FAQ (Frequently Asked Questions)

Q1: What is the main structural advantage of the A2FM bent-axis design compared to other piston motors?
A1: The bent-axis design typically offers higher volumetric and mechanical efficiency, especially at high continuous pressures. It generally has better high-speed and high-pressure performance characteristics, along with high resistance to shock loads, making it exceptionally durable for demanding loader applications.

Q2: How is the motor protected against contamination from the harsh environments where loaders operate?
A2: It employs a multi-layered sealing strategy. High-quality shaft seals prevent external contamination, while internal port plate design and optimized clearances minimize the negative impact of fluid contamination. Models designated for severe environments may feature enhanced sealing packages.

Q3: Can the A2FM motor be used in closed-circuit hydrostatic drive systems for wheel loaders?
A3: Yes, absolutely. The A2FM series is very commonly applied in closed-loop hydrostatic travel drives. Its high efficiency and wide speed range make it an excellent match for the variable speed and high-torque demands of loader propulsion systems.

Q4: We need a replacement motor for a conveyor drive, referenced as part number 87310111. Can you supply it?
A4: Yes. We specialize in supplying and cross-referencing hydraulic motors for specialized OEM equipment. For precise technical specifications and compatibility verification for components like 87310111 or 236393, please contact our engineering team via www.baolilai-pump.com/contact_us/.
