ABSTRACT:
Disclosed is a thrust bearing which includes a first member having a circular raceway disposed thereon, a second member having a circular raceway spaced apart from and aligned with the raceway of the first member, and a plurality of balls in the circular raceways and separating the two members. Each of the balls make contact at two points on the circular raceway of the first member and they also make contact at two other points on the circular raceway of the second member. The cross-sectional demensions of both the circular raceways and the balls are interrelated by an equation which insures that zero slippage occurs at the contact points between the surface of the balls and the surface of the raceways.
