FIRST GENERATION – Compact wheel bearings
Closed wheel bearings with double row ball bearings and ‘split inner ring’ that ensures that each ball bearing can rotate independently. With this generation, the hub must be purchased and installed separately.
SECOND GENERATION – Wheel bearings with integrated wheel flange
These wheel bearings are also equipped with ball bearings, but contain an integrated wheel flange mounted directly on the wheel and the brake disc. A separate hub is therefore no longer required. Where necessary, these wheel bearings are equipped with an ABS sensor ring.
THIRD GENERATION – Wheel bearings with two integrated flanges
Wheel bearings of the third generation are equipped with two flanges: one for direct mounting on the wheel and the brake disc and one for direct mounting on the suspension. Where applicable, these wheel bearings are equipped with an integrated ABS sensor.
