  • XB Cloidal Pin Wheel Gear Reducer

    XB Cloidal Pin Wheel Gear Reducer

    Cycloidal gear drives are unique and are still unsurpassed where drive technology is concerned. The cycloidal speed reducer is superior to traditional gear mechanisms, since it only operates with rolling force and is not exposed to shear forces. By comparison with gears with contact loads, Cyclo drives are more resistant and can absorb extreme shock loads by means of uniform load distribution over the power transmitting components. Cyclo drives and cyclo drive geared motors are characterized by their reliability, long service life and outstanding efficiency, even under difficult conditions.
