Ingersoll Rand 8618-A Non-Reversible Multi-Vane Air Motor | Planetary Gear | 0.10 HP | 25,000 RPM | 0.10 (ft-lbs) Stall Torque | Single Gear Reduction

Designed for machinery and production equipment requiring very high rotational speed from a compact pneumatic drive, the Ingersoll Rand 8618-A Non-Reversible Multi-Vane Air Motor delivers 0.10 HP with a 25,000 RPM free speed. Its 3/8"-24 threaded spindle provides a defined connection for compatible driven components, while the single gear reduction supports the motor's high-speed output configuration.

At maximum horsepower, the 8618-A operates at 13,000 RPM and produces 0.04 lb-ft (0.05 Nm) of torque, with stall torque rated at 0.10 lb-ft (0.1 Nm). Free-speed air consumption is 9.5 SCFM (4.5 L/s), giving equipment designers an important requirement for sizing the compressed-air supply to the motor.

Made in USA: 

Applications:

• Production machinery requiring high-speed pneumatic rotary output.
• Automation equipment and fixtures designed for single-direction operation.
• Mechanical systems designed around a 3/8"-24 threaded spindle connection.
• Equipment where high rotational speed and relatively low torque match the driven load requirements.
• Compressed-air-powered machinery requiring a compact, lightweight motor configuration.

FAQs:

• Q: What is the free speed of the Ingersoll Rand 8618-A?
  A: The 8618-A has a free speed of 25,000 RPM. At maximum horsepower, the manufacturer lists a load speed of 13,000 RPM.
• Q: How much torque does the 8618-A produce?
  A: Torque output at maximum horsepower is 0.04 lb-ft (0.05 Nm), while stall torque is rated at 0.10 lb-ft (0.1 Nm).
• Q: What spindle does the 8618-A use?
  A: The motor uses a 3/8"-24 threaded spindle. The driven component and mounting arrangement should be compatible with this spindle specification.
• Q: How much compressed air does the 8618-A consume?
  A: Air consumption at free speed is specified at 9.5 SCFM (4.5 L/s). This value should be considered when sizing the air supply for the installation.
• Q: Is the 8618-A intended for high-torque or high-speed applications?
  A: The specifications characterize the 8618-A as the high-speed configuration among the non-reversible 0.10 HP models shown in the manufacturer table. Its 25,000 RPM free speed is paired with lower torque output than the slower geared models, so the driven equipment should be matched to these speed and torque characteristics.
