When a machine or fixture needs controlled pneumatic rotary power with stronger low-speed torque, the Cleco A6R307M reversible axial piston air motor delivers 1.9 HP, 605 RPM free speed, and 64 ft-lbs stall torque. An axial piston air motor uses piston-driven compressed air power to create rotary motion, making this model a practical choice for equipment that requires air-powered rotation instead of an electric motor. The rear exhaust configuration directs discharge air away from the spindle side, while reversible operation supports machinery that must drive in both directions.With a 5.8:1 gear ratio and 315 RPM at maximum horsepower, the A6R307M trades higher free speed for greater torque capacity than faster models in the same Cleco A6 Series. Its 1-1/8″ keyed spindle provides a positive mechanical drive connection for compatible couplings, shafts, and driven components, while face mounting helps simplify integration into OEM equipment, process machinery, and plant-built fixtures.Type: Axial Piston Air Motor | Series: Cleco A6 Series | Model: A6R307M | Max Power: 1.9 HP / 1.42 kW | Free Speed: 605 RPM | RPM at Max HP: 315 RPM | Stall Torque: 64 ft-lbs / 87 Nm | Starting Torque: 48 ft-lbs / 65 Nm | Gear Ratio: 5.8:1 | Air Consumption: 62 SCFM / 1.76 m3/min | Air Inlet: 3/8″ NPTF | Control: Reversible | Exhaust: Rear | Mount: Face Mounting | Spindle: 1-1/8″ Diameter Keyed Spindle | Weight: 27 lbs / 12.2 kg | Max Overhung Load at Stall: 1,000 lbs / 454 kgFeatures:Axial piston motor construction provides strong torque output for air-powered machinery and mechanical drive systems.Reversible operation supports bidirectional equipment movement, indexing, winding, and positioning tasks.Rear exhaust helps route discharge air away from the driven end of the motor.5.8:1 gear ratio increases torque capacity while keeping output speed suitable for controlled rotary drive applications.1-1/8″ diameter keyed spindle creates a positive mechanical connection for transmitting torque to compatible components.Face mounting configuration supports fixed installation on machinery, fixtures, and custom equipment.Rated performance is based on 90 PSI air pressure for consistent comparison across Cleco A6 Series air motors.Made in USA: Applications:OEM machinery and automation powering rotating fixtures, indexing mechanisms, and compact air-driven assemblies.Material handling systems driving conveyors, turntables, winders, and transfer equipment where pneumatic power is preferred.Mixing and agitation equipment supplying reversible rotary motion for mixers, agitators, and process equipment.Industrial maintenance and MRO replacing or supplementing electric motors in air-powered plant systems and custom repair setups.Hoists, winches, and mechanical drive equipment providing controlled rotary power where torque and direction change are required.FAQs:Q: What type of air motor is the Cleco A6R307M?A: The A6R307M is a reversible axial piston air motor. Axial piston motors use compressed air acting on pistons to produce rotary output, which makes them useful for applications with heavier starting loads and controlled drive requirements.Q: How does the A6R307M compare with faster A6 Series models?A: The A6R307M runs at 605 RPM free speed and provides 64 ft-lbs of stall torque. Compared with higher-speed A6 models, it gives up speed to gain more torque for slower, stronger rotary drive applications.Q: What air supply should be planned for this motor?A: Cleco lists air consumption at 62 SCFM, with performance rated at 90 PSI. The compressor, regulator, hose, and piping should be sized to maintain adequate air volume and pressure at the motor during operation.Q: What does stall torque mean?A: Stall torque is the torque available when the motor is stopped under load. Air motors can generally tolerate stalling better than many electric motors, but the connected drive components must still be sized for the torque load.Q: Should this motor be run unloaded?A: No. Cleco notes that these motors must be operated with sufficient load to prevent speed from exceeding the maximum allowable speed shown on the performance curve. .spec-accordion{width:100%;max-width:1200px;margin:1em auto;font-family:”Montserrat”,Arial,sans-serif;box-sizing:border-box}.spec-accordion *{box-sizing:border-box}.spec-accordion-toggle{width:100%;display:flex;justify-content:center;align-items:center;position:relative;background:#444;color:#fff;border:0;padding:14px 