What is the material of the dust ring

The dust ring is a reciprocating seal used to prevent external dust from mixing into the hydraulic cylinder. The common dust ring materials are as follows:

Rubber dust ring: Rubber dust ring is the most widely used material, it has good elasticity and plasticity, can adapt to a variety of different shapes and sizes of electronic equipment jack, but also has a certain cushioning and shock absorption effect.

Fluorine rubber dust ring: fluorine rubber dust ring is a high-performance material, with corrosion resistance, oxidation resistance, high temperature resistance, chemical resistance and other characteristics, widely used in chemical industry, aviation and other fields.

Polytetrafluoroethylene (PTFE) dust ring: PTFE dust ring is a kind of seal made of polytetrafluoroethylene, which is widely used in various mechanical sealing occasions because of its excellent chemical resistance, low friction coefficient and good self-lubrication performance.

In addition, the dust ring can also use other materials, such as polyurethane (PU), polyamide (PA), etc., the specific choice depends on the application environment and requirements. When selecting the dust ring, it is necessary to consider its wear resistance, corrosion resistance, high temperature resistance and other factors to ensure that it can effectively prevent dust and pollutants from entering the hydraulic cylinder and ensure the normal operation of the equipment.
