Production process of bearing structure

Bearing structure is mainly composed of raw materials, bearing inner and outer rings, steel balls (bearing rollers) and cages. What is their production process? Here is the related information.
Bearing production process flow:
Bearing raw materials - inner, steel ball or roller processing, outer ring processing, cage (stamping or solid) processing - bearing assembly - bearing products
Process flow of bearing inner and outer rings:
Bar cutting forging spheroidizing annealing turning heat treatment grinding superfinishing final inspection antirust storage.
The machining process of steel ball is as follows
Cold punching of bar or wire (some bars need punching ring and annealing after cold punching) - cutting, soft grinding or light ball - heat treatment - hard grinding - fine grinding - fine grinding or grinding - final inspection grouping - rust prevention, rough grinding, packaging - warehousing.
Machining process of roller:
After bar car processing or wire cold heading, string ring belt and soft grinding - heat treatment - string soft point - rough grinding outer diameter - rough grinding end face - final grinding end face - fine grinding outer diameter - final grinding outer diameter - final inspection grouping - rust prevention, packaging - warehousing (to be matched).
Machining process of cage:
Cast copper parts - turning inner diameter, end face, chamfering - Drilling (or broaching, boring) - deburring - Pickling - final inspection - rust prevention, outer diameter, packaging - warehousing.
