How Gas Springs Work
A gas filled spring consists of a precision rod attached to a piston moving within a sealed cylinder containing nitrogen at high pressure. Output forces are the result of the differential between the pressure in the cylinder and atmospheric pressure outside the cylinder acting on the cross-section of the rod. As the piston rod is introduced into the cylinder (compression stroke), the internal pressure increases according to the volume of gas displaced by the rod. This increase in Force or K-Factor is normally 5% - 50%. In comparison to mechanical springs, gas springs are almost constant force.
Because they operate on simple pressure differentials, gas springs will perform as well in the vacuum of space as they do on land.
Inventory of Gas Springs
(Click the thumbnail to learn more about the specific gas springs.)
Compression Gas Springs: Compression gas springs are the most common type of gas spring, or gas strut, and are used for standard lifting, opening and counterbalance applications where a contained force device is needed. More about Compression Gas Springs »
Adjustable Locking Gas Springs: Adjustable and safety locking gas springs are used for when the spring must be locked in place unless activated. They secure lifts at a set height or position, ensuring worker safety, the stability of the lift platform or the equipment. More about Adjustable Locking Gas Springs »
Safety Lock Shroud Springs: A safety locking shroud springs that utilize a mechanical locking device to lock the gas spring in a fully extended position. More about Safety Lock Shroud Springs »
Tension Gas Springs: Also referred to as traction springs, these units operate the opposite of compression gas springs; they retract rather than extend. More about Tension Gas Springs »
Stainless Steel Gas Springs: We stock the most popular 316L stainless steel compression gas spring sizes, used for lifting, opening and counterbalance applications that require protection against corrosion or water, or that need to be sanitized. More about Stainless Steel Gas Springs »
Custom Designed Springs: When standard gas springs are not suitable, IGS product specialists will design custom gas springs for your specific application. More about Custom Designed Springs »
Dampers: Unlike gas springs that generate force, dampers are used to control the speed that a lid, guard or hatch opens or closes. They ensure that the equipment does not release too quickly, protecting the equipment and the safety of workers. More about Dampers »
