Hydraulic dampers

Hydraulic dampers from QHB series are maintenance-free, self-contained and sealed units. They are available with body diameters from 15 mm up to 40 mm (70 mm upon request) and with stroke lengths of up to 800 mm. As standard they are supplied as double acting dampers but a single acting version is also available. The single acting version is controllable in one direction only, with free flow in the opposite direction. The travel speed is adjustable and remains constant throughout the stroke.
The new adjustment segment on the piston makes sensitive speed adjustment easy. Hydraulic dampers sport the sleek design of our gas springs.
The body has a black powder coated finish and the piston rod has a special hard ceramic coating which provides an exceptionally long lifetime and excellent corrosion protection. A wide range of screw on mounting accessories makes them very versatile and easy to install.
Typical applications include machine guards and lids, fire safety flaps and doors, damping oscillations of sus-pended loads (Power and Free Systems) etc..
