Ball screw bearings are efficient, high-precision, and durable transmission components, characterized by high transmission efficiency, smooth motion, high precision, high durability, good synchronization, and high reliability.

Ball screw bearings are mainly composed of screws, nuts, steel balls, pre pressing plates, inverters, and dust collectors. Their core function is to convert rotational motion into linear motion or vice versa. This conversion process has the characteristic of a transmission efficiency of up to 90%~98%, which is 2-4 times that of traditional sliding screw systems. Therefore, it can obtain a larger thrust with a smaller torque. The design of ball screw bearings ensures low frictional resistance during motion, no vibration during start-up, and no crawling phenomenon at low speeds, thereby achieving precise control of micro feed. ‌

In addition, the temperature rise during the motion of the ball screw transmission system is relatively small. By pre tightening, axial clearance can be eliminated and the screw can be pre stretched to compensate for thermal elongation, thus achieving high positioning accuracy and repeatability. The rolling contact area of the steel ball has undergone hardening treatment, and the cyclic system process is purely rolling, with minimal relative wear and high service life and accuracy retention. Due to its smooth movement, sensitive response, no obstruction, and no slip characteristics, using the same ball screw transmission system to simultaneously transmit several identical components or devices can achieve good synchronization effects.

The characteristics and advantages of ball screw bearings make them widely used in various industrial equipment and precision instruments, including machine tools, high-speed tool machines, CNC machinery, precision tool machines, industrial machinery, electronic machinery, and fields that require high-precision, high-efficiency, and high reliability transmission.
