Built for machinery builders, integrators, and maintenance teams that need compact pneumatic rotary power, the Cleco A6R335M reversible axial piston air motor delivers 1.9 HP with a 1,030 RPM free speed and 37 ft-lbs stall torque. An axial piston air motor uses piston-driven air power to produce strong torque in a compact package, making this model useful for driving mixers, conveyors, hoists, winches, pumps, and other equipment where an electric motor may not be the preferred power source. The rear exhaust configuration helps direct spent air away from the work area, while reversible operation supports equipment that must run in both directions.With a 3.4:1 gear ratio, 535 RPM at maximum horsepower, and 62 SCFM air consumption, the A6R335M is suited to applications requiring controlled pneumatic drive power rather than high-speed direct-drive output. Its keyed spindle provides a positive mechanical connection for transmitting torque to compatible couplings, shafts, or driven components.Type: Axial Piston Air Motor | Series: Cleco A6 Series | Model: A6R335M | Max Power: 1.9 HP / 1.42 kW | Free Speed: 1,030 RPM | RPM at Max HP: 535 RPM | Stall Torque: 37 ft-lbs / 50 Nm | Starting Torque: 27 ft-lbs / 37 Nm | Gear Ratio: 3.4:1 | Air Consumption: 62 SCFM | Air Inlet: 3/8″ NPTF | Control: Reversible | Exhaust: Rear | Mount: Face Mounting | Spindle: 1-1/8″ Keyed Spindle | Max Overhung Load at Stall: 1,000 lb / 454 kgFeatures:Axial piston air motor construction supports high torque output in a compact pneumatic drive package.1.9 HP maximum power provides usable drive force for machinery, fixtures, and equipment powered by compressed air.Reversible control allows the motor to operate in both directions for bidirectional drive applications.Rear exhaust directs air discharge away from the spindle side of the motor.Keyed spindle provides a positive mechanical connection for torque transfer to compatible drive components.3.4:1 gear ratio balances speed and torque for applications that need controlled rotary power.Rated performance is based on 90 PSI air pressure for consistent comparison across Cleco air motor models.Made in USA: Applications:Industrial automation and machinery building powering fixtures, indexing equipment, and compact rotary drive assemblies.Mixing and material handling systems driving mixers, agitators, conveyors, and transfer equipment where pneumatic power is preferred.Maintenance and MRO shops replacing or supplementing electric motors in wet, dirty, or air-powered work environments.Hoists, winches, and mechanical drive systems providing reversible air-powered rotation for controlled movement tasks.OEM equipment integration adding pneumatic drive capability to custom machines, production tooling, and process equipment.FAQs:Q: What is an axial piston air motor?A: An axial piston air motor uses compressed air to move pistons arranged along the motor axis, converting air pressure into rotary motion. This design is commonly selected when the application needs higher torque output than many small vane-style air motors can provide.Q: Can the Cleco A6R335M replace an electric motor?A: It may be used as a pneumatic alternative when the speed, torque, mounting, air supply, and spindle connection match the equipment requirements. Buyers should compare horsepower, RPM under load, stall torque, duty requirements, and mounting dimensions before replacing an electric motor.Q: What size air supply is needed?A: The listed air consumption is 62 SCFM, and Cleco rates performance at 90 PSI. The compressor and air lines should be sized to maintain the required pressure and flow during operation, especially in continuous-duty or high-load applications.Q: What does stall torque mean on this air motor?A: Stall torque is the torque available when the motor stops rotating under load. Air motors can generally stall without the same burnout risk associated with many electric motors, but the drive system and connected components still need to be sized for the load.Q: Why does maximum allowable speed matter?A: Cleco notes that these motors must be operated with sufficient load to prevent speed from exceeding the maximum allowable speed. This helps protect the motor and connected equipment from overspeed conditions. .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”; var b=a.querySelector(“.spec-accordion-toggle”),p=a.querySelector(“.spec-accordion-panel”);if(!b||!p)return; var u=false; function m(){return(a.getBoundingClientRect().width||window.innerWidth)
