5 we carry the load. Operatg Technology Helac s novative, slidg-sple operation technology converts lear piston motion to powerful shaft rotation. Each actuator is comprised of a housg and two movg parts the central shaft and piston. Helical sple teeth on the shaft engage matchg teeth on the piston s side diameter. A second set of helical sples on the piston s outside diameter mesh with the gear the housg. STARTING POSITION The piston is completely bottomed out. Bars dicate startg positions of piston and shaft. The housg with tegral gear remas stationary. ENDING POSITION When hydraulic pressure is applied to the piston, it moves axially; while the helical gearg causes the piston and shaft to rotate simultaneously. Applyg pressure to the opposite port will return the piston and shaft to their origal startg positions.
