    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
