Ingersoll Rand 8228-2B Reversible Air Power Motor is engineered to provide dependable pneumatic power for industrial applications requiring bidirectional operation, moderate output speed, and increased torque. Rated at 0.50 HP, this air power motor operates at a free speed of 3,200 RPM and incorporates double gear reduction to improve torque output while maintaining efficient rotary performance. Its reversible configuration allows clockwise and counterclockwise shaft rotation, making it well suited for OEM machinery, automated equipment, indexing systems, material handling equipment, and industrial processing applications where directional flexibility is required.
The 8228-2B develops 2.90 ft-lbs of stall torque, representing the maximum torque generated when the output shaft is prevented from rotating. The double gear reduction design provides enhanced torque multiplication over direct-drive motors while maintaining a higher operating speed, making this model suitable for industrial equipment requiring both speed and controlled torque.

FAQs:
- Q: Is the Ingersoll Rand 8228-2B reversible?
A: Yes. This model is designed to operate in both clockwise and counterclockwise directions. - Q: What is the benefit of double gear reduction?
A: Double gear reduction increases output torque while lowering output speed compared to a direct-drive motor, providing a balanced combination of speed and torque. - Q: What is the rated operating speed?
A: The manufacturer specifies a free speed of 3,200 RPM. - Q: What does the 2.90 ft-lbs stall torque specification indicate?
A: Stall torque is the maximum torque produced when the output shaft is prevented from rotating. It is intended as a performance reference and should not be considered a continuous operating torque. - Q: What should be verified before installing this motor?
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.
