Cleco A2R304M A2 Series Reversible Axial Piston Air Motor | 0.6 HP | 200 RPM | 48 (ft-lbs) Stall Torque | Rear Exhaust

When a reversible pneumatic drive needs a slower output speed with stronger stall capability, the Cleco A2R304M A2 Series Reversible Axial Piston Air Motor delivers 0.6 HP at 200 RPM. Its axial piston design uses piston-driven compressed air to create smooth rotary motion, giving machine builders, maintenance teams, and pneumatic system integrators a compact drive option for equipment that must start, stop, reverse, or tolerate stalled-load conditions.

The A2R304M is configured with a 7/8" keyed spindle, rear exhaust, and 48 ft-lbs stall torque, making it a lower-speed, higher-torque option within the Cleco A2 Series. The 23.8:1 gear ratio reduces output speed while increasing torque at the spindle, while the keyed shaft provides a positive drive connection for compatible couplings, pulleys, sprockets, or other driven components.

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 paired with the proper pneumatic control arrangement.
• 0.6 HP / 0.45 kW output gives OEMs and maintenance teams a compact air-powered alternative to an electric motor package.
• 200 RPM free speed supports lower-speed rotary motion where torque and control are more important than fast output.
• 48 ft-lbs stall torque helps the motor handle load resistance during starting, holding, reversing, or stalled-load conditions.
• 23.8:1 gear ratio reduces speed while increasing torque at the output spindle compared with faster A2 Series configurations.
• 7/8" keyed spindle provides a positive mechanical drive interface for compatible couplings, pulleys, sprockets, and driven components.
• Rear exhaust routes spent air away from the spindle area to help simplify machine layout and air discharge routing.

Applications:

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

FAQs:

• Q: How does the A2R304M compare with faster A2 Series models?
  A: The A2R304M runs at 200 RPM and provides 48 ft-lbs stall torque, so it is better suited for lower-speed applications that need stronger output force. Faster A2 Series models may be a better fit when rotational speed is more important than stall torque.
• Q: What does reversible operation mean?
  A: Reversible operation means the motor can rotate in either direction when installed with the correct pneumatic valve setup. This is useful for winding, positioning, feeding, and machinery functions that require forward and reverse motion.
• Q: What is stall torque on an air motor?
  A: Stall torque is the torque available when the output stops rotating because of load resistance. The A2R304M is rated at 48 ft-lbs stall torque, which helps buyers compare it against other A2 Series models for starting force and stalled-load tolerance.
• Q: Why use 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 can also be useful in pneumatic equipment 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, sprockets, pulleys, or other driven components. The keyway helps transfer torque through a positive mechanical connection rather than relying only on friction clamping.
