While gas springs and hydraulic dampers, specialized types of springs that utilize gas under compression to exert force, are made in assorted sizes and lengths, selecting one is dependent upon two main factors, the mandatory spring force and the effective stroke of the spring. Application design considerations of the gas springs involves selecting springs with the proper sized cylinder and piston based on the force required for the applying. For instance, the back lid of your car is based on two gas springs on both sides of the lid, that if compressed create a force that is roughly equal to the load of the lid. Similarly for an chair, the force produced by the gas lift needs to be a better view than the weight with 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 ought to always be in line with its centerline, for a 10mm ball stud.


Another point to consider while selecting or designing a gas spring may be the ambient operating temperature, as both extreme cold and hot temperatures get a new operation. The change in temperature affects pressure that the gas spring can exert and therefore the output force. At high temperatures, the seal permeability increases and gas molecules may escape with the seal easier. Also, they are designed in line with the performance guidelines that include cold opening and closing efforts, hot opening and closing efforts, self-rise and self-close angle, hump, room temperature, and damping.

Capacity dents, damage, and abrasion should also 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 factors are another major factor that is highly recommended while producing gas springs. As an element of this factor, the suitability from the spring and the mounting position strength are taken into account. In addition, a second secure may also be incorporated for safety purposes, if needed.

While mounting a gas spring, care should be taken to ensure that they're mounted in a upright fashion with the piston rod pointed downwards. This can be to make sure that the rod seal is kept lubricated all the time. When the spring is to be mounted in an angle, care needs to be taken up ensure that the level of the lubricating oil is sufficient for the rod seal being always lubricated during the operation.
