While gas springs and hydraulic dampers, specialized kinds of springs that utilize gas under compression to exert force, are designed in assorted sizes and lengths, selecting one is dependent upon two main factors, the required spring force as well as the effective stroke with the spring. Application design considerations with the gas springs involves selecting springs with the appropriate sized cylinder and piston based on the force required for the application form. For instance, the trunk lid of a car is supported by two gas springs on each side with the lid, that when compressed create a force that's roughly equal to the weight with the lid. Similarly to have an office chair, the force produced by the gas lift should be a little higher than the weight from the chair, allowing the user to effortlessly move the chair up and down. Furthermore, to stop buckling the buckling from the gas springs, the force produced should always be consistent with its centerline, particularly for a gas spring mounting 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 modification in temperature affects pressure a gas spring can exert and consequently the output force. At very high temperatures, the seal permeability increases and gas molecules may escape from the seal quicker. Also, they are designed depending on the performance guidelines that include cold opening and closing efforts, hot opening and closing efforts, self-rise and self-close angle, hump, 70 degrees, 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, ought to be considered. Aspects another major component that should be considered while producing gas springs. As a part of this factor, the suitability of the spring and also the mounting position strength are considered. Furthermore, a secondary fasten can be incorporated for safety purposes, if neccessary.

While mounting a gas spring, care should be come to make certain that they may be mounted in an upright fashion with all the piston rod pointed downwards. This is to ensure the rod seal is kept lubricated constantly. When the spring will be mounted in an angle, care ought to be taken to make certain that degree of the lubricating oil is enough for the rod seal to be always lubricated throughout the operation.
