Rexroth A6VM107 Series High-Pressure Bent-Axis Variable Motors

Product Overview: The Rexroth A6VM107 Series is the industry performance benchmark for heavy-duty mobile machinery drive systems. Featuring a bent-axis piston design, this variable displacement motor is engineered for both open and closed circuits, providing constant power output across an exceptionally wide speed range. This selection includes two primary control configurations: A6VM107HD1/63W-VAB020B (Hydraulic Proportional Control) and A6VM107HA2/63W-VAB080 (Automatic High-Pressure Control). Renowned for its superior starting torque and shock resistance, the A6VM107 is the premier choice for excavator travel drives, rotary drilling rig power heads, crane winches, pavers, and hydrostatic transmissions.

Key Technical Advantages:

• Versatile Control Strategies: HD1 offers precise hydraulic proportional control, while HA2 automatically adjusts displacement based on system pressure to optimize power distribution.

• Bent-Axis Efficiency: The unique bent-axis architecture delivers maximum mechanical efficiency, ensuring smooth and massive torque output even at ultra-low speeds under heavy load.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, managing extreme stress cycles with ease.

• Ultra-Wide Speed Ratio: Supports an expansive range from maximum to minimum displacement, catering to both high-speed travel and low-speed precision work.

• Rugged Series 63 Architecture: Features reinforced bearings and specialized sealing systems with excellent vibration resistance, significantly extending service life in harsh environments.

• Target Applications: Crawler travel propulsion, heavy-duty winch systems, construction rotary drives, and TBM propulsion units.
