NSK ball screws have been continuously developed through cutting-edge tribology, and we have become the largest volume manufacturer in the world with its outstanding production and quality control techniques. We have been busy producing ball screws since 1958; more than 1,000,000. Among the types of precision ball screws made are standard, custom, metric ball screws and miniature ball screws.
Ball screws are mechanical linear actuators that consist of a screw shaft and a nut that contain a ball that rolls between their matching helical grooves. The primary function of ball screws is to convert rotational motion to linear motion. Ball nuts are used in...
A lead screw is a kind of mechanical linear actuator that converts rotational motion into linear motion. Its operation relies on the sliding of the screw shaft and the nut threads with no ball bearings between them. The screw shaft and the nut are directly moving against each other on...
A linear actuator is a means for converting rotational motion into push or pull linear motion, which can be used for lifting, dropping, sliding, or tilting of machines or materials. They provide safe and clean...
