Claims
- 1. A thrust and radial ball bearing for use with rotatable shaft comprising: a pressed metal cup having end flanges; a single loosely-mounted annular thrust washer retained in the metal cup by one of said end flanges and adapted to fit loosely about the rotatable shaft so as to be axially movable with respect to the pressed metal cup; and a plurality of balls adapted to be contacted by the annular thrust washer, the diameter of each ball and the thickness of the thrust washer being such that an axial clearance exists between said one end flange and the thrust washer when a force exerted by the rotatable shaft in the proper axial direction is transmitted to the thrust washer to cause said thrust washer to engage the balls, and the balls to engage the other end flange of the cup.
- 2. A thrust and radial ball bearing comprising: a pressed metal cup having end flanges; a central thrust washer and two end thrust washers loosely retained in the metal cup by the cup flanges, and two sets of balls, each set of balls adapted to contact the central thrust washer and an end thrust washer, and an axial clearance exists between one cup end flange and one end thrust washer when a force is exerted against said one end thrust washer in the proper axial direction and said thrust washer engages one set of balls, said set of balls engages the central thrust washer, the central thrust washer engages the other set of balls, the other set of balls engages the other end thrust washer, and the other cup end flange is engaged by said other end thrust washer.
