While gas springs and hydraulic dampers, specialized kinds of springs that utilize gas under compression to exert force, are made in different sizes and lengths, selecting one depends upon two main factors, the necessary spring force as well as the effective stroke from the spring. Application design considerations from the gas springs involves selecting springs with the proper sized cylinder and piston in line with the force required for the application form. For example, the back lid of your car is supported by two gas springs on each side with the lid, that when compressed produce a force which is roughly equal to the weight with the lid. Similarly for an office chair, the force created by the gas lift needs to be somewhat higher than the weight from the chair, allowing the user to effortlessly move the chair up and down. Furthermore, to stop buckling the buckling of the gas springs, the force produced should invariably be consistent with its centerline, for a strut bracket.


Another good point while selecting or designing a gas spring is the ambient operating temperature, as both extreme cold and warm temperatures modify the operation. The change in temperature affects pressure that the gas spring can exert and consequently the output force. At quite high temperatures, the seal permeability increases and gas molecules may escape through the seal easier. Also, they are designed in line with the performance guidelines including cold opening and closing efforts, hot closing and opening efforts, self-rise and self-close angle, hump, 70 degrees, and damping.

Potential to deal with 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 is another major factor that is highly recommended while producing gas springs. As part of this factor, the suitability of the spring as well as the mounting position strength are considered. In addition, a secondary fasten can also be incorporated for safety purposes, if neccessary.

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