1. Processing process of ferrule: the processing of bearing inner ring and outer ring is different according to different raw materials or blank forms, among which the process before machining can be divided into the following three types, The whole processing process is: bar or tube (some bars need to be forged, annealed and normalized) --- machining -- heat treatment -- grinding -- fine grinding or polishing -- final inspection of parts -- rust prevention -- warehousing (to be assembled and matched)

2. The processing process of steel ball and the processing of steel ball are also different according to the state of raw materials. Among them, the process before grinding or polishing can be divided into the following three types: the process before heat treatment, It can also be divided into the following two types. The whole processing process is: cold punching of bar or wire rod (some bar materials need to be punched with ring and annealed after cold punching) - filing, rough grinding, soft grinding or smooth ball - heat treatment - hard grinding - fine grinding - fine grinding or grinding - final inspection grouping - rust prevention, packaging - warehousing.

3. The processing process of roller is different according to the different raw materials. The process before heat treatment can be divided into the following two types, The whole processing process is as follows: after turning bar stock or cold upsetting wire rod, string ring belt and soft grinding - heat treatment - string soft spot - 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 and matched).

4. The machining process of the cage can be divided into the following two categories according to the different design structure and raw materials:

(1) Sheet metal → cutting → punching → stamping forming → shaping and finishing → pickling or shot peening or stringing → final inspection → rust prevention, packaging → warehousing (to be assembled and matched)

(2) Machining process of solid cage: the machining process of solid cage is different according to different raw materials or rough defects. Before machining, it can be divided into the following four types of rough, The whole processing process includes: bar stock, pipe stock, forging, casting - inner diameter, outer diameter, end face, chamfering - Drilling (or broaching, boring) - Pickling - final inspection - rust prevention, packaging - warehousing (to be assembled and matched).
