The automobile hydraulic support rod is made of thick stainless steel, which has the characteristics of high pressure bearing, not easy to deform, resistance, high temperature resistance and so on. The of the travel rod is treated with QPQ, the friction is small, wear-, smooth, without blunt points, and there be no jamming during the expansion and contraction process. The gas spring uses high-pressure inert gas as power, the support force is constant during the entire working stroke, and has a buffer mechanism to avoid the impact, which is the biggest feature superior to ordinary springs. The use of integrated molding technology makes the hydraulic rods have better sealing performance, uses high-quality hydraulic oil, is to wear and rust, and has a longer service life. The design is reasonable, there is no need to punch holes during installation, and the installation is convenient. Only one can be installed in a few minutes. It is safe to use and requires no maintenance.
