A2FE Series Hydraulic Motors
2 month ago
Product details
1. Model Breakdown (A2FE125/61W-VZL171)
• A2FE: Bosch Rexroth's axial-piston variable-displacement motor series code, indicating abent-axis designwith variable displacement capability.
• 125: Theoretical displacement (unit: cm³/rev), representing a per-revolution displacement of 125 mL, reflecting torque output capacity.
• 61W:
• 61: Control method code, denotinghydraulic servo control(external hydraulic signal-based displacement adjustment).
• W: Mounting form code, indicatingflange mounting + splined shaft connection, compatible with standard mechanical interfaces.
• VZL171:
• V: Seal type code, representingdual-lip seals + wiper ring, suitable for high-dust environments.
• Z: Axial clearance adjustment code, indicatingautomatic clearance compensationto reduce leakage over time.
• L171: Bosch Rexroth's internal batch or customization code, potentially involving special materials, coatings, or customer-specific requirements.
2. Structural Design & Operating Principle
• Bent-Axis Configuration:
• Pistons and driveshaft form a25°–30° inclination angle, converting hydraulic energy to mechanical energy via rotating cylinder blocks.
• Advantage: Higher axial load capacity compared to swashplate motors, ideal for heavy-duty applications.
• Variable Displacement Control:
• Displacement adjusted via aproportional valveregulating servo piston position, enabling stepless displacement control (0%–100%).
• Control accuracy: ±1% displacement error, response time <50 ms.
• Key Components:
• Piston/Cylinder Assembly: Precision-lapped with hard chrome plating (HRC 60–62) for wear resistance.
• Port Plate: Dual-metal sintered structure with >5,000-hour wear life.
• Bearing System: Tapered roller bearings for combined radial/axial load support.

4. Performance Features
• High Power Density:
• 125 cm³/rev displacement delivers 420 Nm torque, suitable for driving large winches and slewing mechanisms.
• Variable Flexibility:
• Hydraulic servo control supports remote displacement adjustment, ideal for excavator boom/arm coordination.
• Durability:
• Automatic clearance compensation (Z code) limits leakage increase to <5% over long-term operation.
• Environmental Adaptability:
• VZL seal combination passes IP67 testing, enabling submersible installation (e.g., underwater equipment).
5. Application Scenarios
• Construction Machinery:
• Drive systems for excavator travel/slewing, crane luffing mechanisms.
• Mining Equipment:
• Roadheader cutting head drives, conveyor tensioning systems.
• Industrial Vehicles:
• Forklift lift/tilt hydraulics, AGV steering drives.
• Marine Engineering:
• Deck machinery (anchor winches, mooring winches), deep-sea drill thrusters.
6. Selection & Compatibility
• System Matching Considerations:
• Ensure pump flow range covers motor’s max displacement × max speed.
• Use pressure-compensated valves to prevent overpressure.
• Alternative Options:
• Lower-displacement models (e.g., A2FE80) for light-duty applications to reduce costs.
• Competitor comparisons: Kawasaki K3V125, Linde HMR125 (evaluate efficiency curves and seal longevity).
7. Maintenance & Troubleshooting
• Routine Inspections:
• Oil cleanliness: Maintain NAS 7 or better (install return-line filters).
• Case drain port: Regularly drain condensation to prevent internal corrosion.
• Common Failures:
• Loss of Power: Check servo valve spool sticking or variable cylinder internal leakage.
• Abnormal Noise: Loose piston ball joints or worn port plates.
• Leakage: Aged seals or cracked housing (pressure-test to confirm).
• Maintenance Intervals:
• Replace hydraulic oil and filters every 2,000 hours.
• Disassemble for inspection every 5,000 hours (check piston-to-cylinder clearance ≤0.03 mm).
8. Industry Trends
• Electrification Integration:
• Development of electro-hydraulic hybrid drives with integrated electronic variable pumps, reducing energy consumption by >20%.
• Digitalization:
• Built-in sensors for pressure/temperature monitoring and CAN bus fault预警 (predictive maintenance).
• Material Innovation:
• Carbon fiber-reinforced polymer (CFRP) housings for 30% weight reduction and enhanced impact resistance.
