Ball screws assemblies offer an efficient means of converting rotary motion to linear motion. A ball screw is an improvement over an acme screw just as an antifriction ball bearing is an improvement over a plain bushing. Precision ball screws have a number of bearing balls that transfer the load between the nut and screw.
A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction.A 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.
