Ingersoll Rand 8228-8B Reversible Air Power Motor is designed to provide dependable pneumatic rotary power for industrial applications requiring high torque, low-speed performance, and bidirectional operation. Delivering 0.50 HP at a free speed of 350 RPM, this air power motor features double gear reduction to maximize torque output while maintaining smooth and efficient operation. Its reversible configuration allows clockwise and counterclockwise shaft rotation, making it an excellent choice for OEM machinery, material handling systems, positioning equipment, conveyors, and automated production systems that require controlled movement in both directions.
The 8228-8B develops 25.00 ft-lbs of stall torque, representing the maximum torque generated when the output shaft is prevented from rotating. The double gear reduction design provides significant torque multiplication, enabling reliable performance in demanding industrial applications requiring substantial rotational force at reduced operating speeds.

FAQs:
- Q: Is the Ingersoll Rand 8228-8B reversible?
A: Yes. This model is designed to operate in both clockwise and counterclockwise directions. - Q: What is the advantage of double gear reduction?
A: Double gear reduction increases output torque while lowering operating speed, making the motor well suited for applications requiring greater rotational force at controlled speeds. - Q: What is the rated operating speed?
A: The manufacturer specifies a free speed of 350 RPM. - Q: What does the 25.00 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.
