Problems solved by technology

[0002] With the development of society, the application of hydraulic cylinders in heavy industries is particularly important, not only because of the stable operation of hydraulic cylinders, long service life, and high economic benefits, but hydraulic cylinders also have very strict environmental requirements, especially in areas with corrosion In the atmosphere of aggressive gas or liquid, and the surface of the hydraulic cylinder is severely worn, which seriously affects the service life and appearance of the hydraulic cylinder. Therefore, a hydraulic cylinder with strong friction resistance is needed to increase its service life and save costs.
