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:

Bearing can choose diversity of greases. According to the different work environment and bearing operation conditions, we used the following list of grease, in order to convenience for clients to choose. Besides these greases of the listed below, can also add other greases according to the requirements of our customers.
