MA32 Hydro Leduc Bent Axis Hydraulic Motor 32cc 400bar

Product Overview

The Hydro Leduc MA32 is a French-origin Hydro Leduc MA series bent-axis (40°) fixed-displacement axial piston hydraulic motor designed for open and closed circuits. Featuring a precision bent-axis piston design, it delivers global efficiency exceeding 90%, compact size, and optimized weight for high-speed and heavy-duty applications. Our MA32 (example code M005AD1P0G200SVF) and companion models MA50, MA63, MA80 are manufactured to original technical specifications, offering 100% interchangeability (flange, shaft end, and port positions fully match OEM) and 100% simulated-duty testing. They provide reliable, high-efficiency performance under continuous high pressure and speed, serving as cost-effective direct replacements for genuine Hydro Leduc motors.

Key Technical Advantages

1. Precision 40° bent-axis piston design and high-accuracy machining deliver global efficiency over 90%, low starting pressure, high power density, and optimized size/weight.
2. Reinforced shaft seals and robust bearings support continuous heavy-duty and high-speed operation (up to 6300–6900 rpm), with low noise and excellent durability.
3. Capability for series/parallel combination and flexible mounting (SAE/ISO flanges), ideal for intensive fixed and mobile applications.
4. Full dimensional and performance interchangeability plus rigorous simulated-duty testing guarantee drop-in replacement of original Hydro Leduc units, minimizing downtime and lifecycle costs.

Application Areas

Suitable for vehicle transmissions, high-power crushers, forestry equipment, heavy-duty winches, marine drives, construction machinery travel/auxiliary drives, and industrial hydraulic systems requiring high speed, high efficiency, and compact design. Typical uses include forestry machines, crushers, heavy winches, mobile vehicle drives, and intensive open/closed-circuit systems.

Expert Maintenance Tips

• Verify exact match of mounting flange (SAE J744), shaft end (14T splined J498b), and port orientation (rear configuration) before installation; avoid forced assembly that can damage seals or bearings.
• Maintain hydraulic fluid cleanliness to NAS 1638 Class 9 or better (ISO 18/15); recommended viscosity 15–200 cSt; regularly check case drain pressure (continuous ≤4 bar).
• Monitor temperature and speed during commissioning and service; enable flushing valve when required to prevent overheating or cavitation; minimum continuous speed approximately 200 rpm (down to 50 rpm under specific conditions).
• Use matching filter elements and mineral-based hydraulic fluid; record operating pressure and flow profiles to detect early efficiency decline.
