Ball Screw

Ball Screw

– High-Precision Linear Motion Drive for CNC & Automation Systems

      The  Ball Screw, a critical transmission component designed to convert rotary motion into precise linear movement with minimal friction. Engineered for high-performance applications, ball screws deliver exceptional positioning accuracy, repeatability, and load capacity—making them essential for CNC machines, robotics, and advanced automation systems.

Featuring a recirculating ball mechanism, the ball screw significantly reduces friction compared to traditional lead screws, achieving efficiency levels of up to 90% or higher. This ensures smoother operation, lower heat generation, and extended service life. Manufactured with high-grade alloy or bearing steel, our ball screws provide outstanding strength, rigidity, and wear resistance even under high-speed and high-load conditions.

Available in both rolled and precision-ground types, our ball screws can be customized to meet various accuracy grades and application requirements.
