QS-12, QS-15, QS-19, QS-22, QS-28, QS-40 compression gas springs can be used in all applications in which lifting and lowering of masses must be controlled. They support manual forces and are used to control the opening and closing of covers, flaps, lids, etc. They are maintenance-free, self-contained and available from stock. Their integrated grease chamber provides lower release force, reduced friction and longer service life.
QS-12, QS-15, QS-19, QS-22, QS-28, QS-40 models are equipped with valves to obtain the desired force for all applications. The piston rod and tube are made of steel for standard models or aluminium on request. The piston rod is treated by an environmentally friendly steel surface ceramicization process called CeramPro®. The tube is treated with electrostatic powder coating, which has a longer service life and is more resistant to shocks and scratches than liquid paint. The fasteners and joints are made of steel or lead-free aluminium.
