Helical Hydraulic Rotary Actuators

Parker Helac is a specialist in compact, high-torque helical hydraulic rotary actuators engineered for applications requiring powerful, controlled rotary motion within a compact installation envelope.

Using innovative sliding-spline technology, Helac actuators convert linear piston movement into controlled shaft rotation, combining high torque, exceptional load-bearing capability and rugged durability within a single actuator.

Unlike conventional rotary systems that may require separate cylinders, linkages, bearings and mounting structures, a Helac actuator can function simultaneously as a rotating device, mounting bracket and load-bearing structure.

At MONILEK Oilfield, Parker Helac complements our extensive capabilities in Hydraulics, Actuation, Fluid Power and Engineered Systems, allowing us to support customers with compact rotary-motion solutions for demanding mobile and industrial applications.
