Rolling the manufacturing process

Although many types of rolling bearings , the structure type , tolerance levels , material selection , processing methods are different, but the basic manufacturing process contains the following:
Bearing parts manufacturing - bearing parts inspection - bearing parts demagnetization , cleaning , rust - bearing assembly - finished bearing checking - finished bearing demagnetization , cleaning - Bearing refined product storage hopper oiled packaging .
Rings are bearing the important parts , because a wide variety of bearing , the Backing bearings rings so that different types of size , structure, manufacturing equipment used, different process methods . Also, because the ferrule machining process more complex process, requiring high precision , so the quality of the backing bearings ring machining accuracy , life and performance has a significant impact .
The raw material for the manufacture of a cylindrical ferrule bar or tube feeding , according to the currently forming process is different , bearing rings generally have the following manufacturing processes.
1 ) ( bar ) cutting - Forged - annealing ( or normalized - Turning ( Cold Rolling Forming ) - heat quenching and tempering - Grinding - parts inspection - demagnetization , cleaning - Submit assembly
2 ) ( bar , tube feeding ) Cutting - Cold Rolling Forming - heat quenching and tempering - Grinding - parts inspection - demagnetization , cleaning - Submit assembly
3 ) ( tube feeding ) cutting - turning forming - heat quenching and tempering - Grinding - parts inspection - demagnetization , cleaning - Submit assembly
4 ) ( bar ) Cutting - cold ( warm ) Extrusion - Turning - heat quenching and tempering - Grinding - parts inspection - demagnetization , cleaning - Submit assembly
