Product Details

The compact and portable 16AM-HB20 (GM) series offers air motor operating speed and power output that can be adjusted to meet the precise needs of your application. Their 20:1 gear reducer is not only ideal for lower speed and higher torque applications, but they also can be stalled or overloaded for long periods without damaging the motor.
