Cleco A2R303M A2 Series Reversible Axial Piston Air Motor | 0.6 HP | 345 RPM | 28 (ft-lbs) Stall Torque | Rear Exhaust

When a reversible pneumatic drive needs a lower output speed with stronger stall force, the Cleco A2R303M A2 Series Reversible Axial Piston Air Motor delivers 0.6 HP power at 345 RPM. Its axial piston design uses piston-driven compressed air to produce smooth rotary motion, giving machine builders and maintenance teams a compact air-powered option for equipment that must start, stop, reverse, or tolerate stalled-load conditions.

The A2R303M is configured with a 7/8" keyed spindle, rear exhaust, and 28 ft-lbs stall torque, making it a slower and stronger A2 Series option than higher-speed models in the same family. The keyed spindle provides a positive drive connection for compatible couplings, sprockets, pulleys, or other driven components, while rear exhaust directs spent air away from the spindle area to help simplify installation routing.

Type: Reversible Axial Piston Air Motor | Series: A2 Series | Model: A2R303M | Spindle Type: Keyed | Spindle Size: 7/8" | Power: 0.6 HP / 0.45 kW | Free Speed: 345 RPM | Stall Torque: 28 ft-lbs | Control: Reversible | Exhaust: Rear

Features:

• Axial piston air motor construction provides smooth pneumatic rotary power for machinery, fixtures, and integrated drive systems.
• Reversible operation supports clockwise and counterclockwise output rotation when used with the proper pneumatic controls.
• 0.6 HP / 0.45 kW output offers compact air-powered drive capability for industrial equipment and OEM machine builds.
• 345 RPM free speed supports controlled rotary motion where higher torque is more important than fast output speed.
• 28 ft-lbs stall torque helps the motor handle load resistance during starting, holding, or stalled-load conditions.
• 7/8" keyed spindle provides a positive mechanical drive interface for compatible couplings, pulleys, sprockets, and driven components.
• Rear exhaust directs spent air away from the front spindle area to support cleaner installation routing in equipment layouts.
• Pneumatic motor design can stall under load without the same burnout risk associated with many electric motors.

Applications:

• Industrial automation and machinery — driving reversible fixtures, indexing mechanisms, compact rotary assemblies, and pneumatic equipment drives.
• Material handling systems — powering rollers, feed mechanisms, take-up devices, and small conveyor functions where controlled motion is required.
• Mixing and process equipment — supplying moderate low-speed rotary power for light agitation, stirring, or process-driven machinery.
• Plant maintenance and MRO — replacing or specifying air-powered rotary motion in systems exposed to frequent starts, stops, and load changes.
• OEM machine building — integrating a reversible pneumatic motor where keyed output, stall tolerance, and rear exhaust routing support the machine layout.

FAQs:

• Q: How does the A2R303M differ from faster A2 Series models?
  A: The A2R303M runs at 345 RPM and provides 28 ft-lbs stall torque, so it is better suited for applications that need more torque at a lower output speed. Faster A2 Series models may be a better fit when speed is more important than stall force.
• Q: What does reversible mean on this Cleco air motor?
  A: Reversible means the motor can rotate in either direction when installed with the correct pneumatic control valve arrangement. This is useful for winding, positioning, feeding, and other machinery functions that require forward and reverse motion.
• Q: What is stall torque used for?
  A: Stall torque is the torque available when the motor is stopped by load resistance. The 28 ft-lbs rating helps buyers compare this model against other A2 Series motors for starting force, holding force, and stalled-load tolerance.
• Q: Why choose an air motor instead of an electric motor?
  A: Air motors are often selected where frequent starts, stops, reversing, variable speed control, or stall tolerance are important. They are also useful in pneumatic systems where compressed air is already available at the machine.
• Q: What does the 7/8" keyed spindle connect to?
  A: The keyed spindle connects to compatible couplings, pulleys, sprockets, or other driven components. The keyway helps transfer torque through a positive mechanical connection rather than relying only on clamping friction.
