SKF Ball screw bearing

Ball screw bearing is that a screw which runs on ball bearings. The screw and nut have matching helical grooves or races, and the ball bearings recirculate in these races. There is no physical contactbetween the screw and the nut. As the screw or nut rotates, andthe rolling balls reach the trailing end of the nut. They are deflected or guided from this pitch contact by means of a return tube and returned to the leading end of the circuit. There, the cycle resumes and the balls recirculate continuously.
