Thrust bearing assembly with misassembly tab

摘要

Rolling elements are positioned between two thrust washers that are retained together as an assembly. One of the thrust washers has one or more one-way assembly tabs extending radially outwardly beyond the axially extending lip of the other thrust washer to provide an interference with a housing to prevent the thrust bearing assembly from being installed on the pilot surface of the housing "backwards". A remaining perimeter portion of the thrust washer adjacent to the one-way assembly tabs has a maximum radius less than the radius of the axially extending lip of the first thrust washer to facilitate flow of lubricant.
