Rexroth A6V500 Series Large Displacement Variable Motors

Product Overview:

The Rexroth A6V500 Series is a heavy-duty variable displacement axial piston motor featuring a proven bent-axis design. As a powerhouse in the A6V family, the A6V500 is renowned for its exceptional power density and wide control range. This selection features core high-performance configurations: A6V500 HD6.2FZ (including specific part codes 23450-866-0 and 23450-875-0). Equipped with HD6.2 (Hydraulic Direct Control), these motors provide precise displacement adjustment at peak pressures up to 400 Bar, making them the definitive choice for marine winches, mining machinery, and heavy industrial presses.

Key Technical Advantages:

• Extreme Displacement & Torque: With a nominal displacement of 500 cm³/rev, it delivers massive starting torque even at low speeds, ideal for heavy-load operations.

• HD6.2 Precision Hydraulic Control: Features a reliable hydraulic regulation mechanism for smooth response, enabling stepless displacement from $V_{max}$ to $V_{min}$ based on pilot pressure.

• High-Pressure Robustness: Rated for 350 Bar (5100 PSI) continuous and 400 Bar (5800 PSI) peak pressure. Built with reinforced rotating groups and heavy-duty bearings for extended service life in harsh environments.

• Bent-Axis Efficiency: Compared to swashplate designs, bent-axis technology offers a wider control range (ratio up to 3.47) and higher mechanical efficiency, significantly reducing system heat.

• Target Applications: Marine anchor windlasses and winches, large crawler drives, mining crushers, Tunnel Boring Machines (TBM), and heavy forging equipment.
