Product Introduction
ATUS F12 series bent-axis fixed displacement axial piston unit can serve as both hydraulic motor and pump, engineered for heavy-duty open and closed hydraulic circuits. Adopting 40° bent-axis spherical piston structure with laminated piston rings, it delivers outstanding high-pressure & high-speed performance. Multiple displacement options from 30cc to 250cc are available, standard SAE/ISO mounting dimensions support direct drop-in replacement for mobile and industrial hydraulic systems.
