This is a ball screw that uses a screw shaft and ball screw nut that have been processed with high precision!

THK precision ball screws are standardized in a wide variety of types, allowing for the selection of the optimal product according to the application, with high-precision grinding processing performed on the screw shaft and ball screw nut. The nut and screw shaft of the ball screw can convert rotational motion into linear motion, or linear motion into rotational motion, through rolling motion via balls. The balls can perform infinite motion by being returned from the end face of the ball screw nut by circulating components.
