Rolling bearing remanufacturing - — Classification method

Rolling bearing remanufacturing - — 2020 - classification method 01 - 12 the object of the rolling bearing remanufacturing is already used ( Or store unused for a long time) Bearing, due to the use of cycle number, application condition difference, its status difference is bigger, manufacturing plants need for bearing remanufacturing in the first grade. Professional bearing manufacturer again accumulated a large number of practical experience, formed a relatively detailed bearing remanufacturing hierarchical way. Table 1 bearing remanufacturing grading form and content to Schaeffler FAG remanufacturing classification, for example, Level Ⅰ bearing cleaning, disassembly and parts inspection; Level Ⅱ refers to parts surface polishing treatment of minor defects, the Level does not replace any parts; Level Ⅲ refers to the raceway obvious defects, on the grinding and replace roller; Level Ⅳ flaws or depth of crack fatigue refers to the ring, the need to change the ring, rolling body, cage, etc. Schaeffler FAG clear Level Ⅳ remanufacturing cost and the new bearing is close to, only for special bearing to carry out in the field of the levels of remanufacturing. Many domestic bearing factory has carried out bearing manufacturing business again, but did not see a special classification method of technical data. Which related with the remanufacturing industry status quo of domestic bearing industry, domestic bearing remanufacturing industry scattered, lack of specialized manufacturing plants again, to carry out technology research is focused on the technological aspect. Due to differences in remanufacturing object state, bearing remanufacturing process is closely related with classification method, its process flow and its correlation with remanufacturing classification as shown in table 2.
