Stainless Steel Ball Screw

Stainless Steel Ball Screw

– High-Precision Corrosion-Resistant Linear Motion Drive

     The Stainless Steel Ball Screw, a precision-engineered linear motion component designed to convert rotary motion into smooth, efficient linear movement. Ideal for applications requiring high corrosion resistance, cleanliness, and long service life, this ball screw delivers exceptional positioning accuracy and repeatability.

Manufactured from premium stainless steel (e.g., SUS304 / SUS316), this ball screw is engineered for use in harsh or hygienic environments such as food processing, medical equipment, and marine systems. The recirculating ball mechanism minimizes friction, enabling high efficiency (up to 90%+) and reduced wear compared to traditional lead screws.

With precision-ground or rolled threads and optimized preload options, our stainless steel ball screws ensure stable performance, low backlash, and consistent motion control across a wide range of industrial and automation applications.
