Rexroth A6VM160 Series Heavy-Duty Bent-Axis Variable Motors

Product Overview: The Rexroth A6VM107 Series is the power epicenter for global ultra-heavy-duty mobile machinery drives. Featuring a sophisticated bent-axis variable displacement design, this large-capacity motor is engineered to withstand extreme torque and high-pressure conditions. This featured selection includes: A6VM160HD2/63W-VZBO1700B (Hydraulic Proportional Control) and A6VM160HA1/63W-VZB380A-SK (Automatic High-Pressure Control with SK Specs). With its robust 160cc displacement, this series is the premier choice for large excavator travel drives, heavy crawler crane winches, TBM propulsion, large rotary drilling rigs, and mining machinery.

Key Technical Advantages:

• Precise Dual Control Strategies: HD2 offers fine hydraulic proportional regulation where displacement changes linearly with pilot pressure. HA1 provides intelligent automatic high-pressure regulation, adjusting displacement based on load pressure for an optimal balance of speed and torque.

• Extreme Torque Output: The 160cc/rev nominal displacement combined with 45° bent-axis technology ensures smooth and massive starting torque, managing heavy-load climbing with ease.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities up to 450 Bar, maintaining structural stability under extreme stress cycles.

• Rugged Series 63 Architecture: Equipped with reinforced bearing systems and high-strength VZB splined shafts, optimized for continuous heavy-duty operation to significantly extend service intervals.

• SK Specialized Compatibility: The VZB380A-SK configuration provides specific optimizations for industrial standards or specialized winch applications, enhancing system integration.

• Target Applications: Heavy crawler travel propulsion, large crane winch drives, forestry harvesters, and mining transport vehicle drives.
