Rotary Actuators

The L10 Series is Helac's smallest and most compact helical hydraulic actuator. Ideal for applications where space is of premium importance, the ultra-compact L10 series features extremely high thrust capacity in a sleek cylindrical design with flanged mounting and flanged output. Helac's helical hydraulic sliding spline technology is not self-locking and provides high stock resistance and high holding torque for demanding applications. Functioning as a rotating device, mounting bracket and load bearing structure, the L10 Series eliminates the need for external bearing systems, brakes or locking devices. Five standard sizes with torque outputs up to 25,000 in/lbs at 3000 psi (2825 Nm at 210 bar) are variable. NB: Custom rotation limits available on request

The L20 Series is a cost effective solution that can easily be designed into a wide range of applications. It features versatile mounting options and flange output. Helac's Helical sliding spline technology is not self-locking and provides high shock resistance and high holding torque for demanding applications. Functioning as a rotating device, mounting bracket and load bearing structure, the L20 Series eliminates the need for external bearing systems, brakes or locking devices. Five standard sizes with torque outputs up to 39,000 in/lbs at 3000 psi (4400 Nm at 210 bar) are available. NB: Custom rotation limits available on request

The L30 Series is our heavy duty helical hydraulic actuator that is suitable for harsh environments. Designed for applications that require ultra high bearing capacity, the L30 Series features foot or flange mount with flange output. Helac's helical sliding spline technology is not self-locking and provides high shock resistance and high holding torque for demanding applications. Functioning as a rotating device, mounting bracket and load bearing structure, the L30 Series eliminates the need for external bearing systems, brakes or locking devices. Nine standard sizes with torque outputs up to 380,000 in/lbs at 3000 psi (43,000 Nm at 210 bar) are available. NB: Custom rotation limits available on request
