Wheel bearings are a crucial component because they let the wheels rotate while supporting the weight of the entire vehicle. When they become faulty, your vehicle’s wheel hubs are going to create noises and vibrations while you’re driving, which can be unnerving. They can fail catastrophically and cause your wheel to seize, which can result in a crash. Replace your faulty wheel bearings immediately with new ones from CarParts.com.

Despite the similar term, bearing units are not to be confused with bearing housings, about which information can also be found on bearingwizard.co.uk.

Wheel bearings are generally designed to last the lifespan of your vehicle. However, driving conditions, habits, and other factors can cause them to fail like any other car part.

Bearing units can be mounted on drawn shafts because the bore is always 0+ tolerance (larger than the nominal diameter of the shaft). Special machining of the shaft surface is therefore not necessary.

The cost would be the same as a replacement, as there’s no other way to fix a damaged wheel bearing than to replace it with a new one.

Shaft mounting with an adapter sleeve is somewhat more complex and must be carried out professionally. Due to the number of additional components, bearing inserts with adapter sleeves are also somewhat more cost-intensive. However, with this mounting method you benefit from a very high clamp force, low-vibration running and higher speeds.

The simplest and most economical mounting method is bearing inserts with set screws. The inner ring is equipped with two set screws offset by 120°. By tightening the two hexagon socket screws, the bearing inner ring is fixed to the shaft and locates the bearing unit. The recommended tightening torque must be observed when tightening the set screws. A normal Allen key is sufficient as a tool. With this method, the axis of the bearing insert is offset slightly from the centre of the shaft axis. This slight offset can lead to vibrations at higher shaft speeds, but is not relevant for applications with normal speeds. In contrast to bearing inserts with an eccentric collar, the bearings with set screws are also suitable for alternating directions of shaft rotation.

The selection of the right material also plays an important role in the reliable operation of a bearing unit. NTN’s portfolio includes bearing units with housings made of steel, spheroidal graphite cast (ductile) iron, grey cast iron, pressed steel, stainless steel and thermoplastic. Due to the very high variance of different designs and materials, bearing solutions can be achieved for many industrial applications.

Rollers on this type of bearing are secured in a cage between the inner and outer races. The tapered roller bearing is expected to move around the cage freely to allow heat expansion.

These anti-friction wheel bearings come in the form of ball, roller, and tapered roller bearings. And while each of them has distinctive features, they all perform the similar task of converting sliding friction into a rolling motion.

Just like spherical roller bearings, bearing inserts can also have a tapered bore. However, these are usually mounted on a cylindrical shaft by means of an adapter sleeve. Adapter sleeve mountings generally represent a very secure shaft connection. During mounting, the bearing is pushed onto the sleeve until the recommended reduction in radial internal clearance is achieved. Setting the correct internal clearance value is crucial for the service life of the bearing. The bearing is secured in this position with a lockwasher and locknut.

The mounting method using an eccentric collar is also very common in industrial machines. With this fastening method, the bearing insert is mounted together with an eccentric collar. The eccentrically machined collar on the inner ring and the eccentric recess on the eccentric collar are clamped together during mounting and ensure the fixation of the bearing on the shaft. The eccentric collar must be fixed in the direction of rotation of the shaft and finally secured with a set screw. This type of mounting is not suitable for quick changes in the direction of rotation, as the eccentric collar could come loose during alternating operation. The larger installation space required by the additional component must also be taken into account.

Double-row Angular Contact Ball Bearings · The construction of this ball bearing is similar to mounting two single row angular ball bearings back to back(DB).

If you have read our article on rolling bearing basics, you probably already know that rolling bearings can basically be divided into two types –

Ball bearings reduce friction by using hardened steel balls between the inner and outer races. This type of wheel bearing is designed to operate at high speeds and control an axle shaft’s thrust movement.

Although there is less friction when using ball bearings, they’re not made to support the same weight as roller bearings.

Some vehicles also have needle bearings, which is a type of roller bearing that uses smaller needle rollers. This type is not adjustable because the clearance between the diameter of the straight roller is manufactured into the bearing itself.

In contrast to deep groove ball bearings, bearing inserts generally have a seal. They are pre-greased and in most cases can be re-greased via a lubricant feed in the housing. An integrated clamping system on the inner ring allows easy mounting on cylindrical shafts.

While the locating bearing side can absorb forces in radial and axial directions, the shaft on the non-locating bearing side remains displaceable – but absorbs forces only from the radial load direction. Bearing inserts from SNR (an NTN brand) with set screws, for example, can be easily converted for use as non-locating bearings.

For mounting a standard deep groove ball bearing on a shaft, the inner ring is usually heated by means of an induction heating device for warm mounting. Special mounting tools are used for cold mounting. In both cases, mounting is significantly more complex and costly than for bearing inserts with an integrated mounting system.

Wheel bearings let the wheels rotate while supporting the entire vehicle. These bearings come with rolling parts inside them that help reduce friction.

The bearing insert, which in principle is constructed like a deep groove ball bearing, has a spherical outer ring surface. The seat in the housing, on the other hand, is a spherical recess and enables the bearing insert to be held securely without the need for further fastening elements. This configuration allows the bearing to absorb loads in the radial and axial directions and to compensate for slight shaft misalignments.

What is meant by “point and line contact”? You may have already heard that rolling bearings can be split into two types. The classification depends

The assembly and disassembly of the units can be carried out without special prior knowledge and special assembly tools.

Roller bearings have rollers between the inner and outer races to reduce friction. Compared to a ball bearing, this type has a longer contact area to support heavier loads.

Because both the bearing and rollers are tapered for this type, it can accommodate more weight. Unlike other types, the load on the tapered roller bearing is directed over the entire length of each roller instead of concentrating on a small spot.

There are various methods available for mounting a bearing insert on cylindrical shafts. The most suitable fastening system is determined by the application. From a design point of view, the maximum permissible speed, the direction of rotation of the shaft and the running behaviour as well as the effect of axial loads must be taken into account. Furthermore, economic aspects, the available installation space and the ease of installation can be decisive for the choice of fastening system.

Characteristics of deep groove ball bearings In its current form, the deep groove ball bearing has existed – subject to some optimisation – for about

The simple assembly of the units does not require any special prior knowledge on the part of the fitter. However, the operating conditions and mounting instructions must be observed. When planning, the loads, speeds and operating temperatures for the respective application must be considered, almost like any other bearing calculation. Furthermore, the consideration of sealing and the type of lubricant should play a role in the design of the bearing configuration. In practice, rolling bearings with ball type rolling elements are almost exclusively used for bearing units. The bearing geometry is identical to that of deep groove ball bearings of series 62 and 63. The limiting speed of bearing inserts is lower than that of comparable deep groove ball bearings due to the special mounting method on the shaft.

In some cases, you might even need to replace the entire hub because you won’t be able to get to the damaged bearing without disassembling the entire unit.

Once this happens, you’ll notice that the brake pedal feels low or spongy because the piston is traveling farther than normal to apply braking power.

A damaged or worn-out wheel bearing can cause the brake rotor to wobble on its axis, which can push the caliper piston into its bore.

Bearing arrangements that can compensate for heat-related changes in the length of shafts are referred to as non-locating (floating) bearings. In order to avoid bearing failures due to axial tension, the shaft must be supported via a locating and non-locating bearing.

Driving with a bad wheel bearing is never a good idea. Aside from compromising your safety, you also risk damaging other parts of your vehicle, which can lead to costly repairs down the road. In extreme cases, driving with a bad wheel bearing can even cause one of your wheels to fall off while driving.
