Judging the quality of a gas spring is mainly considered from the following aspects: First, its sealing property, if the sealing is not good, oil leakage and gas leakage will occur during use; secondly, accuracy, such as 500N is required. Gas springs, some manufacturers produce a force error of no more than 2N, some manufacturers' products may be far from the actual need of 500N; again is the service life, its service life is calculated by the number of times it can fully expand; the last is The force value in the stroke changes, and the ideal gas spring should maintain the same force value throughout the stroke. However, due to design and processing factors, the force value of the gas spring in the stroke inevitably changes. The magnitude of the change is an important criterion for measuring the quality of a gas spring. The smaller the magnitude of the change, the better the quality of the gas spring, and vice versa!
