While gas springs and hydraulic dampers, specialized forms of springs that utilize gas under compression to exert force, are made in various sizes and lengths, selecting one depends on two main factors, the necessary spring force and the effective stroke of the spring. Application design considerations with the gas springs involves selecting springs with the right sized cylinder and piston depending on the force necessary for the application. For example, a corner lid of a car is sustained by two gas springs on both sides from the lid, that if compressed create a force that is roughly equal to the body weight with the lid. Similarly with an desk chair, the force made by the gas lift should be a better view than the weight with the chair, allowing the user to effortlessly slowly move the chair along. Furthermore, to prevent buckling the buckling from the gas springs, the force produced should invariably be in line with its centerline, for a strut bracket.


Another factor to consider while selecting or designing a gas spring may be the ambient operating temperature, as both extreme cold and hot temperatures modify the operation. The change in temperature affects the pressure that a gas spring can exert and thus the output force. At high temperatures, the seal permeability increases and gas molecules may escape through the seal quicker. They're also designed based on the performance guidelines including 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 ought to be ensured while designing the cylinder as well as the piston. Special features, including external locking and variable damping, also need to be considered. Aspects another major factor that should be thought about while producing gas springs. As a part of this factor, the suitability of the spring and the mounting position strength are considered. In addition, a second secure can also be incorporated for safety purposes, if needed.

While mounting a gas spring, care should be taken up make sure that they are mounted within an upright fashion using the piston rod pointed downwards. This really is to ensure that the rod seal is kept lubricated all the time. If the spring is usually to be mounted in an angle, care needs to be taken to make certain that level of the lubricating oil is enough for your rod seal to be always lubricated throughout the operation.
