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 |
