Ingersoll Rand 8276-6A Non-Reversible Air Power Motor is engineered to deliver dependable pneumatic rotary power for industrial equipment requiring exceptional output torque at very low operating speeds. Producing 0.90 HP with a free speed of 50 RPM, this air motor incorporates a triple gear reduction that maximizes torque multiplication while significantly reducing output speed. Its non-reversible configuration provides reliable single-direction operation, making it an excellent choice for OEM machinery, heavy-duty material-handling systems, industrial processing equipment, indexing mechanisms, conveyors, and other compressed-air-powered applications where slow, controlled motion and maximum rotary force are essential.
The 8276-6A develops a 150.00 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. The triple-stage gear reduction provides substantial torque multiplication for demanding industrial applications requiring extremely low operating speeds without sacrificing output force.

FAQs:
- Q: Is the Ingersoll Rand 8276-6A reversible?
A: No. This model is a non-reversible air motor designed for continuous operation in one direction. - Q: What is the advantage of triple gear reduction?
A: Triple gear reduction uses three reduction stages to maximize torque multiplication while significantly lowering output speed, making it ideal for applications requiring extremely slow, controlled, high-torque operation. - Q: What is the rated free speed?
A: The manufacturer specifies a free speed of 50 RPM. - Q: What does the stall torque rating represent?
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.
