What’s the application of a dust ring in hydraulic cylinders?
PTFE dust ring is aiming at the bad working conditions of the hydraulic cylinder, a step notch is set at both ends of the pollution absorbing ring after the expansion, and the two ends of the notch is opposite, forming a "Z" shaped structure, which is installed at both ends of the piston of the hydraulic cylinder, the gap at both ends is seamless butt.
The structure of the hydraulic cylinder dust ring can effectively prevent the impurities and high temperature and high pressure air through, has the characteristics of simple structure, and convenient installation, to solve the existing hydraulic cylinder piston seals easily damaged by impurities, tiny hard particles easily adhesion in the piston and wear ring surface scratch cylinder inner chamber and the oil cylinder of high temperature and high pressure air burn out wear ring and piston seal problem, improve the oil Cylinder service life.
