Gas Springs Specification Technical Specification All gas springs packages are supplied with: ✦ 2 Gas springs including a release valve, ✦ 4 Metal eyes, ✦ 4 Metal ball joints with metric stud, ✦ 1 Gas release key (stud), ✦ 1 Instruction leaflet Operating Temperature range : from -5ºc to +70ºc Steel zinc or chrome plated metal end-fittings Steel chrome plated rod Steel black painted body Manufactured in the United Kingdom DO'S DON'TS ✦ Do use standard gas springs rod down. ✦ If springs are to be stored prior to use, it should be stored rod down to lubricate the rod seal. ✦ Do try to use ball joints to help avoid side load forces. If eyes are used, ensure a sloppy fit to allow lateral movement. ✦ Do ensure that the end-fittings are in line so that side load forces are not applied as a result of misalignement. ✦ Do try to use shorter springs close to the hinge rather than long stroke springs away from the hinge. ✦ Do provide physical stops to limit the spring's extremes. i.e. ensure that undue force is not applied to over compress or over extend the spring. ✦ Ensure the gas spring's end-fittings are fully screwed home. ✦ Where ball joints are used ensure the ball stud is flush with the surface and tightened. Size 6 mm rod - Charged at 400N with Release Valve 10 ✦ Do not scratch, dent, chip, bend or paint the rod. ✦ Do not puncture or incinerate. Please contact customer support for disposal instructions. ✦ Do not lubricate the gas spring. ✦ Do not cycle more than 15 times per minute. ✦ Under no circumstances attempt to regas a spring. This is an extremely hazardous operation. ✦ Do not reduce the force of the spring below its specified minimum working force Minimum working force: 40N Shoulder Length Stroke 10 Ø15 Ø6 M6 x 1.0 M6 x 1.0 22 Ø8 M6 19 10 M5 Package Shoulder Order Code Stroke Length 7100668 60 184 7100670 100 264 7100681 150 364 7100693 200 464 6 18 M6 Ø6 9 Ø10 Lengths in mm (+/- 2mm) Page 1 of 3 Gas Springs Specification Size 8 mm rod - Charged at 600N with Release Valve 13 Minimum working force: 100N Shoulder Length Stroke 13 Ø18 Ø8 M8 x 1.25 M8 x 1.25 30 Ø13 Package Shoulder Order Code Stroke Length 7100700 100 268 7100814 150 368 7100826 200 468 7100838 250 568 M8 29 17 M8 9 21 M8 Ø8 10 Ø14 Lengths in mm (+/- 2mm) Size 10 mm rod - Charged at 1200N with Release Valve 10 Minimum working force: 150N Shoulder Length Stroke 10 Ø23 Ø10 M10 x 1.5 M10 x 1.5 30 Ø13 Package Shoulder Order Code Stroke Length 7100840 100 265 7100851 200 465 7100863 250 565 7100875 300 665 M10 29 17 M8 10 30 M10 Ø8 14 Ø16 Lengths in mm (+/- 2mm) Size 14 mm rod - Charged at 2500N with Release Valve 14 Minimum working force: 250N Shoulder Length Stroke Ø14 14 Ø28 M10 x 1.5 M10 x 1.5 35 Ø16 M10 36 20 M10 Package Shoulder Order Code Stroke Length 7100887 100 280 7100889 200 480 7100905 300 680 7100917 400 880 7100929 500 1080 10 35 M10 Ø8 16 Ø20 Lengths in mm (+/- 2mm) Page 2 of 3 Gas Spring's Force Adjustement ADJUSTING A STANDARD COMPRESSION GAS SPRING WITH A RELEASE VALVE ✦ Upon receipt fit the gas spring to the application, operate the springs and observe the movement. Care should be taken on this first compression. The supplied force in the spring might be so great that damage could occur to the part to which the gas springs are attached. For example, if the springs are attached to a sheet metal lid. ✦ Safely support the load and remove the gas springs. Unscrew the end-fitting from the body end (the piston chamber). There may be a threaded stud located in the body that will also need to be removed, please note that this stud has a hole drilled on one end of it to fit over the valve. The valve can now be seen by looking down into the gas spring. ✦ Hold the spring with the rod down and the valve facing away from you. Screw in the release valve key until you can feel the tip of the valve. In one flowing movement turn clockwise a quarter of a turn and immediately turn anti-clockwise a quarter of a turn. The sound of escaping gas should be heard (it is best to carry out this procedure in a quiet environment). ✦ The gas spring has a very small volume of nitrogen at high pressure. On the small size 6 and 8 mm springs, a release of nitrogen lasting more than a second could reduce the spring's force by 100 Newtons. ✦ Refit the gas springs to the application. If the force is still too great, repeat the above procedure until satisfied. If two gas springs are attached remove approximately the same amount of gas from each spring. ✦ If, as it occasionally happens, you let out too much gas, it is possible to recharge release valved springs. Please contact Farnell InOne technical support. FOR A VARIETY OF REASONS IT IS EXTREMELY DANGEROUS TO ATTEMPT TO REGAS THE GAS SPRINGS. THIS SHOULD NOT BE ATTEMPTED UNDER ANY CIRCUMSTANCES.
