Abstract

A seal for bearings such as a bearing bushing of a universal joint having inner and outer members with confronting spaced raceways. The seal includes at least one circumferentially extending sealing lip which engages a surface of one of the members outboard of the raceway and includes stiffening or rigidifying ribs which prevents inversion of the seal upon assembling.
