TEN-HIGH Bi-Directional Ball Screw SFU1204, Right and Left Hand Dual Direction Precision Lead Screw with 2 Ball Nuts for CNC Automation and Clamping Systems(Length 500mm/19.7",No End Machining)

The bi-directional (right & left hand) ball screw is designed for high-precision linear motion where two nuts move simultaneously in opposite directions. Featuring right-hand and left-hand threads on a single shaft, this advanced design allows compact, synchronized, and efficient motion — perfect for CNC automation, dual-axis actuators, and symmetrical clamping mechanisms. Each screw is crafted from premium alloy or stainless steel, with precision-ground threads to guarantee smooth movement, high transmission efficiency, and minimal backlash. Whether you’re building a central clamping system, dual push-pull stage, or a precision positioning platform, this screw ensures accuracy, stability, and long-lasting performance.
