ABSTRACT:
A screw and nut have intermeshed helical threads which may be of a form selected from a variety of shapes; for example, a buttress thread. A ball track is formed by cooperating grooves in opposing flanks of the screw and nut threads, and a circuit of balls are disposed within the ball track. The result is a screw system with improved thrust load-carrying capability.
