1.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

2.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:
