Abstract

The spacer is adapted for a rolling bearing comprising an inner ring an outer ring and at least one row of angular contact rollers disposed between raceways provided on the rings. The spacer comprises two opposite faces 17 18 having a concave profile adapted to the rollers each face comprising at least a contact surface 17a 18a with the associated roller having the shape of a cylinder segment. The axes of the cylinder segments of said contact surfaces converge.
