While gas springs and hydraulic dampers, specialized kinds of springs that utilize gas under compression to exert force, are designed in various sizes and lengths, selecting one is dependent upon two main factors, the necessary spring force as well as the effective stroke with the spring. Application design considerations of the gas springs involves selecting springs with the right sized cylinder and piston based on the force necessary for the applying. As an example, the trunk lid of the car is based on two gas springs on both sides with the lid, that when compressed create a force that is roughly comparable to the load with the lid. Similarly for an chair, the force created by the gas lift needs to be a little higher compared to the weight with the chair, allowing the user to effortlessly move the chair up and down. Furthermore, to stop buckling the buckling with the gas springs, the force produced ought to always be consistent with its centerline, particularly for a 10mm ball stud.


Another factor to consider while selecting or designing a gas spring is the ambient operating temperature, as both extreme cold and warm temperatures modify the operation. The alteration in temperature affects pressure a gas spring can exert and therefore the output force. At high temperatures, the seal permeability increases and gas molecules may escape from the seal more easily. Also, they are designed in line with the performance guidelines which include cold opening and closing efforts, hot closing and opening efforts, self-rise and self-close angle, hump, room temperature, and damping.

Capacity dents, damage, and abrasion should also be ensured while designing the cylinder and the piston. Special features, including external locking and variable damping, should also be considered. Safety factors are another major component that should be thought about while producing gas springs. As part of this factor, the suitability from the spring and also the mounting position strength are considered. Furthermore, a secondary fasten can also be incorporated for safety purposes, if required.

While mounting a gas spring, care needs to be come to make sure that they're mounted within an upright fashion with the piston rod pointed downwards. This can be to make sure that the rod seal is kept lubricated all the time. In the event the spring will be mounted in an angle, care ought to be taken up make certain that degree of the lubricating oil is sufficient for your rod seal being always lubricated during the operation.
