Adjustable gas spring - Gas spring - Works in compression (push mode) - Integrated valve - Progressivity: GSA15: about 27% GSA19: about 40% GSA22: about 45% - Speed and damping: GSA15: Normal speed, medium damping over 10mm approximately GSA19: Slow speed, strong damping over 20mm to 60mm approximately depending on the stroke. GSA22: Slow speed, strong damping over 20mm to 70mm approximately depending on the stroke - Operating temperature: -30°C to + 80°C - Materials: Steel rod ceramic coated (corrosion resistance 216h according to DIN50021SS) Steel body black epoxy paint Important: Spring must be mounted with piston pointing down. Adjustment - The gas spring are inflated to the force indicated - Let gas escape through the decompression valve using the adjustment screw to obtain the desired force. CAUTION: Once the gas has been released, spring cannot be refilled Use - Facilitate opening and closing of a bonnet or boot - Additional effort Adjustment screw : see pdf
