  • Bearing assembly with slotted closure cup
    Patent number: 5435655
    Abstract: A tapered roller thrust bearing assembly with an internal seal and slotted closure cup. 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. The closure cup has a side wall with a number of slots which extend from the open end of the closure cup to an intermediate point of the side wall. The slots increase the area for the escape of grease during lubrication of the bearing assembly. The slots also allow for improved consistency in crimping or bending of the side wall of the closure cup during assembly.
