Bearing Seal
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 |
The size of bearing clearance directly related to the use of noise, vibration, normal temperature, service life and the assembly of machinery motion effect. Therefore, it is very important that we choose the suitable assembly bearing clearance. We divided from small to big according to radial clearance range into C2, C0, C3, C4 and C5. Specific reference see the chart:
