Product Introduction
ATUS AA6VM series bent-axis variable displacement axial piston motor is engineered for hydrostatic transmission in both open and closed hydraulic circuits. Featuring tapered piston rotary assembly, it delivers wide adjustment range from max displacement down to zero displacement. High power density and stable high-pressure performance make it ideal direct replacement for mobile heavy machinery. Multiple displacement sizes and diverse control options are available.
