Product Description

The A4FM series hydraulic motors, produced by the manufacture, are high - pressure, fixed - displacement axial piston motors. They are designed for use in both open and closed - loop circuits for hydrostatic drives. These motors are particularly suitable for applications where a compact installation size is required.
 
The output speed of the A4FM motor is proportional to the input flow and inversely proportional to the motor displacement. The output torque increases with the pressure drop across the motor between the high - and low - pressure sides. The A4FM motor is available in displacement sizes of 22, 28, 40, 56, 71, 125, 250, and 500 cc / rev. The nominal pressure is 350 bar, and the maximum pressure is 400 bar.
 
Some notable features of the A4FM series hydraulic motors include high tolerance to torsional vibrations, long service life at high pressures, very high total efficiency, low operating noise, and a swashplate design. These characteristics make the A4FM series motors widely used in various industrial fields, such as mobile and construction equipment, engineering vehicles, metal forming and stamping, machine tools, hydraulic presses, oilfield equipment, mining and metallurgical machinery, and marine hydraulic systems.

The A4FM series hydraulic motors have a wide range of applications in various fields:
 
Mobile and Construction Equipment
- In excavators, they power the rotation of the boom, bucket, and swing mechanism, enabling precise and efficient movement.
- For loaders, they provide the necessary torque to drive the wheels and operate the lifting and dumping mechanisms.
 
Engineering Vehicles
- In concrete pump trucks, they are used in the hydraulic system to drive the pump mechanism, ensuring a continuous and stable supply of concrete.
- In cranes, they play a crucial role in the hoisting and slewing operations, providing high - power output.
 
Metal Forming and Stamping
- In presses, they supply the force required for metal stamping and forming processes, enabling high - precision shaping of metal sheets.
- In forging machines, they drive the hydraulic cylinders that perform the forging operations, facilitating the production of high - quality metal parts.
 
Machine Tools
- They are used in the hydraulic systems of machine tools to control the movement of the worktable and tool holders, ensuring accurate machining.
- In grinding machines, they provide the power for the rotation of the grinding wheels and the movement of the workpiece.
