The bearing structure is mainly composed of raw materials, bearing inner and outer rings, steel balls and cages.

Bearing production process flow:

Bearing raw materials - inner, steel ball or roller processing, outer ring processing, cage (stamping or solid) processing - bearing assembly - finished bearings.

Bearing inner and outer ring process flow:

Bar material - blanking - forging - spheroidizing annealing - turning - heat treatment - grinding - super finishing - final inspection of parts - rust prevention and storage.

Steel ball processing process:

Cold punching of bars or wires (some bars need to be punched and annealed after cold punching) - Frustration, soft grinding or light ball - Heat treatment - Hard grinding - Fine grinding - Fine grinding or grinding - Final inspection grouping - rust prevention, rough grinding, packaging - storage (to be assembled).

Roller processing process:

After bar turning or wire cold heading, ring belt stringing and soft grinding - heat treatment - soft spot stringing - 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 assembled).

Cage processing process:

Cast copper parts - inner diameter, end face, chamfering - drilling (or drawing, boring) - deburring - pickling - final inspection - rust prevention, outer diameter, packaging - storage < Ready to be assembled>.
