Abstract: A rolling bearing arrangement for an anti-locking brake system has a pulse ring with projections directed toward the fixed ring. The surfaces of the projections that activate the pulse generator are cut during the hard working of the bearing ring. The pulse generator is integrated in the rolling bearing arrangement. Thereby, on one hand, tolerance limited operational differences in the amplitude and shape of the pulses are avoided, especially during slow rotational speeds of the bearing ring. Furthermore, external influences on the pulse generator and pulse ring caused by rough roads do not occur due to the hermetic encapsulation of the sensitive components.

Abstract: An electrical connection, preferably for ALS sensors incorporated in wheel bearings, is installed coaxially on the wheel bearing and its side surface. It is equipped, for example, with slip rings which operate in conjunction with the electrical contacts of the ALS sensor which is solidly attached to the wheel bearing. This simplifies the manufacture and handling of the wheel bearing during transportation and assembly. In particular, the risk of damage to the connecting cord is reduced during operation.

Abstract: A spherical roller thrust bearing comprises two bearing rings rotatably guided by spherical roller elements for rotation about an axis. The roller elements are spaced circumferentially apart by a segmented retainer comprising separate retainer segments spaced apart in the circumferential direction. Each retainer segment includes opposite circumferentially facing surfaces engaging adjacent roller elements. Each surface includes at least one projection making point contact with a peripheral surface of a roller at a location whereby the force transmitted between the roller elements by the segments excludes a radially inward force component. The projections are located relative to the roller elements such that the segments tend to hang upon the roller elements.

This lateral surface section is adjacent to the outside end surface of the flange section of the outer ring. The inner surface of a centering extension is tightly seated on the ring-shaped extension.
