    Lifetime of a Ball Screw. Ball screws have very low friction coefficients, which is the key to both their accuracy and their longevity. The actual life is determined by load, speed, lead and screw size. Common values are 20,000 hours, and 50,000 km or 5 years. Required Maintenance for a Ball Screw

  • Ball Screw Terminology Dynatect Manufacturing Inc.

    Ball Screw vs Acme Lead Screw: A ball screw is a mechanical device that translates rotational motion to linear motion. Ball screws are typically 90% efficient at converting input torque to thrust. Compared to lead screws, ball screws are generally more bulky, because of the need to have a mechanism to re-circulate the balls.
