Inch Ball Screws

Precision Motion. Imperial Standard. U.S. Engineered.
Our inch ball screws feature precision-rolled or ground threads, recirculating ball technology for minimal friction, and lead accuracies that meet stringent tolerances. With diameters and lead options optimized for industrial automation, machine tools, aerospace, medical equipment, and other high-duty environments, these screws provide the performance your design depends on.


Engineered for Your Application

✦ Imperial-diameter options (inches) and optimized lead selections for North American and legacy machine tool systems

✦ Low-friction recirculating ball mechanism to improve efficiency, reduce wear, and extend maintenance intervals

✦ Custom end-machining, materials, and coatings available for environmental, load, or startup requirements

✦ Application engineering support from Helix’s U.S.–based team, assisting in selecting screw geometry, fit, preload, and installation guidance
Applications & Industry Impact

Helix’s inch ball screws are used across robotics, CNC machining, aerospace actuation, medical devices, automation equipment, and general industrial manufacturing. They are perfect for anywhere smooth, repeatable linear movement is vital. By offering imperial thread standards, Helix supports customers operating within U.S. measurement systems or migrating from older equipment without redesigning to metric.
