Designed for machinery and equipment requiring controlled pneumatic rotary power, the Ingersoll Rand 8616-A Non-Reversible Multi-Vane Air Motor delivers 0.10 HP with a 1,000 RPM free speed. Its 3/8"-24 threaded spindle provides a defined connection for compatible driven components, while double gear reduction supports the lower-speed, higher-torque characteristics of this model.
At maximum horsepower, the 8616-A operates at 500 RPM and produces 1.05 lb-ft (1.4 Nm) of torque, with stall torque reaching 1.8 lb-ft (2.4 Nm). Air consumption at free speed is 9.5 SCFM (4.5 L/s), an important consideration when sizing the compressed-air supply for continuous equipment operation.

Features:
- Multi-vane pneumatic design provides rotary power for compatible machinery, fixtures, and equipment.
- 1,000 RPM free speed and 500 RPM load speed at maximum horsepower provide a controlled operating range for lower-speed applications.
- Double gear reduction supports increased torque output while reducing rotational speed.
- 3/8"-24 threaded spindle provides a threaded mechanical interface for compatible driven components.
- Non-reversible configuration provides single-direction rotary operation.
- 1.8 lb-ft (2.4 Nm) stall torque indicates the torque developed as motor speed approaches zero.
- 0.90 lb (0.40 kg) weight supports integration into equipment where motor weight is an important design consideration.
- 9.5 SCFM (4.5 L/s) free-speed air consumption provides a reference for compressed-air system sizing.

Applications:
- Production machinery requiring controlled pneumatic rotary power.
- Automation equipment and fixtures designed for single-direction motor operation.
- Mechanical systems compatible with a 3/8"-24 threaded spindle connection.
- Equipment requiring lower operating speed with increased torque from a geared air motor.
- Compressed-air-powered machinery where the specified speed and torque characteristics match the driven load.
FAQs:
- Q: What spindle connection does the Ingersoll Rand 8616-A use?
A: The 8616-A uses a 3/8"-24 threaded spindle. The mating component should be compatible with this spindle size and thread configuration. - Q: What torque does the 8616-A produce under load?
A: At maximum horsepower, torque output is 1.05 lb-ft (1.4 Nm). Stall torque is rated at 1.8 lb-ft (2.4 Nm). - Q: What is the loaded operating speed of the 8616-A?
A: The motor has a 1,000 RPM free speed and operates at 500 RPM at maximum horsepower. The loaded value is particularly useful when matching the motor to driven equipment. - Q: How much compressed air does the 8616-A consume?
A: The manufacturer specifies 9.5 SCFM (4.5 L/s) at free speed. The air system should be sized to provide adequate airflow for the intended installation. - Q: What is the difference between the 8616-A and 8610-A?
A: The supplied manufacturer table shows the same power, speed, torque, airflow, weight, and double gear reduction for both models. The key difference is the spindle: the 8616-A uses a 3/8"-24 threaded spindle, while the 8610-A uses a 3/8" keyed spindle.
