What Is Dust Ring

The main function is to remove dust, sand, rain and frost attached to the outer surface of the cylinder by the reciprocating piston rod, and prevent external dust and rain from entering the inside of the sealing mechanism. A good dust ring should have a sharp lip structure and a low coefficient of friction. This can prevent external dust from entering the system and also reduce the wear of the equipment.

Dust rings are mainly used for oil cylinders or drive shafts, such as DSH PTFE dust rings, which use PTFE ring and O-ring structure to prevent dust from oil cylinders in harsh environments and have self-lubricating properties. At the same time, it can protect the cylinder piston from being damaged by dust.
