Ingersoll Rand 7537-C Non-Reversible Air Power Motor provides high-speed pneumatic rotary output for machinery requiring consistent single-direction operation. Rated at 0.25 HP and 20,000 RPM, this model uses a single gear reduction to deliver its specified output characteristics. Its non-reversible configuration is intended for equipment where the driven mechanism operates in one rotational direction without requiring forward-and-reverse functionality.
The 7537-C develops 0.22 lb-ft stall torque, representing the torque produced when the applied load prevents the motor output from rotating. The combination of 20,000 RPM output, 0.25 HP power, single gear reduction, and specified stall torque gives OEM designers, machine builders, and maintenance professionals key selection data for evaluating this air power motor for compatible machinery or a replacement pneumatic drive.
Type: Air Power Motor | Model: 7537-C | Rotation: Non-Reversible | Power: 0.25 HP | Speed: 20,000 RPM | Stall Torque: 0.22 lb-ft | Gear Reduction: Single
Features:
- Pneumatic motor configuration provides rotary output from a compatible compressed-air supply.
- Single gear reduction provides the specified output configuration for compatible machinery.
- 0.25 HP rating gives equipment designers a defined power specification for matching the motor to the driven mechanism.
- 20,000 RPM output supports machinery requiring high-speed pneumatic rotary motion.
- 0.22 lb-ft stall torque provides a load reference when evaluating the motor against application requirements.
- Non-reversible configuration is suited to equipment designed for consistent single-direction rotation.
Made in USA: 
Applications:
- OEM machinery requiring high-speed pneumatic rotary power in one direction.
- Production equipment compatible with a 20,000 RPM motor output.
- Machine-building applications designed around the motor's specified horsepower, speed, and stall torque.
- Compressed-air-powered mechanisms where a single gear reduction configuration matches the required drive arrangement.
- MRO replacement installations where the 7537-C performance ratings and mechanical interfaces match the existing motor.
FAQs:
- Q: Does the Ingersoll Rand 7537-C provide reversible operation?
A: No. The 7537-C is specified as a non-reversible air power motor and is intended for compatible equipment requiring rotation in one direction. - Q: What is the output speed of the 7537-C?
A: The specified output speed is 20,000 RPM. - Q: Does the 7537-C use single or double gear reduction?
A: The 7537-C is specified with single gear reduction. This configuration should be matched to the requirements of the driven equipment when selecting or replacing an air motor. - Q: How much stall torque does this air power motor provide?
A: The 7537-C is rated at 0.22 lb-ft stall torque. Stall torque represents torque developed when the applied load prevents the motor output from rotating. - Q: What should be checked before specifying the 7537-C for a machine?
A: Confirm that the application requires 0.25 HP, 20,000 RPM output, 0.22 lb-ft stall torque, non-reversible operation, and single gear reduction. Shaft, mounting, dimensional, and compressed-air requirements should also be verified against the manufacturer catalog before installation.
