Ingersoll Rand 17RB078 Spur Gear Reversible Multi-Vane Air Motor is designed to deliver dependable pneumatic rotary power for industrial applications requiring reversible operation, very low operating speed, and exceptionally high torque output. This air motor provides 2.2 HP with a free speed of 69 RPM. Its spur gear and multi-vane configuration provides a pneumatic drive solution for compatible OEM machinery, production equipment, and rotary applications where bidirectional operation and controlled low-speed output are required.
The 17RB078 provides 327 ft-lbs starting torque, offering substantial breakaway capability to initiate rotation from rest, and 545 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. The reversible design allows operation in both rotational directions, while the 69 RPM free speed provides a very low-speed option for applications requiring exceptionally high torque capability.
