Product Description
Parker M5BF & M5AF Axial Piston Fan Drive Hydraulic Motors
Product Overview: The Parker Denison M5B and M5A Series are high-performance axial piston fixed displacement motors specifically engineered for cooling fan drive systems. Renowned for their exceptional speed capabilities and power density, these motors are the premier choice for large excavator cooling fans, such as the Hitachi ZX470. This category highlights the precision-engineered models: M5BF-045-1N03-B1M-00000-52 (45cc) and M5AF-018-2R04-B1W-00000 (18cc). Built to withstand frequent starts, stops, and rapid reversals, the M5 series ensures maximum efficiency for engine cooling systems in the harshest environments.
Key Technical Advantages:
Optimized for Fan Drives: High mechanical and volumetric efficiency allows for precise fan speed regulation based on system demand, reducing fuel consumption and noise.
High-Speed & High-Pressure Resilience: Features reinforced piston groups and valve plates designed for sustained high-RPM operation with rated pressures up to 300 Bar.
Compact & Rugged Design: Lightweight yet durable housing options optimize installation within the restricted engine compartments of mobile machinery.
Extended Service Life: Equipped with high-performance bearings and low-friction seals, significantly increasing reliability in high-temperature operating conditions.
Target Applications: Hitachi ZX470/ZX450 cooling fans, heavy-duty truck hydraulic fan systems, and industrial power unit cooling arrays.
