Ball Screw Maintenance (Lubrication and Cleanliness) A ball screw must be properly lubricated and kept clean at all times. Otherwise its life will be reduced. When ball screws are not lubricated, the wear life drops by as much as 85percent. Lubrication reduces friction, prevents corrosion and allows the ball screw to operate more efficiently.

How A Ball Screw Works A. The Ball Screw Assembly. The ball screw assembly consists of a screw and a nut, each with matching helical grooves, and balls which roll between these grooves providing the only contact between the nut and the screw. As the screw or nut rotates, the balls are deflected by the deflector into the ball return system of the nut and they travel through the return system to
A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction.

Ballscrew actuator operation and iterations. Ball screws use a thread form that has a circular shape. The nut has a matched thread form, allowing ball bearings that fit between the grooves to transmit force and relative motion with high efficiency. Ballscrew actuators typically have efficiencies around 80%.
