The miniature bearing expires three intrinsic reason - IKO bearing Shanghai source melts technology center analysis bearing decision import bearing quality and so on structural design, manufacture craft and material quality three big factors.
Miniature bearing structural design reasonable at the same time has has the sophistication, only then can have the long IKO bearing life.The bearing manufacture must pass through generally forging, the heat treatment, the turning, the grinding and the assembly and so on the multi-channel processing working procedure.Each processing craft rationality, the sophistication, the stability also can affect the bearing life.Influence end product bearing quality heat treatment and the abrasive machining working procedure, often has with the bearing expiration more direct relations.In recent years indicated to the IKO bearing active face deterioration level research that, the grinding craft and the bearing surface quality relations are close.
The miniature bearing material metallurgy quality once was affects the IKO bearing early failure the primary factor.Along with metallurgy technology (e.g. bearing steel vacuum degasification and so on) the progress, raw material quality is improved.Raw material quality factor the proportion which occupied in the bearing expiration analysis already obviously drops, but it still was one of major effect factors which the IKO bearing expired.Whether the selection appropriate still was a factor which the bearing expiration analysis must consider.
The miniature bearing expiration analysis primary mission, is according to the massive background material, the analysis data and the expiration form, discovers creates the primary factor which the IKO bearing expires, in order to have pointed proposed the improvement measure, lengthens the bearing the enlistment period, avoids the bearing having the burst characteristics early failure.
