PUMP DETAILS:
The Rexroth A2FM and AA2FM axial piston motors are high-efficiency hydraulic motors engineered for demanding industrial, mobile, and marine applications. Renowned for their durability, precision, and adaptability, these motors deliver reliable power in compact designs. This guide dives into their technical specifications, industry use cases, maintenaDisplacement Range:
A2FM Series: 10 cm³/rev to 500 cm³/rev (multiple sizes: A2FM10 to A2FM500).
AA2FM Series: 28 cm³/rev to 500 cm³/rev, optimized for higher torque and lower speed applications.
Pressure Rating:
Continuous operation: Up to 400 bar (5,800 psi).
Peak pressure: 450 bar (6,500 psi) for short-term loads.
Speed Range:
A2FM: Up to 4,000 rpm (varies by model).
AA2FM: Optimized for 100–3,600 rpm, ideal for high-torque scenarios.
Efficiency:
Mechanical efficiency >92%, volumetric efficiency >95% due to precision-machined components.
Mounting Options:
SAE, ISO, or custom flanges for compatibility with pumps, gearboxes, and drivetrains.
Fluid Compatibility:
Compatible with mineral oils, HLP, HETG, and HEES biodegradable fluids.
Maintenance & Troubleshooting Tips
Fluid Maintenance:
Use ISO 4406 Class 18/16/13 or cleaner oil; monitor moisture and particle contamination.
Seal Inspections:
Replace shaft seals every 5,000 hours or if leakage exceeds 10 drops/minute.
Bearing Lubrication:
Grease bearings annually with Rexroth-recommended lubricants (e.g., Shell Gadus S2).
Overheating Prevention:
Ensure adequate cooling; avoid sustained operation above 90°C (194°F).
