The automobile hydraulic support rod is made of thick stainless steel, which has the characteristics of high pressure , not easy to deform, corrosion resistance, high temperature resistance and so on. The surface of the travel rod is treated with QPQ, the surface friction is small, wear-resistant, , without points, and there will be no jamming during the expansion and contraction process. The spring uses high-pressure inert 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 resistant to wear and rust, and has a 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.
