ABSTRACT:
A linear motion ball bearing assembly and shaft having ball conforming portions are combined to support heavier-than-normal loads and provide torque resistance. The bearing shaft is provided with one or more ball conforming grooves. The bearing assembly is provided with one or more load-bearing surfaces, each of which also includes a ball conforming groove, which may move circumferentially a very slight amount for tolerance variations in the angular spacing and parallelism of the shaft grooves, thereby assuring perfect ball conformity and line contact on the load-bearing surface of both the shaft and bearing assembly. Alternative configurations and methods of forming the ball conforming grooves on the shaft are also disclosed.
