Introduces a judgment NMB import describes the main points of the bearing can be used again

Analysis judgment import bearings NMB can again use describes the main points of the judgment can import bearings NMB use again, according to the damage degree of import bearings NMB, mechanical properties, importance, and operating conditions, the factors related to inspection cycle to decide. But check if found any of the following defects, the bearing can't continue to use, need to replace the new import bearings NMB. ( a) Inner ring and outer ring, rolling body, any has a crack or breach in a cage. ( b) A: do you have any ring, rolling body fracture. ( c) Rolling surface, guard, has obvious scratches on rolling element. ( d) Cage wear obviously, obviously loose or rivet. ( e) On the raceway surface, rolling body is rust or scar. ( f) On the raceway surface, rolling body has serious indentation or bruised. ( g) Inner ring diameter or outer diameter surface has obvious creep. ( h) Obvious color change due to overheating. ( i) The suzhou import bearing grease sealed, sealing ring or dust cover seriously damaged. NMB imported bearing retainer materials required by the performance: 1. Good dimensional stability and mechanical strength 2. In addition, also need good workability. According to different purposes and demands of its, impact resistance, heat resistance, good corrosion resistance. NMB imported bearing retainer materials: stamping materials, use of low carbon steel. According to different purposes, also used brass, stainless steel plate. Cutting system maintains a material, the use of high-intensity brass, carbon steel, and also the use of synthetic resin.
