While gas springs and hydraulic dampers, specialized kinds 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 required spring force and also the effective stroke from the spring. Application design considerations of the gas springs involves selecting springs with the right sized cylinder and piston depending on the force needed for the application. As an example, the back lid of the car is supported by two gas springs on either side with the lid, that if compressed create a force that's roughly equivalent to the body weight of the lid. Similarly for an chair, the force created by the gas lift should be somewhat higher compared to the weight from the chair, allowing the user to effortlessly slowly move the chair up and down. Furthermore, to avoid buckling the buckling from the gas springs, the force produced ought to always be consistent with its centerline, designed for a gas spring ball stud.


Another good point while selecting or designing a gas spring is the ambient operating temperature, as both extreme cold and hot temperatures modify the operation. The modification in temperature affects pressure that the gas spring can exert and thus 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 closing and opening 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 ought to be ensured while designing the cylinder as well as the piston. Special features, for example external locking and variable damping, ought to be considered. Safety is another major factor that should be thought about while producing gas springs. As a part of this factor, the suitability from the spring and also the mounting position strength are taken into consideration. Additionally, a second secure can be incorporated for safety purposes, if neccessary.

While mounting a gas spring, care needs to be taken to make sure that they're mounted in a upright fashion with the piston rod pointed downwards. This really is to ensure that the rod seal is kept lubricated constantly. If the spring is to be mounted at an angle, care should be taken to ensure that the level of the lubricating oil is plenty for your rod seal being always lubricated throughout the operation.
