OEM Parts for Rexroth A4VSO Series | OEM aftermarket new

Housing: The pump's housing is made of high-quality materials such as cast iron or steel, ensuring durability and resistance to external forces.

The housing provides a robust structure that protects the internal components and maintains the pump's overall integrity.

Drive Shaft: The drive shaft transfers the rotational force from the motor or engine to the pump's internal components. It is precisely engineered to withstand high torque and speed, ensuring efficient power transmission.

Cylinder Block: The cylinder block houses the pistons and swashplate mechanism. It is designed with precision-machined bores to accommodate the pistons and control their reciprocating motion.

Pistons: The A4VSO series features pistons that are precisely machined to maintain tight tolerances and ensure smooth operation. These pistons are responsible for generating hydraulic pressure by reciprocating within the cylinder bores.

Swashplate: The swashplate is a critical component that converts the rotary motion of the drive shaft into reciprocating motion of the pistons. It is designed to precisely control the angle of the pistons, allowing for variable displacement and flow control.

Valve Plate: The valve plate contains various control valves that regulate the flow of hydraulic fluid to the cylinders. It ensures efficient and precise control of the pump's output by adjusting the position and timing of the valves.

Bearings: The A4VSO series incorporates high-quality bearings to support the rotating components, such as the drive shaft and swashplate. These bearings minimize friction and enable smooth operation, resulting in improved efficiency and reduced wear.

Seals: Seals are used throughout the pump to prevent leakage of hydraulic fluid and maintain system efficiency.

They are designed to withstand high pressures and provide reliable sealing under various operating conditions.

Control Mechanism: The A4VSO series offers different control mechanisms, including hydraulic servo and electric proportional control, allowing for precise adjustment of the pump's output based on application requirements. These control options provide flexibility and enhance the overall performance of the system.

Integrated Pressure Relief Valve: The pump is equipped with an integrated pressure relief valve to protect the hydraulic system from overpressure. This feature ensures the safety and reliability of the system by preventing damage to the pump and other components.
