All Gas Spring contain a small amount of oil to lubricate the main seal and rod. This oil also provides end-of-travel damping. If the standard gas spring is operated and installed in a rod-up manner, the fluid can not reach the primary seal or rod, which results in over-worn seals and shortened lifetimes. It is recommended that a standard gas spring be mounted on a pole that is at least 30 degrees in the horizontal. If the application does not adapt to the installation, you should specify an oil or oil chamber. Both are optional features.

Why should I use the spring bar? To keep the rod seal lubricated, use a small amount of oil for each gas spring. When using the tie rod, the oil remains in contact with the rod seal, which improves the sealing performance and ensures that the seal never dries.

For this reason, one of the basic suggestions for adding a gas spring to your design is to make sure that they are used less than 60 degrees.

The oil used in gas springs is also useful for achieving high damping on the last few millimeters of travel. Without the use of a gas spring, the piston does not have to pass through the oil at the end of the extension and damping effects do not occur.

When this is not possible and the gas spring must be rod-shaped or close to horizontal, we designate an oil chamber or a fully damped gas spring. Although these solutions are not as economical as standard gas springs, they will ensure that your gas springs will last as long as the standard gas springs are used with the face down.
