3, NSK bearing goods before the quality inspection, what preparations need to be done, why do these preparations;

4. Under what conditions, the various inspection items of NSK bearing products are tested by what method and what instruments are used, and the results of the inspection must be within the tolerance range;

What kind of sampling plan should be used and how many quantities should be taken for inspection, in order to more comprehensively and reliably represent the quality of all commodity bearings, and test The results are then measured against what criteria to determine whether the goods are acceptable for approval or for non-conforming batches that should be rejected.

Acceptance inspections for NSK bearings can generally be divided into three categories, namely:

Routine inspection: A routine inspection of routine NSK bearings when they arrive.

Routine inspection: Inspect the NSK bearing and assembly related dimensional accuracy, rotation accuracy, bearing clearance and bearing residual strength.

Special inspection: Check the vibration quality, noise quality and other special requirements of the bearings of NSK bearings.

The above is the relevant content of the NSK bearing inspection and acceptance instructions. Knowing this, inspection and acceptance work will not be impossible, especially when encountering large quantities of products, there is no certain way, the work efficiency will inevitably be reduced, and it is not good to carry out .
