Double Lip TC NBR rubber Oil Seal
Material:
1.acrylonitrile-butadiene rubber (NBR)
2.fluorine rubber (FPM)
3.silicone rubber, rubber, acrylic acid rubber (ACM/AEM)
4.polyurethane rubber
5.Ptfe rubber etc
Material | Specialty of Oil Seal |
NBR | Mineral oil resistance, good abrasion resistance, Use wide if oil seal, but not used in ketone and lipid polar solvents |
HNBR | Keep the feature of NBR, Heat Resistance, Oil Resistance and Weather Resistance are better than NBR |
ACM | Keep the same Oil Resistance than NBR, Heat Resistance is a little bad than VMQ, but the Weather Resistance is better, Alkali and water Resistance is badder than NBR and other Rubber |
VMQ | Combining well heat Resistance, cold and weather Resistance, but alkali and water Resistance is badder than other Rubber |
FKM | Heat Resistance is better than VMQ, better oil and chemical Resistance,It's the best type of Oil Seal with Rubber performance balance in various Rubber |
EPDM | Good water Resistance, Polarity solvent resistance, Inorganic medicines Resistance and weather Resistance. But the oil Resistance is bad. |
SBR | Good Polarity solvent resistance, weather Resistance |
PTFE | Heat resistance, Cold resistance, chemical resistance, weather resistance is best,Low friction coefficient of the material difference with oil seal |
Fibre | The main material is synthetic fibre, the heat resistance and Loose resistance is better than all along Felt materials |
Application:
1, prevent sediment, dust, moisture and the invasion of the bearing;
2, limit the lubricating oil bearing leaks out.
3, The requirements of oil seal is size (inner diameter and the diameter and thickness) shall conform to the regulations;
4, Require appropriate flexibility, can properly gets stuck, shaft sealing function;
5, Resist heat, the wear-resisting, strength, excellent medium (oil or water),
6, long service life
