A2FE Series Fixed Piston Motor

Product Overview

A2FE Series Fixed Piston Motor is fixed displacement Hydraulic piston motor, serving as the power output component for closed-loop hydraulic system of heavy-duty mobile Machine. As a high-torque hydraulic motor, it converts hydraulic pressure energy from the hydraulic system into rotary mechanical torque to drive winch, slewing and crawler travel mechanisms of engineering Machine. Unlike variable motors, this Hydraulic piston motor features fixed swashplate angle with constant displacement, delivering stable torque output once the oil pressure of the hydraulic system is determined.

The A2FE series covers multiple displacement options. Original and domestic replacement versions are available. The mounting flange, oil port layout and output shaft dimensions keep consistent with original specifications, enabling direct replacement without modifying the existing hydraulic system.

Working Principle

When the Machine starts to work, high-pressure hydraulic oil from the hydraulic system enters the cylinder block of this Hydraulic piston motor. The pressurized oil pushes the pistons against the fixed-angle swashplate and generates continuous rotary motion of the output shaft. Since the swashplate angle cannot be adjusted, the displacement of this fixed hydraulic motor remains unchanged. The output torque varies according to the pressure of incoming hydraulic oil. The output speed changes with the oil flow supplied by the hydraulic system. Heavy-duty bearings and precision piston-valve pairs ensure stable rotation under continuous heavy load and vibration.

Core Advantages

1. A2FE Hydraulic piston motor provides large starting torque and stable rotation performance, ideal for constant-torque working demands of Machine.

2. Simple fixed-displacement structure, fewer internal control parts, low failure rate and easy maintenance for the hydraulic system.

3. Robust cast housing and high-quality sealing components, strong shock and vibration resistance, reliable performance under harsh construction site conditions.

4. Standard installation interface, interchangeable with original parts. No need to redesign the hydraulic system during replacement.

5. Cost-effective aftermarket spare parts, suitable for equipment overhaul and inventory stocking for global hydraulic spare part distributors.

Application Range

This series hydraulic motor is widely used in the hydraulic system of crawler cranes, winch devices, drilling rigs, crawler transport vehicles and other heavy-duty mobile Machine. It is commonly used for rotary drive and winch drive in closed hydrostatic transmission circuits, for new machine assembly and maintenance replacement.
