Product details
A2FE Series Fixed Displacement Motor
The A2FE Series Fixed Displacement Motor, produced by Bosch Rexroth, is a high-performance axial-piston fixed displacement hydraulic motor widely used in various industrial and mobile equipment applications. Below is a detailed overview:
I. Technical Features
1. Axial-Piston Design:
• The A2FE series employs an axial-piston conical rotor group with a tilted-axis design, offering a compact structure and high efficiency.
• The tilted-axis design ensures stable operation under high pressure and delivers substantial output torque.
2. Fixed Displacement:
• With a constant displacement, the output speed depends on the pump's flow rate, while the output torque increases with the pressure differential between the high-pressure and low-pressure sides.
• Suitable for applications requiring constant rotational speed and torque.
3. High-Pressure Performance:
• Rated pressure up to 35 MPa (some models up to 40 MPa), with peak pressure reaching 400 MPa (some models up to 450 MPa).
• Capable of stable operation in high-pressure environments, meeting the demands of heavy-duty equipment.
4. Compact Structure:
• The mounting flange is designed in the middle of the housing, allowing the motor to be almost entirely integrated into mechanical gearboxes, providing a highly compact component.
• Easy to assemble, requiring only "insertion" into the mechanical gearbox without considering mounting tolerances.
5. Long-Life Bearings:
• Utilizes a robust rolling bearing system to ensure long service life and high reliability.
• Suitable for high-load and continuous operation applications.
6. Multiple Displacement Options:
• Available in various displacement models, including 28, 32, 45, 56, 63, 80, 90, 107, 125, 160, 180, 250, and 355 cm³, to meet different application requirements.
II. Application Areas
The A2FE series fixed displacement motors are widely used in the following fields:
1. Construction Machinery:
• Such as the slewing and traveling systems of excavators, loaders, and cranes.
2. Industrial Equipment:
• Including hydraulic systems for metallurgical machinery, plastic machinery, and forging presses.
3. Marine Machinery:
• Such as anchor winches, capstans, and cargo winches on ships.
4. Mobile Equipment:
• Including hydraulic transmission systems for crawler drive gearboxes and agricultural machinery.
