Clarification on the composition of our references :

The references on our site are those of our empty cylinders (without the force, we fill each gas spring on demand), the references of the finished products (filled) are composed as follows: ST 1000500D8 3223 (example of reference).
- The first 3 digits are the stroke, 
- The next 4 digits represent the force. If there is a V, it means that the gas spring is threaded (without end fittings). Otherwise it is a welded eyes gas spring.
- D represents the diameter of the rod. 
- The last 4 digits represent the filling date (week/year).

For our example the gas spring has a stroke of 100mm, a force of 500N with welded eyes, with a rod of diam 8mm and filled in week 32 of the year 2023.
* For the traction spring and dampers, the force is at the end of the reference.

On our website you will find them like this: ST 100+F1+D8.
The explanation is the same, F1 means the value of the force and should be replaced by the desired force (expressed in Newton).

We have chosen this system because we fill the gas springs on demand.

You can now search for the references on the grey labels on our gas springs via the search engine. During your research thank you not to enter the last 4 figures from date. (Example : 1000500D8 4116, becomes 1000500D8).

Force / Pressure of the gas spring

The force is very important in the gas spring, it is what will determine the good functioning (or not) of your application. You will find it in most cases with the reference on the body of the gas spring, it will be composed of 3 or 4 digits followed by a N (example: 0400N). If it is not the case it will be then necessary to calculate it. It is imperative to know the force to order on our site because we fill the gas springs on demand. For information 10N represents approximately a thrust of 1 kilo, attention the weight of the application alone is not enough to determine a force !

It will be necessary to pay attention at the time of the choice of the force to the diameter of the rod, that it is adapted to the possible range of force (mini and maxi).
