Lengths, diameters, forces and colour correspond to ISO 10243. F1 indicates the load on the spring for a long service life with spring travel of 25% of L0. F2 indicates the load on the spring for a medium service life with spring travel of 30% of L0. Fmax. indicates the maximum load rating of the spring with spring travel of 40% of L0. F = force required to compress the spring 1 mm.

Individual filled gas springs are excluded from replacement. Gas springs are maintenance-free, self-contained systems that are filled with nitrogen under high pressure. For end-of-travel damping and lubrication, a defined amount of oil is also contained inside. The gas springs contain a nonreturn valve in a threaded pin on the pressurised pipe, which allows the pushing force to be lowered at a later time. Gas pressure springs in the sizes 04/12 and 06/15 must be stored and installed with the piston rod extending downwards. As of size 08/19, storage and installation in any orientation is possible. Keep in mind, however, that end-of-travel damping is effective only when the piston rod extends downwards. As a consequence of the physical properties when filling a gas spring, a tolerance range of ±5 % results for the rated pushing force. Gas springs are filled with nitrogen under high pressure and under no circumstances should they be opened or overloaded.

The combination of excellent material properties is a special feature of silicon nitride (Si3N4). These include high resiliance and stability, excellent wear properties and good chemical resistance.

The lateral spring plunger must be pressed into the hole to at least depth L3. These plungers are for positioning and holding small parts in fixtures. If mechanical machining of the workpiece is to be carried out, other clamps may be necessary. When the fixture is not in use it should be ensured that plastic springs are not under stress. Spring force refers to a mean value.
