The Bosch Rexroth A6VE80HA3T/63W-VAL22200B (R902170428) is a state-of-the-art axial piston variable motor designed for high-efficiency applications requiring compact solutions. This motor features a space-saving construction thanks to its recessed mounting flange, which allows for seamless integration into mechanical gearboxes. Its easy installation process is facilitated by simply sliding the motor into place, minimizing downtime and simplifying maintenance procedures. With its wide control range, the A6VE80HA3T/63W-VAL22200B motor offers exceptional versatility and can be swiveled to zero, enabling precise control over a broad spectrum of operational conditions. It is also approved for very high speeds, making it suitable for applications that demand rapid response and quick adjustments. The high torque output of this motor ensures robust performance even under demanding load conditions. Additional customization options include an optional attached flushing and boost pressure valve, which enhances the motor's operational reliability and longevity by maintaining optimal fluid cleanliness and pressure levels. For applications requiring enhanced stability, there is an option to integrate or attach a counterbalance valve directly to the motor. The bent-axis design of this Bosch Rexroth variable motor contributes to its overall efficiency and durability. By optimizing the angle of the pistons in relation to the drive shaft, it achieves better mechanical leverage and smoother power transmission. This design feature also contributes to the compactness of the unit, further emphasizing its suitability for applications where space constraints are a critical factor. In summary, the Bosch Rexroth A6VE80HA3T/63W-VAL22200B (R902170428) combines a compact design with high-speed capabilities and customizable options to meet various application demands while ensuring reliable performance in a range of operational environments.
