Product concerned : Servo hydraulics
HiFi actuators : Servo hydraulics - Quiri
HiFi actuators are high efficiency linear actuators especially adapted to close loop control. Equipped with different kind of bearings,these actuators are dedicated to mechanical and dynamic tests : fatigue, characterization, durability….

HiFi actuators are fully modular and can be equipped as a standard with all necessary accessories: Sensors, accumulators, security and propection manifold blocks, mechanical accessories. Al the HiFi actuators are equipped with internal displacement sensors, LVDT or magnetostrictive technology.

HiFi PST actuators: Single ended rod polymer bearings
Force: 5kN to 10MN
Stroke: 20 to 1000 mm
Frequency: up to 5Hz ( depending on size)
Economic and compact in the small sizes, these actuators are available up to large sizes for low frequency structural or components tests.

HiFi P actuators: Double ended rod with polymer bearings
Force: 5kN to 3MN
Stroke: 20 to 500 mm
Frequency: up to 20Hz ( depending on application)
The HiFi P actuators, are the most use one in our HiFi range, for all components fatigue or characterization tests.

HiFi S actuators: Double ended rod with hydrostatic bearings
Force: 10kN to 1000MN
Stroke: 20 to 500 mm
Frequency: up to 150Hz
Equipped with hydrostatic bearings, these actuators can reach high frequencies and sustain important side load compare to classic designed actuators.

Accessories :
– Load cells
– servo- valves
– accumulators
– Hydraulic function manifold blocks
– Mechanical fixture accessories: Rod eyes barings, trunnions, swivel bases…
