Wheel Hub: Description and Operation

Wheel Bearing Housing

The wheel bearing housing, which is designed as a torsionally and flexurally rigid hollow cast unit, has been adapted to the new 911 Turbo in various areas. As the wheel bearing is provided with the multi-pole seal for active ABS sensors, the installation position of the ABS sensor has been adapted to the modified pulse tapping process. Depending on the brake version (grey cast iron or PCCB), the wheel bearing housings are machined differently in the vicinity of the brake caliper mounting.
