Radially pre-stressed roller bearing for rack and pinion steering gear of motor vehicle servo-steering mechanism, has elastically deformable rolling body, which is smaller than that of another rolling body in its axial expansion

摘要

The bearing has cylindrical rolling bodies (6, 7) arranged in respective slots (4, 5) of a cage. The elastically deformable rolling body (7) made from plastic has a diameter larger than the body (6), and is smaller that that of the body (6) in its axial expansion, where the slot (5) is smaller than the slot (4) in its axial expansion. A discharge groove running parallel to a bearing axis is arranged in an inner ring or an outer ring.
