Seal for use between rings of roller bearing for e.g. retention of grease, has flange including edge axially projecting relative to radial region and defining annular space together with ring, where space is filled with lubricant

摘要

The seal (22) has a flange (30) and a sealing region forming dynamic sealing with a ring (16) and static sealing with another ring (14). A static sealing region includes a sealing part (32) partially surrounding an end of a radial region (34) of the flange. The flange includes an edge (38), which extends from another end of the radial region radially opposite to the former end and forms a dynamic sealing region. The edge axially projects relative to the radial region and defines an annular space (40) together with the former ring. The space is filled with lubricant i.e. grease.
