The dust ring, the main role is to remove the reciprocating movement of the piston rod in the cylinder exposed on the external surface attached to the dust, sand, rain and frost and other dirt, prevent external dust, rain water into the internal sealing mechanism. A good dustproof ring should be a sharp lip type structure with low friction coefficient, which can prevent the dust from entering the system and reduce the friction of the equipment.

application area

The utility model is used for an oil cylinder or a transmission shaft, such as a PTFE dust ring of a de O, a dustproof ring with a PTFE framework and a ring type structure, which can be used in the environment of a bad oil cylinder, and has the self-lubricating property. At the same time can protect the cylinder piston is not dust damage. Combination sealing high quality cylinder seal.
