Dust ring is installed in the hydraulic cylinder, when the piston rod is retracted system for scraping dirt on the piston rod, miscellaneous grains, debris and moisture, prevent pollution hydraulic medium, otherwise it will damage the wear ring seals and other components.

Depending on the application and sealing system to use the single-acting and double-acting dust ring, their function is completely different: the single action designed to prevent dust ring outside contaminants Another double-acting wiper seal system optimization function and wipe away the remnants of the film, to avoid any external leaks.

In order to meet the different requirements of technical and economic aspects, there are various dust ring, which have been optimized geometry, using high quality materials.

Advantage

- Good static sealing and thermal expansion compensation

- Friction and heat a small

- Extremely compact design

- Radial force is small, small starting torque

- Suitable for scraper ring
