    Many of our top units are backed by the strength of our Cyclo Technology--a long-lasting gear drive solution for any application.

    As leaders in the Power Transmission industry, your operation deserves a gear unit that won't quit. Due to the cycloidal disc design, the reduction components run as a smooth, rolling motion to prevent tooth breakage typical in conventional gearing. The result is a durable solution with a renown, long-lasting gear drive that includes:


    • Minimal vibration

    • 500% Momentary shock-load capacity

    • Low backlash and extended operational life
