Rexroth A6VM107 Series High-Pressure Bent-Axis Variable Motors

Product Overview: The Rexroth A6VM107 Series is the premier power source for heavy-duty mobile machinery drives worldwide. Featuring a legendary bent-axis variable displacement design, this motor is engineered for both open and closed circuits, providing constant power output across an exceptionally wide speed range. This featured selection includes: A6VM107HA1T/63W-VZB027A (Enhanced Control) and A6VM107HA1/63R-VSD51XA-S (Standard High-Pressure Control). With the specialized HA1 automatic control, these motors optimize displacement based on load pressure without external signals, making them the top choice for excavator travel drives, rotary drilling rigs, pavers, and heavy-duty winch systems.

Key Technical Advantages:

• Intelligent HA1 Automatic Control: Features pressure-related stepless displacement adjustment, ensuring maximum torque during high loads and high speed during low-load cycles.

• Multi-Interface Compatibility: Available with VZB (Splined Shaft) and VSD (Special Standard) interfaces to fit global machinery installation standards.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities up to 450 Bar, maintaining mechanical integrity under extreme overloads.

• Bent-Axis Efficiency: The classic 45° bent-axis architecture delivers maximum mechanical efficiency and starting torque, ensuring smooth, powerful operation even during heavy-load climbing.

• Rugged Series 63 Architecture: Reinforced bearing systems and specialized seals offer exceptional resistance to vibration and extended service life, significantly extending maintenance intervals.

• Target Applications: Crawler travel propulsion, heavy-duty crane winches, TBM (Tunnel Boring Machine) drives, forestry equipment, and hydrostatic transmissions.
