The radial bearing (1) consists of outer (3) and inner (4) metal rings with races (5) for rolling bodies (2) such as balls or rollers in a metal cage (6) with a hardness similar to that of the rings. The radial bearing (1) consists of outer (3) and inner (4) metal rings with races (5) for rolling bodies (2) such as balls or rollers in a metal cage (6) with a hardness similar to that of the rings. It also has at least one circular contact ring (7a, 7b, 7c, 7d) made from a material with a different hardness to the bearing rings and cage, set in one or more grooves (8) in the bearing rings and preventing any direct contact vbetween the cage and bearing ring(s) with the groove(s). The contact rings can be made from a non-ferrous metal such as a copper alloy or bronze, or from a polymer material. |
