Ingersoll Rand 8276-3A Non-Reversible Air Power Motor is engineered to deliver dependable pneumatic rotary power for industrial equipment requiring maximum output torque with controlled low-speed operation. Producing 0.90 HP with a free speed of 300 RPM, this air motor incorporates a triple gear reduction that further increases output torque while reducing shaft speed for demanding industrial applications. Its non-reversible configuration provides reliable single-direction operation, making it an excellent choice for OEM machinery, industrial processing systems, material-handling equipment, conveyors, and other compressed-air-powered installations where slow, controlled motion and high torque are required.
The 8276-3A develops a 60.00 ft-lbs stall torque, representing the maximum torque produced when the output shaft is prevented from rotating. The triple-stage gear reduction provides enhanced torque multiplication compared to lower reduction ratios, delivering dependable performance for applications that require substantial rotary force at reduced operating speeds.

FAQs:
- Q: Is the Ingersoll Rand 8276-3A 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 reducing output speed, making it well suited for applications requiring slow, controlled, high-torque operation. - Q: What is the rated free speed?
A: The manufacturer specifies a free speed of 300 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.
