Product Introduction
ATUS A2FM series bent-axis fixed displacement axial piston hydraulic motor is engineered for hydrostatic transmission in open and closed hydraulic circuits. Adopting one-piece tapered piston structure with piston rings, it delivers stable constant torque output proportional to system pressure difference. Displacement covers 10cc to 355cc, standard ISO mounting interfaces support direct drop-in replacement for mobile and industrial hydraulic equipment.
