Abstract
The invention concerns a radial rolling bearing having cylindrical rolling elements which roll between an inner and an outer ring while individual spacers are disposed between every two adjacent rolling elements, the spacers comprising, on both sides of their central longitudinal plane, contact surfaces while being guided during rotation of the radial rolling bearing by one of their end sections on a raceway of the inner or the outer ring.

A radial rolling bearing having cylindrical rolling elements (2) which roll between an inner and an outer ring (11, 10) while individual spacers (1) are disposed between every two adjacent rolling elements (2), the spacers (1) comprising, an both sides of their central longitudinal plane (3), contact surfaces (4) while being guided during rotation of the radial railing bearing by one of their end sections (4a) on a raceway of the inner or the outer ring (11, 10), characterized in that one portion (5) of the contact surfaces (4) on each side of a pitch circle (12) of the radial rolling bearing has a convex, a concave or a flat contour, and that the contact surfaces of at least one end section of each spacer are concave having a radius of curvature (7) which is larger than the radius of curvature (8) of the rolling elements (2), and in case of a concave configuration of said portion (5), a radius of curvature thereof is larger than the radius of curvature (7) of the contact surfaces of the end sections (4a).
