Description
The H1B variable displacement hydraulic motor is designed for high-performance closed-circuit hydraulic systems where efficient power transfer and precise control are essential. Featuring a robust bent-axis design with spherical pistons, this motor delivers reliable operation across a wide range of demanding applications.
With a displacement ratio of up to 5:1, the H1B motor offers exceptional flexibility, providing maximum displacements from 60 cm³ to 250 cm³. This allows the motor to adapt easily to varying load and speed requirements while maintaining consistent performance.
The H1B motor supports rated output speeds of up to 2,350 rpm at maximum displacement and 4,300 rpm at zero displacement, making it ideal for applications that require both high torque and high-speed capability.
Engineered for durability and efficiency, the H1B variable displacement motor is a dependable choice for advanced hydraulic systems used in industrial, mobile, and heavy-duty environments.
