High Force Output
Generates significant force for lifting, pushing or pulling: up to 402 kN closing thrust at 160 bar on the 200 mm bore.
Precision Control
Accurate, smooth control of linear motion for applications that need fine adjustment, with speed control.
Electro-Hydraulic Option
EHLDA versions combine electric control with hydraulic power, with a power pack, accumulator or hand pump.
Low-Friction Cylinder
Honed, hot chrome plated cylinders and a dynamic sailing piston seal cut friction and prevent chattering, even after long idle periods.
High-Strength Stem
A high yield strength actuator stem carries large thrust loads, with a strong strength-to-weight ratio.
Onshore & Offshore
Custom engineered for onshore and offshore installations, with a manual override for power failure.
