Ingersoll Rand 8274-3A Reversible Air Power Motor is engineered to provide dependable pneumatic rotary power for industrial applications requiring high output torque, controlled low-speed operation, and bidirectional capability. Delivering 0.65 HP with a free speed of 200 RPM, this air motor features a triple gear reduction that maximizes torque multiplication while significantly reducing output speed. Its reversible configuration enables both clockwise and counterclockwise rotation, making it well suited for OEM machinery, industrial processing equipment, indexing systems, heavy-duty material handling equipment, conveyors, and other compressed-air powered applications requiring reliable directional control.
The 8274-3A develops a 52.00 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. The triple-stage gear reduction delivers enhanced rotary force for demanding industrial applications that require slow, controlled movement together with dependable reversing capability.
