How bearings are made？

The bearing structure is mainly composed of bearing inner and outer rings, steel balls (bearing rollers) and cages. What is their production process, the following is the relevant information.

Bearing inner and outer ring process flow:

Rods-cutting -forging - spheroidizing and annealing - turning - heat treatment - grinding - super finishing - final inspection of parts - rustproofing into storage

Processing process of steel ball:

Light ball - heat treatment - hard grinding - fine grinding - final inspection grouping - rust prevention, packaging - storage

Processing of bearing rollers:

Heat treatment - coarse grinding OD - coarse grinding end face - final grinding end face - fine grinding OD - final grinding OD - final inspection grouping - rust prevention,, packaging - storage

Process of cage:

Cast copper parts - turning inner diameter, end face, chamfering - drilling - deburring - pickling - final inspection - rust prevention, outer diameter, packaging - storage.
