While gas springs and hydraulic dampers, specialized kinds of springs that utilize gas under compression to exert force, are made in a variety of sizes and lengths, selecting one depends on two main factors, the required spring force and the effective stroke of the spring. Application design considerations of the gas springs involves selecting springs with the right sized cylinder and piston based on the force necessary for the application. As an example, the trunk lid of a car is supported by two gas springs on either side of the lid, which when compressed produce a force which is roughly comparable to the weight of the lid. Similarly for an office chair, the force produced by the gas lift needs to be a little higher than the body weight from the chair, allowing the user to effortlessly move the chair down and up. Furthermore, to prevent buckling the buckling of the gas springs, the force produced ought to always be in line with its centerline, particularly for a slender gas spring device.

Another factor to consider while selecting or designing Gas Spring Ball Stud is definitely the ambient operating temperature, as both extreme hot and cold temperatures change the operation. The change in temperature affects the stress which a gas spring can exert and consequently the output force. At very high temperatures, the seal permeability increases and gas molecules may escape with the seal quicker. They are also designed based on the performance guidelines that include cold closing and opening efforts, hot closing and opening efforts, self-rise and self-close angle, hump, room temperature, and damping.

As opposed to most other kinds of springs, gas springs use a built in pretension force and a flat spring characteristic. Because of this there is just a small difference in force between full extension and full compression.

Because the piston and piston rod are pressed to the cylinder, volume reduces and pressure increases. This causes pushing force to increase. In conventional gas-type springs, this increase is usually around 30% at full compression.

The pushing spring movement is slow and controlled. It is reliant on the gas flow involving the piston sides being able to go through channels within the piston throughout the stroke. Conventional gas springs use ‘hydraulic damping’, which involves a tiny amount of oil slowing the rate from the stroke immediately before the spring reaches full extension. This offers the movement a braking character at the conclusion position so long as the piston rod is in the downward direction.

Resistance to dents, damage, and abrasion also need to be ensured while designing the cylinder as well as the piston. Special features, including external locking and variable damping, ought to be considered. Safety is another major factor that should be considered while producing gas springs. As an element of this factor, the suitability of the spring as well as the sldvml position strength are considered. In addition, a secondary locking mechanism can be incorporated for safety purposes, if required.

While mounting a gas spring, care needs to be taken to ensure these are mounted inside an upright fashion using the piston rod pointed downwards. This is to ensure that the rod seal is kept lubricated constantly. If the spring is to be mounted at an angle, care needs to be taken to ensure that the level of the lubricating oil is sufficient for that rod seal to become always lubricated throughout the operation.
