The Schaeffler Group's range of FAG wheel bearings is more compact, lighter and offers simplified mounting via a self-centring, axial spur-gear teeth design.

A reduction in weight of 10 per cent typically amounts to an overall weight reduction of around 1kg for a four-wheel vehicle.

The FAG wheel bearing has a spur-gear teeth design, in which the wheel bearing and axle journal are connected axially rather than radially.



This has resulted in a bearing module that is lighter and can be mounted clearance free.

Driving characteristics are therefore improved and automotive manufacturers benefit from a simple mounting process and the associated cost reductions.

The new FAG wheel bearing with spur-gear teeth is better equipped to deal with the loads that occur during vehicle operation.

The spur-gear teeth ensure positive connection between the wheel bearing carrier and the input shaft, which simplifies mounting.

The self-centring axial-gear teeth are placed on the axle journal and fixed in place using a central screw.

Unlike radial-gear teeth, this mounting procedure does not require significant force.

The bearing remains clearance free but securely held in place during vehicle operation.

Having four lighter wheel bearings on the vehicle reduces the unsprung masses, which improves the driving characteristics and contributes to a reduction in CO2 emissions.

The economical production of the FAG wheel bearing was made possible by the use of an orbitally formed shoulder as the carrier of the gear teeth.

The spur-gear teeth are applied onto the orbitally formed shoulder by high-precision cold forming.
