Abstract
A cage-less thrust bearing includes first and second washers concentrically arranged such that the washers cooperate to define a ball chamber having a first pair of opposing axially extending race surfaces and a second pair of opposing radially extending race surfaces. A plurality of balls are disposed in the ball chamber without being retained by a cage. Each ball is configured to ride on each of the race surfaces.
