A2FM series bent-axis fixed-displacement axial piston hydraulic motorsfor A2FM80 excavator travel drives and crane winches.

1. Product Description

The A2FM80 is a high-pressure, fixed-displacement axial piston hydraulic motor featuring a classic 40° bent-axis design. With a standard displacement of 80 cm³/rev (80cc) and a peak pressure capacity of up to 450 bar, it is engineered for both open and closed-circuit hydrostatic drive systems, making it ideal for heavy-duty construction machinery and industrial drive equipment.

2. Key Advantages

• High Power Density and Efficiency: The compact bent-axis design minimizes the installation footprint while delivering exceptional volumetric and overall efficiency.
• Superior Starting Performance: Pistons act directly on the drive shaft to generate torque, ensuring high starting efficiency and smooth, steady operation at low speeds without "stick-slip" (jerking) motion.
• High-Pressure Durability and Long Service Life: Rated for operating pressures up to 400 bar, the unit incorporates high-strength rolling bearings and wear-resistant valve plates, enabling it to withstand continuous heavy-duty loads and shocks in demanding operating environments.
• Excellent Installation Compatibility: Designed in strict accordance with ISO standards for mounting flanges and shaft extensions, the motor supports bidirectional rotation and serves as a direct, drop-in replacement for equivalent imported units.
