Abstract
Two thrust races are separated by a plurality of rolling elements for relative rotation of the thrust races about a common axis. A spring washer is positioned axially outward of the two thrust races for engaging a support surface and for applying an axial load to one of the two thrust races. The two thrust races, the rolling elements and the spring washer are retained together as an assembly, for example by an axially extending case with radially extending lips, to facilitate handling and installation of the thrust bearing assembly.
