Hydraulic Piston Motors

Product Information

The A2FM32-61WVBB is a fixed-displacement axial piston motor, featuring a bent-axis tapered piston design with a fixed displacement of 32cm³, suitable for open/closed hydrostatic circuits. Compact, high starting torque, low noise, durable and shock/vibration resistant, it’s widely used in construction machinery, forestry/agricultural equipment and industrial drives. It directly drives actuators, simplifies layout with excellent reliability and adaptability.

Product Summary

Known for their superior power density and durability, hydraulic piston motors excel in applications requiring high torque and precise speed control. The advanced piston design minimizes internal friction, resulting in efficient energy use and reduced heat generation. These motors maintain reliable operation even under fluctuating loads and extreme conditions, making them suitable for mobile machinery, mining equipment, and offshore systems. With excellent resistance to wear and high efficiency, hydraulic piston motors deliver long‑lasting performance and lower overall operating costs.

Product Operating Instruction

During installation, ensure precise alignment between the motor shaft and the driven shaft, using a flexible coupling to compensate for possible misalignment. It is imperative to use hydraulic oil with the recommended viscosity and cleanliness level (typically NAS 1638 Class 8-9) and maintain sufficient pressure at the inlet port (approx. 0.8-1.2 bar) to prevent cavitation. Before initial start-up, thoroughly prime and vent the motor through its case drain port. The motor is bi-directional; change the direction of oil flow to reverse rotation. After prolonged shutdown or oil change, run the motor under low load for a period to allow for proper running-in.

Product Application

This piston motor is widely used in various industrial equipment and mobile machinery that require compact size and continuous, stable operation. Typical applications include: screw drives for plastic injection molding machines, winding mechanisms for textile machinery, travel or swing drives for construction machinery, working device drives for agricultural and forestry machinery (e.g., headers for harvesters), and auxiliary equipment in the steel industry. Its outstanding reliability and broad adaptability make it an ideal choice for converting hydraulic power into steady mechanical rotary motion in hydraulic systems.
