A2FM Rexroth Axial Hydraulic Motor High Power for Mining Equipment

A2FM REXROTH AXIAL HYDRAULIC MOTOR High Power for Mining Equipment

1, Product Overview
The A2FM series is a Rexroth axial piston motor known for its durability, high efficiency, and high power density. This series of motors is the core power component of closed-loop hydraulic systems, widely used in various demanding industrial, engineering, and marine fields.
2, Core features and advantages
1. Excellent power density:
·Adopting a compact inclined axis design, it achieves extremely high torque and power output within a limited installation space.
2. Extremely high efficiency and low-speed stability:
·The optimized plunger and port plate design ensures high volumetric and mechanical efficiency throughout the entire pressure and operating speed range.
·Excellent low-speed stability, capable of smooth start-up and non crawling operation at extremely low speeds, especially suitable for directly driving large wheels or rollers.
3. Durable and long-lasting:
·The heavy-duty roller bearing design can withstand extremely high radial and axial loads and has a long service life.
·The sturdy shell structure and high-quality component materials ensure the high reliability and long lifespan of the motor under harsh working conditions.
4. Wide applicability:
·The displacement range covers from 5.8 cm ³/rev to 500 cm ³/rev, providing multiple specifications to meet different torque and speed requirements.
·The working pressure is high, with a maximum continuous working pressure of 400 bar and a peak pressure of 450 bar.
5. Flexible configuration options:
·There are various forms of output terminals: providing spline shafts and flat key shafts for easy connection with various devices.
·Installation flange standards: comply with various international standards such as SAE, DIN, ISO, etc., with strong interchangeability.
·Optional integrated functions: such as flushing valve, parking brake, speed sensor, etc., to meet diverse system integration requirements.
6. Low noise operation:
·Precise machining and optimized flow pulsation characteristics ensure smooth motor operation with low noise levels.
