YLH servohydraulic load frames actuators are fatigue rated and cylinder tie rods are preloaded to beyond capacity of actuator.

For increased resistance to eccentric loads which may occur during testing, particularly at failure of structure at end of test, actuators have large rod diameter and long low friction polymer bearings.

Low friction seals for servo-hydraulic applications contribute to efficient operation due to minimal frictional pressure loss.

High precision servovalves installed enable precise operation over a wide range of test speeds, particularly at very low test speeds which are common in structural testing.

High precision fatigue rated load cell are mounted on piston rod via a high resolution alignment fixture. Base mounting may be provided on demand.

Integrated magnetostrictive displacement sensor provides precise feedback signal to the control system.
