Product Description
Rexroth A6VM355 Series High-Pressure Axial Piston Variable Motors
Product Overview: The Rexroth A6VM355 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 A6VM355 is renowned for its exceptional power density and wide control range. This selection features core and specialized configurations: A6VM355HD2/63W1-VZH010-VB-SO264, AL-A6VM355HD2/63W1-PZH020VB, VZH020B-SO27, VZH010B, and VZH010VB. Equipped with HD2 (Hydraulic Direct Control), these motors provide precise displacement adjustment at peak pressures up to 450 Bar, making them ideal for large crawler drives and heavy winch systems.
Key Technical Advantages:
HD2 Precision Hydraulic Control: Utilizes pilot pressure proportional adjustment for rapid response times, ensuring smooth and accurate speed transitions under complex load conditions.
Superior Speed Versatility: Seamless displacement adjustment from maximum to minimum 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 (SO264/SO27): Features specialized configuration codes for specific industry applications like Tunnel Boring Machines (TBM) or large cranes, ensuring maximum compatibility.
Target Applications: Crawler travel drives, mining winches, rotary drilling power heads, heavy industrial mixers, and large-scale conveyor systems.
