Ingersoll Rand 8228-13B Reversible Air Power Motor is engineered for demanding industrial applications that require maximum pneumatic torque, extremely low operating speed, and dependable bidirectional performance. Rated at 0.50 HP, this air power motor operates at a free speed of 50 RPM and utilizes triple gear reduction to maximize torque multiplication while delivering smooth, controlled rotary motion. Its reversible configuration allows both clockwise and counterclockwise shaft rotation, making it well suited for OEM machinery, heavy-duty positioning systems, indexing equipment, material handling systems, and industrial automation applications where controlled movement in either direction is essential.
The 8228-13B develops 60.00 ft-lbs of stall torque, representing the maximum torque generated when the output shaft is prevented from rotating. The triple gear reduction system delivers exceptional rotational force at extremely low speeds, making this model an excellent solution for heavy-load industrial equipment requiring precise motion and reliable pneumatic power.

FAQs:
- Q: Is the Ingersoll Rand 8228-13B reversible?
A: Yes. This model is designed to operate in both clockwise and counterclockwise directions. - Q: What is the advantage of triple gear reduction?
A: Triple gear reduction provides maximum torque multiplication while significantly reducing output speed, making it suitable for applications requiring substantial rotational force and precise low-speed operation. - Q: What is the rated operating speed?
A: The manufacturer specifies a free speed of 50 RPM. - Q: What does the 60.00 ft-lbs stall torque specification indicate?
A: Stall torque is the maximum torque produced when the output shaft is prevented from rotating. It serves as a performance reference and should not be interpreted as continuous operating torque. - Q: What should be verified before installation?
A: Confirm horsepower, operating speed, rotation direction, gear reduction, shaft dimensions, mounting arrangement, and compressed-air requirements using the Ingersoll Rand Air Motor Catalog before installation.
