Abstract

The sealed bearing has several rollers (3) which run on the shaft (5). The rollers are held in a cage ring (4) which surrounds each roller. The outer race (6) is separated from the roller by a sleeve (1) which fits over the end of the shaft and extends over the edge of he cage and is folded over the underneath side. The underside of the sleeve is in contact with a sealing ring (15) which rests in the groove (17).
