Product Description
Rexroth A6VM250 Series High-Pressure Axial Piston Variable Motors
Product Overview: The Rexroth A6VM250 Series is a powerhouse of hydrostatic transmissions, specifically engineered to manage the most rigorous heavy-duty drive requirements. Featuring an axial piston bent-axis design, the A6VM250 is renowned for its exceptional power density and wide control range. This selection features core and specialized configurations: A6VM250HD1D/63W1-VZB150B-SO90, PZB020B, PZB010B, and VZB020B. Equipped with HD1D (Hydraulic Pilot Control), these motors provide precise displacement adjustment at peak pressures up to 450 Bar, making them ideal for large crawler drives, winch machinery, and rotary drilling heads.
Key Technical Advantages:
HD1D Precision Hydraulic Pilot Control: Utilizes pilot pressure for rapid response times, ensuring smooth and accurate speed transitions and torque distribution under complex load conditions.
Superior Speed Versatility: Seamless displacement adjustment from maximum to minimum (ratio up to 3.47) allows for high starting torque and efficient high-speed operation.
High-Pressure Robustness: Rated for 400 Bar (5800 PSI) continuous and 450 Bar (6500 PSI) peak pressure. Built with reinforced rotating groups and heavy-duty bearings for extended service life.
Specialized Customization (SO90): Features optimized sealing and port configurations for specific applications, ensuring maximum system compatibility.
Target Applications: Heavy-duty crawler travel drives, mining winches, rotary drilling power heads, large cranes, and industrial conveyor systems.
