Rexroth A6VM160 Series High-Pressure Axial Piston Variable Motors

Product Overview:

The Rexroth A6VM160 Series motor is a high-performance benchmark in modern hydrostatic transmission systems. Featuring a bent-axis design, the A6VM160 is renowned for its superior power-to-weight ratio and wide control range (with a displacement ratio of up to $V_{max}/V_{min} = 3.47$). This selection covers core configurations: A6VM160-HD1D/63W-VAB020B (Hydraulic direct control), A6VM160-HA2/63W-VAB020A-S (Automatic high-pressure control), and A6VM160MA/63W-VZB020B (Manual/Mechanical control). Whether in excavator travel drives, large winch systems, or industrial mixing equipment, these motors deliver consistent torque and precise speed regulation at peak pressures up to 450 Bar.

Key Technical Advantages:

• Superior Speed Flexibility: Stepless displacement adjustment perfectly matches high startup torque requirements and high-speed operational demands.

• Versatile Control Synergy:

  • HD (Hydraulic Direct): Offers ultra-fast response times and precise positioning for highly automated systems.

  • HA (High Pressure): Automatically adjusts displacement based on load pressure to optimize energy consumption and prevent overload.

  • MA (Manual Control): Robust and reliable, ideal for manual intervention and specific field tuning.

• High-Pressure Robustness: Rated for 400 Bar (5800 PSI) continuous and 450 Bar (6500 PSI) peak pressure. Built with reinforced piston groups and heavy-duty bearings for extended service life in harsh environments.

• Excellent Starting Characteristics: Specialized valve plate designs ensure high mechanical efficiency, providing smooth startup and creep-free operation even at low rotational speeds.
