OF late years, considerable developments have taken place in the application of ball bearings both to linear and to screw-motions, this being achieved by providing within the bearing a number of circuits (FIG. 1) so that the balls can re-circulate. The design of the ball-bearing screw and nut follows a similar principle to that of the bearing for linear motion, the half of a helical ball race being formed in both screw and nut, and the races in-the nut provided with a circuit for the return of the balls when they have completed their path of rolling engagement, the circuit registering exactly with the race. This principle whereby a screw threaded into a nut rotates on a continuous stream of steel balls circulating through an enclosed passage way will be clear on reference to the photograph (FIG. 2a) showing a typical assembly and the sectional view (FIG. 2b).
