Bearing for supporting shaft rotatable about axis, particularly for use in automotive sector, has contact portion, which is formed in concave, convex or as train of linear partial sections, where outer ring bears multiple rolling elements

摘要

The bearing (1) has an outer ring (3) formed by a convex outer surface (5), where two guide systems are spaced-apart in the direction of an axis (52). Each guide system is formed by a contact portion (9), where each partial area (11) of the convex outer surface of the outer ring cooperates with a partial section (10) of the contact portion. The contact portion is formed in a concave, convex or as a train of the linear partial sections. The outer ring bears multiple rolling elements (15) of a roller bearing unit (17).
