    Speed Reducers for Position- and Speed-Control Motors

    Pair these speed reducers with stepper and servo motors in position- and speed-control applications. Helical gears provide exact positioning and smoother travel than our other speed reducers. Attach to a motor to transmit motion parallel to the motor shaft while reducing speed and increasing torque.
    With 1 Output Shaft

    IP65 Enclosure Rating—They meet IP65 for protection from washdowns.
    Radial Load Capacity—Radial loads are loads that are perpendicular to the shaft. They’re commonly caused by components attached to shaft, such as pulleys and sprockets.
