The production technology and the whole industry are developing, so the quality of the products will be improved, at least needle roller bearings. But although the overall development is good, it can not prevent the appearance of fake and inferior bearing products in the market.

The harm of inferior needle roller bearings is obvious, which will not only cause equipment damage, but also affect the progress of the project. In order to avoid unnecessary economic losses in production, it is necessary to master the skills of correctly identifying fake and inferior needle roller bearings.

Most of the inferior needle roller bearings are produced in irregular production environment, so the manufacturing process of the product itself is certainly very bad, which shows that we can judge from the manufacturing process of needle roller bearings.

Secondly, the quality of needle roller bearings can also be seen from the outer packaging used. For example, as long as we carefully observe whether the manufacturer's label on the outer packing of needle roller bearings meets the complete standard, if it is incomplete, it means that the product quality does not meet the standard.

Next, we should pay attention to the problem of sales channels of needle roller bearing products. If we buy products from regular manufacturers, we seldom buy fake and inferior products. If we buy in some irregular or small markets, the probability of purchasing fake and inferior needle roller bearings will be greatly increased.

In addition, it is necessary to pay attention to the technical level of needle roller bearing manufacturers. If the technology of manufacturers is not mature, the requirement of bearing precision must not meet the standard. As long as we master these points, we will not be afraid to buy fake and inferior needle roller bearings.
