1. Sealing: If the sealing effect of the gas spring becomes poor, there will be oil leakage and air leakage. Therefore, it is necessary to choose a regular gas spring produced by a regular manufacturer, and be sure to check the tightness, so that there can be no problems.
2. Accuracy: For example, a gas spring of 500N is required. The N should be as small as possible. For example, Zhongze gas spring manufacturer, the error is controlled within 1-2N, which is the best gas spring standard in the industry.
3. Service life: The service life is calculated by the number of times it can be fully retracted. The manufacturer can be asked to test the number of uses of the gas spring. In this regard, we can also give a test report.
4. The force value change during the stroke: the smaller the change range, the better the quality; on the contrary, the larger the change range, the worse the quality.
