The A2FE63 series axial piston hydraulic motors are fixed-displacement motors designed for high-pressure hydrostatic drives in open or closed circuits. These motors feature a spherical piston design with robust construction, providing reliable performance in demanding industrial and mobile applications.

• High Pressure Operation: Continuous operating pressure up to 32 MPa, with peak pressure tolerance up to 31.5 MPa
• Spherical Piston Design: Self-aligning piston and cylinder block interface reduces wear and enhances efficiency
• Compact Installation: Central flange mounting allows for space-saving integration
• High Power Density: Optimized design delivers high torque output in a compact package
• Low Noise Operation: Optimized flow characteristics ensure quiet performance
• Versatile Circuit Compatibility: Suitable for both open and closed hydraulic circuits
• Long Service Life: Durable construction with high-quality materials

• VZL027-S: Standard open circuit configuration
• VAL027-S: Alternative porting arrangement
• VZL027F-SK: Flange-mounted with special sealing
• VZAL027F-SK: Enhanced sealing and porting configuration

• Mobile Machinery: Excavators, wheel loaders, cranes
• Industrial Equipment: Presses, conveyors, material handling systems
• Marine Applications: Winches, propulsion systems
• Construction Equipment: Drilling rigs, compactors
• Agricultural Machinery: Tractors, harvesters

• Verify motor shaft rotates freely
• Check for any visible damage
• Ensure mounting surface is clean and flat
• Confirm hydraulic connections match port sizes

1. Alignment: Ensure motor shaft aligns with driven equipment without imposing radial or axial loads
2. Bolting: Use evenly tightened bolts (recommended torque: 80-100 Nm for M12 bolts)
3. Coupling: Use flexible coupling to accommodate minor misalignments
4. Port Connections: Use appropriate seals and ensure connections are leak-free

• Fluid Cleanliness: NAS 1638 Class 8 or better
• Filtration: Use filters with β₍₁₀₎ ≥ 100
• Oil Viscosity: 27-43 mm²/s at operating temperature
• System Flushing: Flush system before motor installation

1. Fill system with recommended hydraulic fluid
2. Vent air from system
3. Start system at low pressure and check for leaks
4. Gradually increase pressure to operating level
5. Monitor temperature during initial operation

• Daily: Check for leaks, unusual noise, or vibration
• Weekly: Check oil level and condition
• Every 500 hours: Check filter condition
• Every 1000-3000 hours: Change hydraulic oil (depending on operating conditions)
• Every 2000 hours: Check mounting bolts and connections

The A2FE63 models have a displacement of 63 cm³/rev, while A2FE56 models are 56 cm³/rev. This means A2FE63 motors can deliver higher torque at the same pressure, making them suitable for applications requiring more power.

The suffixes indicate specific configuration differences. Always refer to the specific product datasheet for exact configuration details, as suffix meanings can vary.

Yes, A2FE63 series motors are suitable for both open and closed hydraulic circuits. However, specific model configurations may be optimized for one circuit type.

The recommended continuous operating speed range is 100-2800 rpm. Operating above this range may cause excessive wear or damage.

Replacement parts should be sourced using the complete model number (including all suffixes) and serial number if available. Always use genuine parts from authorized distributors.

These products typically carry a standard warranty period of 12 months from date of installation or 18 months from date of shipment (whichever comes first), subject to proper installation and operation within specified parameters.
