Abstract

A sealing system for a rotating shaft journaled in roller, ball or tapered bearings retained in a carrier includes an outer seal which sealingly engages the carrier and an inner seal which sealingly engages the shaft. In this way, the sealing velocity is substantially lowered for a shaft of a given diameter enhancing the integrity of the seal over a greater range of shaft diameters and speeds.
