STRA Series Wide-Opening Self-Centering Steady Rest

The Samchully STRA Series Wide-Opening Self-Centering Steady Rests are engineered for lathes and turning centers requiring secure support for long bars and pipe, especially in applications that benefit from vertical loading. Designed for both fixed and travelling configurations, the STRA Series is ideal for automated machining cells and high-production environments where accessibility, repeatability, and stable workpiece support are critical.

The STRA series features a wide-opening arm design that allows for easy vertical loading and seamless integration with automation systems. Its self-centering mechanism interconnects the arms and center rollers, enabling automatic adjustment to varying workpiece diameters without manual intervention. The spring-free mechanical design improves durability and long-term reliability while maintaining precise centering and repeatability. Engineered for demanding machining conditions, the STRA series supports roller surface speeds from 800m/min to 700m/min and delivers strong, evenly distributed clamping force across a wide centering range. Available in both fixed and travelling configurations, the STRA series provides a robust, automation-ready steady rest solution for modern turning applications.
