How To Judge The Quality Of Gas Springs

Judging the quality of a gas spring is mainly from the following aspects: first, its sealing, if the sealing is not good, there will be oil leakage, air leakage and other phenomena during use; second is the accuracy, such as the need for 500N For gas springs, the force error produced by some manufacturers does not exceed 2N, and the products of some manufacturers may be far from the actual required 500N; again, the service life is calculated by the number of times it can be fully expanded; The force value changes during the stroke. Ideally, the force value of the gas spring should remain the same throughout the stroke. However, due to design and processing factors, the force value of the gas spring during the stroke inevitably changes. The magnitude of its 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.
