearings are literally everywhere: production machinery, motorized equipment, power tools, household appliances – the list goes on and on.

Frictionless bearings work by using rolling elements (such as balls or rollers) to reduce friction between moving surfaces.

These rolling elements can be balls, cylindrical rollers, tapered rollers or needles, depending on the bearing type and application requirements.

As you’ll know from our car maintenance glossary, bearings allow the wheels to turn freely without generating huge amounts of heat. If a bearing were to fail, the wheel can seize up altogether, resulting in catastrophic damage and the potential for a serious incident. Indeed, in the very worst-case scenario, a failed bearing can cause the wheel to rip away from the car entirely.

To do that, you’ll first need to jack up your car so that both wheels are off the ground. We would strongly recommend using service ramps for this to ensure you can carry out the following checks safely.

Deep groove ball bearings derive their name from the fact that their inner and outer ring raceways have deep grooves that allow better load distribution. In fact, they can support not only high radial loads but also moderate axial loads in both directions.

In some applications, both radial and axial loads are required. In such cases, combined bearings can be used to support radial and axial loads simultaneously.

They are widely used in applications with high radial loads that require high precision: industrial gears, conveyors, machine tools, paper machine cylinders.

This ultrasonic leak detector includes a transmitter, headphones, a carrying case, and batteries. It has a frequency response of 40 hertz to 40 kilohertz.

The rolling elements are located between the inner and outer rings. They allow relative rotation between the rings to reduce friction.

Since budgets are rarely unlimited, it’s a good idea to consider the initial cost and long-term costs (maintenance, lubrication, replacement) associated with each bearing type before selecting one for an application.

When the car is elevated and in place, take hold of each wheel in turn and wiggle it backwards and forwards, side to side. If there is any play in the wheel, it feels wobbly or loose, or an unusual noise accompanies some minor movement, then you’ve found the problem wheel.

Thrust ball bearings are designed to carry axial loads only. They consist of two bearing rings, called washers, with raceways. One of the washers is mounted on the shaft while the other is fixed in the housing.

A bearing is a mechanical device whose primary purpose is to prevent direct metal-to-metal contact between two elements in relative motion.  This prevents friction, heat generation and ultimately wear.

In conclusion, there are a wide variety of bearing types, each with unique characteristics that make them effective or ineffective in a given industrial application.

In fact, the plain bearing is essentially a sleeve mounted on the shaft that fits into the bore. Plain bearings are inexpensive, compact, and lightweight while offering high load carrying capacity.

These radial bearings. Often referred to as skate bearings. They're good for supporting a rotating rod or as a wheel hub.

Deep groove ball bearings can achieve very high speeds, making them ideal for applications that require fast, continuous motion. What’s more, they can tolerate slight misalignment of the inner and outer rings without significantly affecting bearing performance.

Plain bearings are used for rotating, sliding, reciprocating or oscillating motion. They remain stationary as the shaft slides over their inner surface. Material pairs with low coefficients of friction (e.g. copper alloys) are selected to facilitate smooth motion.

It should be noted, however, that this list is not exhaustive and that for each type there may be variants that multiply the field of possibilities:

If you suspect you have a wheel bearing fault but aren’t sure which side of the vehicle is affected, there’s a safe and simple test you can use to check. Our step-by-step guide below can take you through how it’s done…

In this article, our industrial mechanics specialists provide a brief overview of the most common types of bearings. Along the way, you’ll also learn about bearing components and how to select a bearing for a specific application.

To avoid breakage and the need for constant bearing replacement, it is essential to consider the expected life of bearings under the load and operating conditions specific to the intended application.

These bearings are particularly suitable for applications where angular misalignment is unavoidable. Their self-aligning capability, combined with good radial and axial load carrying capacity, makes them indispensable in a wide range of industries.

These bearings are also known for their increased rigidity under load, which is beneficial in applications requiring high precision.

Given the damage that can occur as a result of a failed wheel bearing, not to mention the dangers, this further reinforces the importance of getting those bearings checked and repaired the moment you realise there’s a problem.

Lubricated bearings, sometimes called plain bearings, work by using a lubricating film (such as oil or grease) to reduce friction between sliding surfaces in relative motion.

Although primarily designed for linear motion, they can also support moderate radial loads, providing good rigidity and stability.

You can still drive with a bad wheel bearing, but we wouldn’t recommend it for long distances. Keep your mileage to a minimum and look out for worsening symptoms of a wheel bearing fault; we cover the symptoms to check for later in this guide.

Crossed roller bearings are characterized by cylindrical rollers arranged alternately in a vertical direction, which enables them to carry multidirectional loads (axial and radial) with high rigidity and precision.

Typically, wheel bearings have a lifespan of around 85,000 to 100,000 miles, so if your car is approaching these kinds of figures, it’s important to keep an eye on the tell-tale signs of a bearing in decline.
