The Inspection Process is as above:

The Production Process is as follows :

An ordinary ball bearing, mainly by the ring, the inner ring , outer ring, balls , cage , dust cover six components,

1.Processing flow billet outer storage --- pickling --- blanking --- capillary cooling --- ball --- pickling phosphating --- --- --- drawing --- annealing saponification --- pipe Inspection --- total --- Ruanmo blanking end face chamfered --- heat treatment --- --- --- end face grinding mill grind the outer diameter of the outer diameter --- --- roller mill channel - - ultra- lapping channel .

2.Machining billet inner storage --- --- hot pickling --- blanking capillary wear --- check --- pickling cold saponification --- --- phosphating --- drawing --- annealing --- total seizure steel blanking --- --- --- polishing polishing end face chamfered outer diameter --- --- car ditch --- heat treatment --- grinding mill outside diameter of the end surface --- --- rolling mill grind the outer diameter --- channel --- Superfinishing channel --- finishing outside diameter.

3.Ball

The town no balls professional manufacturer , have adopted outsourcing .

4.Cage Processing

Metal storage --- Cutting --- forming --- shaping

5.Shuttered processing

Metal storage --- Cutting --- typing --- forming --- shaping

6.After these five components ready for assembly, the process is as follows :

( 1 ) The inner and outer rings , balls , cage four parts into semi- bearing assembly lines carry the initial installation .

( 2 ) The initial installation of bearings, seals, dust cover, into the second track lines, the bearing assembly into finished products .

( 3 ) product testing .

( 4 ) Finished seal.

( 5 ) product storage
