Cleco 22M5070-50 Reversible Rotary Vane Air Motor | 0.7 HP | 330 RPM | 28.4 (ft-lbs) Stall Torque | Side Exhaust

Built for low-speed drive applications that need reversible rotation and controlled torque, the Cleco 22M5070-50 is a 22 Series reversible rotary vane air motor with 0.7 HP output and 330 RPM free speed. Rotary vane air motors use sliding vanes inside the motor chamber to convert compressed air into smooth rotary motion, making them useful for fixtures, light machinery drives, mixing equipment, indexing devices, and other pneumatic automation tasks where electric motor replacement is being considered.

With 28.4 ft-lbs stall torque, a 50.4:1 gear ratio, and reversible control, this model is suited for applications that need torque multiplication at lower output speed rather than high-speed rotation. The 1/2" keyed spindle provides a positive mechanical drive connection for couplings, sprockets, pulleys, or other compatible driven components, while the side exhaust configuration helps route exhaust air away from the mounting area when installed in machinery or a fixture.

Features:

• 0.7 HP rotary vane motor provides compact pneumatic power for fixture-driven and machine-mounted applications.
• Reversible operation supports clockwise and counter-clockwise rotation where bidirectional drive control is required.
• 330 RPM output speed supports controlled low-speed rotation for torque-focused tasks instead of high-speed air tool operation.
• 28.4 ft-lbs stall torque allows the motor to stop under load without the same burnout risk associated with many electric motors.
• 50.4:1 gear ratio multiplies torque while reducing output speed for controlled mechanical drive applications.
• 1/2" keyed spindle creates a positive drive connection for compatible couplings, pulleys, sprockets, and driven components.
• Side and rear 1/4" NPT air inlet options give installers flexibility when routing compressed air lines into the motor.
• Standard equipment includes a hex socket screw for closure of the unused inlet and a flush fitting for gear lubrication.

Applications:

• Industrial automation and fixtures — driving indexed mechanisms, clamps, rotary fixtures, and machine-mounted devices that require reversible pneumatic motion.
• Mixing and agitation systems — providing low-speed rotational drive where compressed air power is preferred over electric drive components.
• Conveyor and packaging equipment — powering small drive functions, adjustment systems, and auxiliary mechanisms in production environments.
• Maintenance and MRO builds — replacing or specifying compact air-powered drive units for custom shop equipment and repair fixtures.
• OEM machinery integration — fitting into equipment designs where compact size, stall tolerance, and reversible rotation are important selection factors.

FAQs:

• Q: What does stall torque mean on this Cleco air motor?
  A: Stall torque is the turning force available when the motor stops under load. For this model, the stall torque is 28.4 ft-lbs, which helps buyers compare the motor’s low-speed pulling capability for fixtures, drives, and machinery.
• Q: Can the 22M5070-50 run in both directions?
  A: Yes. This is a reversible air motor, so it can operate clockwise or counter-clockwise when properly connected and controlled in the pneumatic circuit.
• Q: What air supply is required?
  A: The manufacturer lists air consumption at 29 SCFM and rates performance at 90 PSI. The compressed air system should be sized to deliver that airflow continuously at the motor while allowing for line losses and any other tools or equipment using the same supply.
• Q: What is a keyed spindle?
  A: A keyed spindle has a slot for a key that helps lock the spindle to a mating hub, coupling, pulley, or sprocket. This provides a more secure mechanical drive connection than a smooth shaft in torque-transmitting applications.
• Q: Is this an electric motor replacement?
  A: It can be used in some applications where a pneumatic drive is preferred, but mounting, torque, speed, air supply, duty cycle, and control requirements must all match the equipment. Verify fit and performance requirements before replacing an existing electric motor.
