Helical Hydraulic Rotary Actuator - L30 Series
Brand: HelacParker Helac L30 Series Helical Hydraulic Actuator is a heavy duty rotary actuator that is suitable for harsh environments. Designed for applications that require high bearing capacity, the L30 Series features foot or flange output with 180-degree or 360-degree rotation. Helac’s helical, sliding spline technology is non self-locking while providing 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 high torque output up to 380,000 in-lbs at 3,000 psi.
Features- Powerful: High torque, high bearing capacity
- Durable: Moving parts enclosed, suitable for harsh environments
- Compact: High power density, fits in tight spaces
- Holds Position: Zero internal leakage, smooth operation, no external brake required
- Simplifies: Eliminates bearings, linkages & brackets, reduces bill of materials, simplifies supply chain, assembly and maintenance
- Backdrives in Overload Conditions: Hydraulic fuse, prevents mechanical damage when properly equipped
