Description

1. 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

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:

3.Also can consult the table below choose bearing clearance

The usage situation Use examples Choose clearance
Strict control noise, vibration installation precision, high position Instrument and equipmentRoll neck calender Low noise and small motor C2,C0
General load, speed, working temperature is not high Transmission machinery, reducer and other general machinery C0
High temperature, high speed, high requirements for service life Automobile generator and engine C3
Using high temperature environment, should not be the occasion of heat Drying machine, paper making machinery, and so on C3,C4
High temperature, high speed, and large impact load

Vibrating screen, speed gear

 C4
Inner and outer ring take the surplus interference, large volume, high temperature, heat dissipation Vibration type pressure road, machine car rear wheel C5
