Helical Hydraulic Rotary Actuator - T Series
Brand: HelacIdeal for applications where high torque generation and higher cycle rates are the primary requirements, the Parker Helac T Series Hydraulic Rotary Actuator features splined output shafts and 200-220 degrees of rotation. Helac’s helical, hydraulic 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 T Series eliminates the need for external bearing systems, brakes or locking devices. 4 standard sizes with torque output up to 60,000 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
