Cleco 22M5071-50 Reversible Rotary Vane Air Motor | 0.7 HP | 500 RPM | 19.6 (ft-lbs) Stall Torque | Side Exhaust

Built for pneumatic drive systems that require moderate speed and reversible rotation, the Cleco 22M5071-50 is a 22 Series reversible rotary vane air motor delivering 0.7 HP at a free speed of 500 RPM. A rotary vane air motor uses sliding vanes within the motor chamber to convert compressed air into smooth shaft rotation, offering machinery builders a compact alternative to electric drive components for fixtures, auxiliary drives, and controlled mechanical motion applications.

This model provides 19.6 ft-lbs of stall torque, which is the torque available when the motor stops under load, and uses a 34.8:1 gear ratio to reduce output speed while increasing usable torque. The 1/2" keyed spindle creates a positive drive connection for compatible couplings, sprockets, pulleys, or driven components, while the side exhaust configuration helps direct exhaust air away from the work area or mounting surface during machine integration.

Features:

• 0.7 HP rotary vane motor supplies compact pneumatic power for machinery, fixtures, and auxiliary drive functions.
• Reversible operation supports clockwise and counter-clockwise rotation when connected to the appropriate pneumatic control circuit.
• 500 RPM free speed provides a faster output than lower-speed models in the same family while retaining torque-focused geared operation.
• 19.6 ft-lbs stall torque helps the motor handle load stops without the same burnout risk associated with many electric motors.
• 34.8:1 gear ratio balances output speed and torque for controlled mechanical drive applications.
• 1/2" keyed spindle provides a secure shaft connection for compatible hubs, pulleys, sprockets, or coupling assemblies.
• Flange and base mounting configuration supports machine integration where the motor must be fastened securely to a bracket, plate, or fixture.
• Side and rear 1/4" NPT air inlet options provide installation flexibility when routing compressed air lines.

Applications:

• Packaging and production machinery — driving indexing devices, small conveyors, adjustment mechanisms, and rotary machine functions.
• Fixture and tooling systems — powering clamps, turntables, jigs, and custom pneumatic motion systems requiring reversible rotation.
• Mixing and agitation equipment — supplying controlled shaft rotation where compressed air power is preferred over electrical drive components.
• Industrial maintenance and MRO — replacing worn air motors or building shop fixtures that require compact torque at moderate speed.
• OEM equipment builds — integrating pneumatic rotary power into equipment where stall tolerance, compact size, and air-powered control are important.

FAQs:

• Q: How is the 22M5071-50 different from the lower-speed 22M5070-50?
  A: The 22M5071-50 runs at 500 RPM free speed and has 19.6 ft-lbs of stall torque. The 22M5070-50 is slower at 330 RPM but provides higher stall torque, so the better choice depends on whether the application needs more speed or more torque.
• Q: What does reversible mean on this air motor?
  A: Reversible means the motor can rotate in either direction when properly plumbed and controlled. This is useful for mechanisms that must drive forward and backward, such as positioning fixtures, adjustment systems, or bidirectional machine functions.
• Q: What air supply does this motor require?
  A: The motor is rated at 29 SCFM air consumption and 90 PSI operating pressure. The air system should be sized to maintain that flow at the motor while accounting for hose length, fittings, regulators, and other equipment drawing from the same supply.
• Q: Can this motor be used as a replacement for an electric motor?
  A: It may be used in some applications where pneumatic power is preferred, but the speed, torque, shaft type, mounting pattern, duty cycle, and air supply must match the machine requirements. Always verify mechanical fit and performance before replacing an existing drive motor.
• Q: What does a 1/2" keyed spindle do?
  A: A keyed spindle uses a keyway to lock the shaft to a mating component such as a hub, coupling, pulley, or sprocket. This helps transmit torque more securely than a smooth shaft connection.
