history of development
The history of people using screws for transmission is actually not very long. Traditional screws have always had poor positioning and are prone to damage. Until 1898 AD, people first attempted to place steel balls between nuts and screws using rolling friction instead of sliding friction to improve their poor positioning and susceptibility to damage. In 1940, ball screws were further incorporated into automotive steering systems, marking a significant revolution in the application of ball screws and gradually replacing traditional ACME screws. Until recent years, ball screws have become one of the most widely used components in the industry.
principle
Ball screws are used to convert rotational motion into linear motion; Or an actuator that converts linear motion into rotational motion, with high transmission efficiency and accurate positioning. When the ball screw serves as the active body, the nut will be converted into linear motion according to the corresponding specifications of the lead as the screw rotates. The passive workpiece can be connected to the nut seat and nut to achieve corresponding linear motion.
Ball screw is the most commonly used transmission component in tool machinery and precision machinery. Its main function is to convert rotational motion into linear motion or torque into axial repetitive force, while also possessing the characteristics of high precision, reversibility, and high efficiency. Due to its low frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.
A ball screw consists of a screw, nut, steel ball, pre press plate, reverser, and dust collector. Its function is to convert rotational motion into linear motion, and the significance of this development is to transform bearings from sliding motion to rolling motion.
Purpose
Ball screw bearings provide a wide range of standardized products to adapt to various applications. Widely used in machine tools, the circulation methods of ball bearings include circulation guide tube type, circulation device type, and end cap type. The preloading methods include positioning preloading (double nut method, position preloading method) and constant pressure preloading.

Suitable types can be selected based on their intended use. The screw has precision ball screws with high-precision grinding processing (accuracy divided into 6 levels from CO-C7) and cold-rolled ball screw bearings formed by high-precision cold rolling processing (accuracy divided into 3 levels from C7-C10). In addition, to meet the urgent delivery needs of users, there are also finished products that have been processed on the shaft end, semi-finished products that can be freely machined on the shaft end, and cold-rolled ball screw bearings. As peripheral components of this bearing, the necessary screw support units, nut supports, locking nuts, etc. have also been standardized and are available for users to choose from.
Ball screw bearings are based on years of accumulated product technology, and are managed by a rigorous quality assurance system from materials, heat treatment, manufacturing, inspection to shipment, thus having high reliability.
