Abstract
A tapered roller thrust bearing assembly with an internal seal. The seal is affixed to the inner surface of the closure cup and is totally enclosed thereby. A flexible flange portion on the seal prevents entry of debris into the bearing assembly, yet permits grease to exit the assembly. Because it is totally contained within the closure cup, the seal is protected from injury and wear. Moreover, production of the bearing assembly is simplified.
