Rexroth A6VM160 Series Heavy-Duty Bent-Axis Variable Motors

Product Overview: The Rexroth A6VM160 Series is the power epicenter for global heavy-duty mobile machinery drives. Featuring a sophisticated bent-axis variable displacement design, this large-capacity motor is engineered to deliver maximum torque under extreme pressure. This selection includes: A6VM160HD2/63W-VZB020A (Hydraulic Proportional Control) and A6VM160HA2T/63W-VZBO20A (Automatic High-Pressure Control with Auxiliary Function). With its robust 160cc displacement, this series is the top choice for large excavator travel drives, heavy crane winches, TBM propulsion, rotary drilling rig power heads, and mining machinery.

Key Technical Advantages:

• Dual Precision Control Strategies: HD2 offers fine hydraulic proportional regulation; HA2T features automatic high-pressure regulation, adjusting displacement based on load pressure without external signals to balance speed and power.

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

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities up to 450 Bar, managing the most strenuous duty cycles with ease.

• Rugged Series 63W Architecture: Equipped with reinforced bearing systems and high-strength VZB020A / VZBO20A splined shafts, optimized for continuous heavy-duty operation to significantly extend service life.

• HA2T Enhanced Characteristics: The “T” designation signifies specific control auxiliary functions, providing superior sensitivity to pressure fluctuations and improved handling in complex operations.

• Target Applications: Heavy crawler travel propulsion, large crane winch drives, forestry harvesters, and Hydrostatic Transmissions.
