Technical Features

  • ASHUN's innovative 'Hydraulic Rotary Actuators' adopt a double-helix meshing drive design that transforms the piston's linear motion into rotary motion.
  • The design features an inner helical gear on the tube that engages with the outer helical gear on the piston, and an outer helical gear on the integrated central shaft that engages with the inner helical gear on the piston. This configuration ensures high dimensional precision, exceptional stability, and outstanding load capacity.
  • The driving torque and holding torque are almost linear with the hydraulic pressure.
  • As load increases, drive torque may decrease by as much as 15%.
