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 efficiency of rotation. This is achieved as rolling produces much less friction force than sliding.

A car’s wheel bearing does this by using small metal balls that roll between two smooth rings of metal. Along with grease, the bearing rotates in-tandem with the wheel’s rotation, the rolling motion of the balls allowing the wheel hub to rotate as freely as possible.

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