ABSTRACT:
A seal for a bearing having a housing with an opening therein for receiving a shaft in which a bearing assembly is mounted in the housing and has an inner race for receiving the shaft. A seal consisting of a ring having a radially extending, outwardly facing flat surface is disposed in the housing opening adjacent the inner race, and a seal which may be of the V-ring type is mounted on the inner race and has a lip which seats on and rubs against the radial surface of the ring. Collars may be used on the race to retain the lipped seal in proper relationship with the ring on the inner race. The relationship of the lip to the metal ring is such that the bearing assembly can be purged by the outward flowing of the lubricant yet protected from the ingress of foreign matter. In some modifications, an auxiliary seal, which is disposed externally with respect to the lipped seal, may be used.
