BEARING AND BEARING SEAL

摘要

A bearing is disclosed comprising two relatively movable parts with one of them having an arcuate outer surface. A seal of special construction is used to entrap lubricant and keep out water and dirt. The seal has three sealing edges. Each of the three sealing edges contacts the movable member having the arcuate outer surface, providing two voids to entrap lubricant which acts to lubricate the sealing edges and provides additional sealing.
