Ingersoll Rand 8276-2A Non-Reversible Air Power Motor is engineered to provide dependable pneumatic rotary power for industrial equipment requiring exceptionally high output torque with controlled low-speed operation. Delivering 0.90 HP with a free speed of 350 RPM, this air motor features a double gear reduction that efficiently multiplies output torque while reducing rotational speed. Its non-reversible configuration provides reliable single-direction operation, making it an excellent solution for OEM machinery, material-handling systems, industrial processing equipment, conveyors, and other compressed-air-powered applications where high rotary force is essential.
The 8276-2A develops a stall torque of 50.00 ft-lbs, representing the maximum torque produced when the output shaft is prevented from rotating. The double-stage gear reduction delivers substantial rotary force while maintaining smooth, controlled performance, making this motor well suited for demanding industrial applications requiring dependable low-speed operation and increased torque.

FAQs:
- Q: Is the Ingersoll Rand 8276-2A reversible?
A: No. This model is a non-reversible air motor designed for continuous operation in one direction. - Q: What is the advantage of double gear reduction?
A: Double gear reduction uses two reduction stages to substantially lower output speed while increasing available output torque, making it ideal for applications requiring controlled, high-torque performance. - Q: What is the rated free speed?
A: The manufacturer specifies a free speed of 350 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.
