While gas springs and hydraulic dampers, specialized kinds of springs that utilize gas under compression to exert force, are produced in different sizes and lengths, selecting one depends upon two main factors, the mandatory spring force and the effective stroke from the spring. Application design considerations with the gas springs involves selecting springs with the right sized cylinder and piston depending on the force required for the application. As an example, a corner lid of a car is based on two gas springs on both sides with the lid, which when compressed create a force which is roughly equivalent to the weight from the lid. Similarly to have an office chair, the force made by the gas lift needs to be a little higher than the weight from the chair, allowing the consumer to effortlessly slowly move the chair up and down. Furthermore, to avoid buckling the buckling of the gas springs, the force produced should invariably be in line with its centerline, designed for a strut bracket.


Another good point while selecting or designing a gas spring will be the ambient operating temperature, as both extreme hot and cold temperatures affect the operation. The alteration in temperature affects the pressure that the gas spring can exert and therefore the output force. At quite high temperatures, the seal permeability increases and gas molecules may escape from the seal quicker. They are also designed based on the performance guidelines that include cold closing and opening efforts, hot closing and opening efforts, self-rise and self-close angle, hump, room temperature, and damping.

Resistance to dents, damage, and abrasion also need to be ensured while designing the cylinder and also the piston. Special features, including external locking and variable damping, also need to be considered. Aspects another major component that should be thought about while producing gas springs. As a part of this factor, the suitability with the spring and the mounting position strength are taken into consideration. Furthermore, another locking mechanism may also be incorporated for safety purposes, if needed.

While mounting a gas spring, care ought to be come to ensure that they are mounted in a upright fashion with all the piston rod pointed downwards. This can be to ensure that the rod seal is kept lubricated all the time. When the spring is usually to be mounted in an angle, care needs to be taken to ensure that the amount of the lubricating oil is enough for the rod seal being always lubricated throughout the operation.
