(2) What are the items for the inspection of KOYO's imported bearing products; in order to check these items,
(3) KOYO imported bearing products before the quality inspection; what preparations need to be done; in order to do these preparations,
(4) The inspection items of KOYO imported bearing products are under the conditions of å•¥; using å•¥ method; using å•¥ instruments for inspection; the results of inspection must be qualified within the scope of public service.
(5) KOYO imported bearing products are sometimes in large quantities; it is impossible to conduct 100% inspection; then, the sampling plan should be selected; the number of samples should be selected for inspection; the talents should be more fully and satisfactorily represent the quality of the overall commodity bearing; The results of the inspection are also measured according to the standard; to determine whether the goods are acceptable batches; or the unqualified batches that should be rejected.
Profession professor analysis: KOYO imported bearings can be generally divided into three categories; namely:
Routine view - a general view of the routine of KOYO imported bearings when they arrive.
Customs view the KOYO imported bearings and equipment related scale accuracy, rotation accuracy, bearing clearance and bearing residual magnetic strength and other items to view.
Special View - View the oscillation quality, noise quality and other special requirements for bearings of KOYO bearings.
And how to distinguish whether the quality of a bearing can pass; often there are some simple identification methods; but it may be careful; this may not be correct in some cases. Professional professors here list us three.
1. I feel the quality of KOYO imported bearings through the appearance. I found many customers in the process of selling KOYO bearings. Only the external light of the bearing is good quality; this is wrong. The brightness of the bearing should be black and bright; The reason for the brightness is that the steel used in the bearing can be qualified and its grinding process and the cutting fluid used, etc.;
2, chamfering can be bright KOYO imported bearing chamfer does not determine the quality of the bearing; but it reflects the bearing processing method. The chamfer is black; clarify the heat treatment by quenching; this adds the hardness of the bearing; and some people think that it is down The angle is black and the good looks are not processed thoroughly; this is a misunderstanding.
3, one cage is better than the two; although the new process uses an integrated cage; but it only saves data; and the performance of the reverse is worse than the two.
In general, the service life of KOYO bearings is related to three elements; one is the quality of the bearing itself. The second is the use of the environment. The third is the installation method.
