ABSTRACT:
The thrust race comprises circumferentially spaced tabs on the outer flange with cutouts located circumferentially adjacent each side of each tab.
The thrust race is formed from sheet metal. Annular blanks are blanked in the sheet metal, the cutouts are made on the outside perimeter of the annular blank, the tab between each pair of cutouts is formed, and the annular blank then removed from the flat sheet metal. The outer portion of the annular blank is bent to form an axially extending outer flange having a plurality of circumferentially spaced tabs extending inwardly from the flange toward the bore of the thrust washer with cutouts located circumferentially adjacent each side of each of the tabs.