48px;font-family:”Bai Jamjuree”,Arial,sans-serif;font-size:16px;font-weight:700;text-transform:uppercase;cursor:pointer;text-align:center}.spec-accordion-toggle::after{content:”+”;font-size:22px;position:absolute;right:18px}.spec-accordion.open .spec-accordion-toggle::after{content:””}.spec-accordion-panel{display:none!important;width:100%;padding:16px 0 0}.spec-accordion.open .spec-accordion-panel{display:block!important}.spec-accordion-panel[hidden],.spec-accordion:not(.open) .spec-accordion-panel{display:none!important}.spec-table-wrapper{width:100%;max-width:1200px;margin:0 auto;overflow-x:visible!important;overflow-y:visible}.spec-table{width:100%!important;max-width:1200px;min-width:0!important;margin:0 auto;border-collapse:collapse;table-layout:fixed;font-family:”Montserrat”,Arial,sans-serif;font-size:12px;color:#000}.spec-table th{background:#444;color:#fff;text-transform:uppercase;font-family:”Bai Jamjuree”,Arial,sans-serif;font-weight:700;font-size:11px;padding:8px 5px;border:1px solid #ddd;text-align:center;line-height:1.15;white-space:normal;overflow-wrap:anywhere;word-break:normal}.spec-table td{padding:6px 5px;border:1px solid #eee;text-align:center;line-height:1.15;white-space:normal;overflow-wrap:anywhere;word-break:normal}.spec-table .long-text{white-space:normal}.spec-table tbody tr:nth-child(even){background:#f7f7f7}.spec-table tbody tr:hover{background:#e5e5e5}.spec-table a{color:#0066cc;text-decoration:none;font-weight:600;background:transparent;padding:0;border-radius:0;box-shadow:none}.spec-table a:hover{text-decoration:underline}.group-row td{background:#444;color:#fff;font-family:”Bai Jamjuree”,Arial,sans-serif;font-weight:700;text-transform:uppercase;text-align:left}@media(max-width:640px){.spec-accordion,.spec-table-wrapper,.spec-table{width:100%;max-width:100%}.spec-accordion-toggle{font-size:14px;padding:13px 48px}}.spec-accordion.is-mobile-table .spec-table-wrapper{overflow-x:visible!important;overflow-y:visible}.spec-accordion.is-mobile-table .spec-table{width:100%;max-width:100%;min-width:0!important;border:0}.spec-accordion.is-mobile-table .spec-table thead{display:none!important}.spec-accordion.is-mobile-table .spec-table,.spec-accordion.is-mobile-table .spec-table tbody,.spec-accordion.is-mobile-table .spec-table tr,.spec-accordion.is-mobile-table .spec-table td{display:block;width:100%}.spec-accordion.is-mobile-table .spec-table tr{margin-bottom:14px;border:1px solid #ddd;background:#fff}.spec-accordion.is-mobile-table .spec-table tbody tr:nth-child(even),.spec-accordion.is-mobile-table .spec-table tbody tr:hover{background:#fff}.spec-accordion.is-mobile-table .spec-table th,.spec-accordion.is-mobile-table .spec-table td{white-space:normal!important}.spec-accordion.is-mobile-table .spec-table td{display:flex;justify-content:space-between;gap:14px;text-align:right;border:0;border-bottom:1px solid #eee;padding:10px 12px;font-size:13px;word-break:break-word}.spec-accordion.is-mobile-table .spec-table td::before{content:attr(data-label);font-weight:700;text-transform:uppercase;color:#444;text-align:left;flex:0 0 46%}.spec-accordion.is-mobile-table .spec-table td>a{word-break:break-word;background:transparent}.spec-accordion.is-mobile-table .group-row td{text-align:center;background:#444;color:#fff}.spec-accordion.is-mobile-table .group-row td::before{content:none} Available Variations and SpecificationsSKUMountSpindle TypeRPM at Max HPFree SpeedTorque StallWeightGear RatioLengthHorsepowerAir ConsumptionControl(RPM)(RPM)Ft-Lb | NmLbkgin | mmHp | kW(SCFM)A6R331MFace Mounting1 1/8 in Keyed Spindle54100370.0 | 5024319.533.6-119.06 | 4841.962ReversibleA6R333MFace Mounting1 1/8 in Keyed Spindle89170223.0 | 3024319.520.3-119.06 | 4841.962ReversibleA6R332MFace Mounting1 1/8 in Keyed Spindle152290130.0 | 1764319.511.9-119.06 | 4841.962ReversibleA6R307MFace Mounting1 1/8 in Keyed Spindle31560564.0 | 872712.25.8-115.88 | 4031.962ReversibleA6R335MFace Mounting1 1/8 in Keyed Spindle535103037.0 | 502712.23.4-115.88 | 4031.962ReversibleA6R308MFace MountingDiscontinued182035001.0 | 152712.21-115.88 | 4031.962Reversible (function(){ function initSpecAccordions(){ document.querySelectorAll(“.spec-accordion”).forEach(function(a){ if(a.dataset.specAccordionInit===”true”)return;a.dataset.specAccordionInit=”true”;
