Materials of Bearing Seals
Bearing seal form into dust cover and plastic material seal. There are various types of seal. Because of different seal material, bearing to adapt condition will also change.
| Name Code | Characteristics | Using Temperature |
NBR Acrylonitrile-butadiene rubber | Oil resistance,heat resistance,resistance to wear | -40~120 |
FKM Fluorine rubber | Hear resistant,acid and alkali resistant and chemicals, oil resistance preferred | -20~200 |
VMQ Silicone rubber | Heat and cold resistance, good compression deformation is small, but the mechanical strength is not good | -60~230 |
ACM Polypropylene acid ester rubber | Heat resistance, oil resistance better than NBR, but resistance to water and alkali is not strong | -20~150 |
