Cleco MBW413M MB Series Radial Piston Air Motor | 5.5 HP | 540 RPM | 192 (ft-lbs) Stall Torque | Rear Exhaust

When a machine drive needs higher shaft speed without giving up the load-starting behavior of a piston motor, the Cleco MBW413M MB Series Radial Piston Air Motor delivers 5.5 HP with a 540 RPM free speed. Its radial piston design uses multiple pistons arranged around the crankshaft to generate strong rotary force at controlled speeds, making it a practical choice for mixers, conveyors, winches, and other equipment that may start under load. With 192 ft-lbs of stall torque, this model provides the locked-rotor torque capacity needed for demanding pneumatic drive applications, while the rear exhaust configuration helps route discharged air away from the work area.

The MBW413M sits in Cleco’s MB Series radial piston air motor family and uses a 1-1/2" keyed spindle for mechanical power transmission through compatible couplings, sprockets, pulleys, or driven components. Its 5.6:1 gear ratio balances speed reduction and torque multiplication, giving system designers a useful middle point between slower, higher-torque MB Series models and faster direct-drive pneumatic motors. This model is supplied without valving, allowing the air control package to be selected around the installation’s direction, control, and safety requirements.

Features:

• Radial piston air motor configuration provides strong starting torque for machinery that may begin rotation under load.
• 5.5 HP / 4.10 kW maximum power rating supports larger pneumatic drive applications in plant, process, and equipment systems.
• 540 RPM free speed offers a faster MB Series output option for applications that need more shaft speed than lower-RPM, higher-torque models.
• 192 ft-lbs stall torque helps the motor overcome resistance during startup, jam recovery, or high-load operating conditions.
• 5.6:1 gear ratio reduces motor speed while increasing usable output torque at the drive connection.
• 1-1/2" keyed spindle provides a positive mechanical drive interface for compatible couplings and driven components.
• Rear exhaust directs spent air away from the front of the motor, helping simplify machine layout and work-zone planning.
• Available reverse valve kit MAB70074 and single-direction valve 90A39 are listed for the MB Series; fitting 63J11 is also required with 90A39.

Applications:

• Process mixing and agitation systems where pneumatic power is preferred and moderate output speed is required.
• Conveyor drives and indexing equipment that need controlled rotary motion with strong startup capability.
• Winch, hoist, and reel drive assemblies using air power in production, maintenance, or field-service environments.
• Machine builders and integrators specifying a keyed-spindle air motor for mechanical drive connections.
• Industrial MRO teams replacing or supporting pneumatic drive motors on existing plant equipment.
• Oil and gas, marine, mining, and processing facilities where air motors are commonly selected for power, stall tolerance, and air-system compatibility.

FAQs:

• Q: What is the Cleco MBW413M used for?
  A: The MBW413M is used as a pneumatic rotary drive motor for equipment such as mixers, conveyors, winches, reels, and machinery fixtures. It is selected when the application needs air-powered rotation with 5.5 HP output and 192 ft-lbs of stall torque.
• Q: What does stall torque mean on this air motor?
  A: Stall torque is the torque available when the motor output is stopped under load. The MBW413M is rated at 192 ft-lbs of stall torque, which helps indicate its ability to start or resist high-load conditions without the same failure mode concerns as an electric motor.
• Q: Is this model supplied with valves?
  A: No. The MBW413M is listed with no valving, so the directional control, single-direction valve, reversing valve, and related fittings must be selected separately based on the machine design and operating sequence.
• Q: What is the difference between free speed and RPM at max HP?
  A: Free speed is the no-load speed of the motor. RPM at max HP is the speed where the motor reaches its maximum power output under load, which is often more useful when comparing motor performance for real equipment applications.
• Q: What air supply should be planned for this motor?
  A: The listed air consumption is 140 SCFM and the air inlet is 1" NPTF. The compressed air system, hoses, fittings, filtration, regulation, and lubrication should be sized to maintain the required flow and pressure at the motor during operation.
