sealing ring is composed of one or a few parts of the annular cover, a fixed to the bearing ring or washer on and contact with another ring or washer or form a labyrinth of narrow gap and prevent the lubricating oil leakage and outside intrusion.
Sealing ring is a kind of cross section for the circular rubber ring, because its cross section is type O, so called type O sealing ring.
Take you to discuss several common seal ring have what kind of?
A nitrile rubber, NBR sealing ring is suitable for oil and hydraulic oil, glycol hydraulic oil, the second ester lubricating oil, gasoline, water, silicone grease, silicone oil and other medium.
Is currently the most useful, the lowest cost of rubber seal, also often have a second, HNBR hydrogenated nitrile rubber sealing ring has excellent corrosion resistance, tensile and compression deformation characteristics, resistance to ozone, sunshine, good weather resistance.
Has better wear resistance than nitrile rubber sealing ring.
Suitable for washing machine, automobile engine system.
Three, SIL silicon rubber seals
sealing ring with heat resistant, cold resistant, resistant to ozone, atmospheric aging resistance performance.
Have good insulation performance.
Suitable for household appliances such as electric water heater, electric iron, and microwave ovens, VITON fluorine rubber seal of high temperature resistance is better than that of silicone rubber, has excellent weather resistance, ozone resistance and chemical resistance, cold resistance is poor.
Suitable for diesel engine, fuel system and chemical plant of sealing requirements.
Five, FLS fluorine silicon rubber seals sealing ring its performance has both the advantages of the element fluorine rubber and silicone rubber, oil resistance, solvent resistance, resistance to fuel oil and the high and low temperature resistance are good.
Can resist oxygen containing compounds, containing aromatic hydrocarbon solvent and erosion of chlorinated solvents.
Six, EPDM EPDM rubber sealing ring has good weather resistance, ozone resistance, water resistance and chemical resistance.
Can be used for alcohols and ketones, can also be used for the seal of high temperature steam environment.
- generally use temperature range
