Wheel Bearing Housing

4050 Wheel Bearing Housing

To reduce weight, the wheel bearing housing is no longer manufactured as a solid unit, but as a torsionally and rigid hollow-cast unit. The design of the wheel bearing housing was modified in order to optimize the supply of cool air to the brakes. This measure, together with an enlarged brake air deflector which is attached to the cross member, has resulted in improved brake cooling.

The installation position of the ABS sensor has been adapted to fit the altered pulse reception (see wheel bearing). Depending on the brakes version (grey cast iron/PCCB), the wheel bearing housings are machined differently in the vicinity of the brake caliper mounting.
