While gas springs and hydraulic dampers, specialized types of springs that utilize gas under compression to exert force, are designed in different sizes and lengths, selecting one depends upon two main factors, the mandatory spring force as well as the effective stroke of the spring. Application design considerations from the gas springs involves selecting springs with the appropriate sized cylinder and piston based on the force required for the application form. As an example, the back lid of the car is sustained by two gas springs on either side with the lid, that if compressed make a force which is roughly comparable to the weight with the lid. Similarly with an desk chair, the force produced by the gas lift should be a little higher compared to the weight with the chair, allowing the user to effortlessly move the chair up and down. Furthermore, to prevent buckling the buckling from the gas springs, the force produced ought to always be in line with its centerline, for a 10mm ball stud.


Another factor to consider while selecting or designing a gas spring may 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 very high temperatures, the seal permeability increases and gas molecules may escape with the seal easier. They are also designed based on the performance guidelines which include cold closing and opening efforts, hot opening and closing efforts, self-rise and self-close angle, hump, 70 degrees, and damping.

Potential to deal with dents, damage, and abrasion also need to be ensured while designing the cylinder as well as the piston. Special features, such as external locking and variable damping, ought to be considered. Safety is another major component that should be considered while producing gas springs. As part of this factor, the suitability from the spring and also the mounting position strength are taken into consideration. Additionally, a secondary locking mechanism can be incorporated for safety purposes, if needed.

While mounting a gas spring, care needs to be taken to make certain that they may be mounted in an upright fashion with all the piston rod pointed downwards. This really is to ensure the rod seal is kept lubricated at all times. If the spring is to be mounted at an angle, care ought to be taken up be sure that the amount of the lubricating oil is enough for that rod seal being always lubricated during the operation.
