Description

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.
On request
Other extension forces.

Gas springs

Gas springs from norelem are often used on opening systems and holding mechanisms in machine construction where they serve as support devices. In tool making, gas springs often take the place of conventional steel springs because of their high power density. When installing or removing gas springs it must always be ensured that they are not under load, as otherwise considerable damage could occur. The cylinder is filled with nitrogen and is under very high pressure. The check valve in the threaded pin of the pressure tube can be used to reduce the extension force.

At norelem there are over 300 varieties of gas springs.

norelem fills gas springs according to the customers individual specifications.
