Ball screw is an ideal product to convert rotary motion into linear motion, or convert linear motion into rotary motion.

BallScrews, also called a ball bearing screws, recirculating ballscrews, etc., consist of a screw spindle and a nut integrated with balls and the balls' return mechanism, return tubes or return caps, ballscrews are the most common type of screws used in industrial machinery and precision machines, the primary function of a ballscrews is to convert rotary motion to linear motion or torque to thrust, and vice versa, with the features of high accuracy, reversibility and efficiency, EASIER Provides a wide range of ballscrews to satisfy your special requirements.

Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force. It also has high precision, reversibility and high Features of efficiency. Because of its low frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.



The ball screw is composed of a screw, a nut, a steel ball, a pre-compression piece, a reverser, and a dustproof device. Its function is to convert rotary motion into linear motion, which is a further extension and development of Akem screw. The important significance of this development is to change the bearing from sliding motion to rolling motion.


In order to adapt to various purposes, ball screw bearings provide a wide range of standardized products. Widely used in machine tools, the ball circulation methods include circulating duct type, circulator type and end cap type. Preloading methods include positioning preloading (double nut method, position preloading method) and constant pressure preloading. The appropriate type can be selected according to the purpose. The screw has high-precision grinding precision ball screw (precision is divided into 6 grades from CO-C7) and cold-rolled ball screw bearing formed by high-precision cold rolling (precision is divided into 3 from C7-C10) Levels). In addition, in order to cope with the urgent delivery of users, there are finished products that have been processed on the shaft ends, semi-finished products and cold rolled ball screw bearings that can be freely processed on the shaft ends. As the peripheral parts of this bearing, the screw support unit, nut support, lock nut, etc. necessary for use have also been standardized and can be used by users.


Ball screw bearings are based on product technology accumulated over the years, from materials, heat treatment, manufacturing, inspection to shipment, are managed by a rigorous quality assurance system, so they have high reliability
