Product Introduction
ATUS A6V series bent-axis variable displacement axial piston hydraulic motor is designed for hydrostatic transmission in both open and closed circuits. It features infinitely adjustable displacement from maximum to near zero, delivering flexible switch between high-speed low-torque and low-speed high-torque output. Multiple control options and displacement sizes are available, standard mounting dimensions support direct drop-in replacement for mobile and industrial hydraulic systems.
