Ingersoll Rand 7542-C Non-Reversible Air Power Motor provides high-speed pneumatic rotary output for machinery requiring single-direction operation. Rated at 0.25 HP and 20,000 RPM, this model uses a single gear reduction configuration to deliver its specified output characteristics. The non-reversible design is intended for equipment where the driven mechanism operates in one rotational direction and does not require bidirectional control.
The 7542-C develops 0.22 lb-ft stall torque, which represents the torque produced when the applied load prevents the motor output from rotating. Its combination of high 20,000 RPM output, 0.25 HP power rating, single gear reduction, and specified stall torque provides machine builders and maintenance professionals with key selection criteria when evaluating this air power motor for compatible OEM machinery or replacement installations.

Made in USA: 
Applications:
- OEM machinery requiring high-speed pneumatic rotary power.
- Production equipment designed for single-direction motor operation.
- Machine-building applications compatible with the motor's 20,000 RPM output and 0.25 HP rating.
- Compressed-air-powered mechanisms where a single gear reduction configuration matches the equipment requirements.
- MRO replacement installations where the 7542-C specifications and mechanical interfaces match the existing motor.
FAQs:
- Q: Is the Ingersoll Rand 7542-C reversible?
A: No. The 7542-C is specified as a non-reversible air power motor for compatible equipment requiring rotation in one direction. - Q: What is the output speed of the 7542-C?
A: The supplied product information specifies an output speed of 20,000 RPM. - Q: What gear reduction configuration does the 7542-C use?
A: This model is specified with single gear reduction. The reduction configuration should be matched to the requirements of the driven equipment when selecting or replacing an air motor. - Q: What is the stall torque rating of the 7542-C?
A: The specified stall torque is 0.22 lb-ft. Stall torque represents the torque developed when the applied load prevents the motor output from rotating. - Q: What should be verified before installing the 7542-C?
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.
