ABSTRACT:
The cartridge comprises an anti-friction bearing positioned between rotating seals. At one end of the bearing the outer race makes rotary sealing contact with rim of an annular sealing disk of softer material than the bearing race. At the other end of the bearing the outer race is urged axially against the sealing disk by a resilient member. The other end of that member presses against a second annular sealing disk having a flange around its central opening which forms a rotary seal with a shaft extended through the cartridge. The bearing cartridge during assembly is partially filled with lubricant and rotation of the bearing causes lubricant to be thrown against the inner surface of the bearing and the cartridge by centrifugal force and circulated thereby through the load-carrying area of the bearing in the direction of the pressure applied by the resilient member and back through the remainder of the bearing.
