Bearing production process

Process flow of inner and outer rings of bearings:
Bars - unloading - forging - spheroidizing annealing - turning - heat treatment - grinding - super finishing - final inspection of parts - rust prevention and storage.
Processing process of steel balls:
Cold punching of bars or wires (some bars need to punch rings and anneal after cold punching) - filing, soft grinding or polishing - heat treatment - hard grinding - fine grinding - fine grinding or grinding - final inspection and grouping - rust prevention, rough grinding, packaging - storage (to be assembled).
Processing process of rollers:
Bars are turned or wires are cold headed and then rings and soft grinding are added - heat treatment - soft points are added - rough grinding of outer diameter - rough grinding of end face - final grinding of end face - fine grinding of outer diameter - final grinding of outer diameter - final inspection and grouping - rust prevention, packaging - storage (to be assembled). The processing process of the cage:
Copper castings - turning inner diameter, end face, chamfering - drilling (or boring) - deburring - pickling - final inspection - rust prevention, outer diameter, packaging - storage (to be assembled).
