LT-A2FEW6.1 Series (45-180ml/r)

The LT-A2FEW6.1 series built-in constant displacement hydraulic motors are suitable for both open-circuit and closed-circuit hydraulic transmission systems. Featuring a fixed-displacement bent-axis design, output speed is proportional to input flow, while output torque increases with system pressure differential. With a built-in configuration, this pump/motor is well suited for direct integration into travel drives, slewing drives, and other compact drive units, meeting hydraulic application requirements for high integration density and compact structure.
