Material:
Piston rod and pressure tube steel.
Fill medium: oil, nitrogen.
Version:
Piston rod, hard chromed.
Piston rod Ø4 is stainless steel.
Pressure tube painted black.
Note:
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.
