Features
  • proportional speed control Output speed is directly proportional to input flow and inversely proportional to displacement, ensuring precise operation.
  • torque adaptability Drive torque increases as the pressure difference between the motor’s high-pressure and low-pressure sides grows, providing powerful performance.
  • compact and efficient design Features a high power-to-weight ratio and optimized volumetric efficiency, making it ideal for space-constrained systems.
  • integrated axial piston design Built with a one-piece tapered piston with a piston ring, enhancing durability and efficiency.
