Product Description
Rexroth A-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 speed range and power-to-weight ratio. This selection covers core and specialized configurations: A-A6VM355HA2/63W2-VZH020A, PZH010A, VZH017A, and the custom variants VZH027A-S0164 and VZH027FA-SO164. Equipped with HA2 (Automatic High-Pressure Control), these motors automatically adjust displacement based on system pressure, providing a perfect balance between efficiency and power at peak pressures up to 450 Bar.
Key Technical Advantages:
HA2 Intelligent Control: Automatically adjusts displacement to maintain a constant pressure/power ratio, significantly reducing heat generation and optimizing energy efficiency.
Superior Speed Versatility: Seamless displacement adjustment from maximum to minimum allows for high starting torque and high-speed operation, suitable for complex industrial tasks.
High-Pressure Robustness: Rated for 400 Bar (5800 PSI) continuous and 450 Bar (6500 PSI) peak pressure. Built with reinforced bearings and precision-engineered pistons for long service life.
Specialized Customization (S0164/FA): Features specialized configuration codes for specific industry applications like large crane winches or TBM cutter heads, ensuring maximum compatibility.
Target Applications: Heavy-duty crawler drives, mining winches, rotary drilling power heads, Tunnel Boring Machines (TBM), and heavy industrial conveyor systems.
