The purpose of a gas spring, also known as a gas strut, is to support or counterbalance dynamic masses. They are commonly used in various applications where there is a need to provide support or balance to moving parts. Gas springs typically contain nitrogen gas, which is inert and non-flammable, making it a preferred choice for their operation.

2. What are the advantages of gas springs?

Gas springs offer several advantages, including the ability to generate greater force in confined spaces, immediate contact force, a wider range of force and stroke options, and easy adjustability of force by changing the pressure. These features make gas springs a versatile solution for applications that require controlled and precise movement.

3. What is the lifespan of a gas spring?

The lifespan of a gas spring depends on how frequently it is opened and closed. On average, a gas spring can be operated around 40,000 times. For example, a gas spring used in a kitchen cupboard can typically remain functional for 3-5 years, considering regular usage.
