Production process:
1. Abrasive machining of steel pipe;
2. The inner & outer ring grinding;
3. The precision work of inner ring & outer ring
4. Bearing cleaning;
5. The Assembly of inner ring , outer ring , bearing balls &
cage, etc.
6. Bearing inspection( precison, noise & vibration levels).
7. Packing: in plastic tube, then in carton & pallet or in
color single box, then in carton & pallet, or as the customers'
request.
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:

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 |
