1. Features :
To bear predominate radial load and subsidiary axial load from both directions, lower cost and price, low running resistance, high limiting speed, possible to reach higher rotating precision and pretty low vibration level, in addition, possible to make into sealing structure.
2. Applications :
Electric motors, machine tools, automobiles, precise devices, home appliances, chemical machineries, general machineries, agricultural machineries, etc
Details
| 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 |
3. 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:

4. 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 |
