Play-free radial rolling bearing especially for four point ball bearings - has radial sealing ring connected to spring element and sliding on radial sealing face of inner ring.

摘要

A radial sealing ring (20) is connected directly to the spring elements (16,17) and slides with at least one sealing lip (18,19) on a radial sealing surface of the inner ring (2). The radial sealing ring is formed in one piece with the spring element. The spring element can be made from elastomer material. The radial sealing ring is pref. mounted on the spring element so that impurities cannot penetrate axially onto the inner or outer tracks nor in any possible interspaces. Where lubricant is in a housing the lubricant cannot escape through the bearing point. USE/ADVANTAGE - The radial sealing ring can be easily integrated in the inside of the bearing for cost-effective prodn. without increasing axial structural length.
