Ingersoll Rand 7812-1B Non-Reversible Air Power Motor is engineered to provide dependable pneumatic rotary power for industrial equipment requiring maximum output torque with controlled low-speed operation. Delivering 0.85 HP and a free speed of 350 RPM, this air motor features a double gear reduction that efficiently converts rotational speed into substantial output torque. It is an excellent choice for OEM machinery, industrial processing systems, material handling equipment, automated production machinery, conveyors, and other compressed-air powered applications where high rotary force and reliable single-direction operation are required.
The 7812-1B develops a 55.00 lb-ft stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. Its non-reversible configuration provides consistent one-direction operation, while the double-stage gear reduction delivers enhanced torque for demanding industrial applications that require controlled speed and dependable performance.

FAQs:
- Q: Is the Ingersoll Rand 7812-1B reversible?
A: No. This model is a non-reversible air motor designed for continuous rotation in one direction. - Q: What is the benefit of double gear reduction?
A: Double gear reduction uses two reduction stages to substantially lower output speed while increasing available output torque, making it suitable for demanding industrial applications that require high rotary force. - Q: What is the rated free speed?
A: The manufacturer specifies a free speed of 350 RPM. - Q: What does the stall torque rating indicate?
A: Stall torque is the maximum torque the motor develops when the output shaft is prevented from rotating under load. - Q: What should be verified before installation?
A: Confirm horsepower, free speed, rotation direction, gear reduction, shaft dimensions, mounting arrangement, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog before installation.
