NTN作为进口轴承品牌质量好有目共睹，但是也有些时候ntn轴承会出现质量问题，其实原因很简单，不要说ntn轴承不好，只能说你买的不是正品ntn轴承。如何辨别ntn进口轴承的真假，在这个时候就非常必要的了。
NTN as the import bearing brand quality is obvious to all to see, but also sometimes NTN bearings will have quality problems, in fact, the reason is very simple, do not say that NTN bearings are not good, you can only say that you buy not the positive NTN bearing. How to distinguish the true and false of NTN imported bearings is very necessary at this time.
一般情况下，正厂品牌的恩梯恩轴承都有自己专门的设计人员对外包装进行设计，并且安排生产条件过关的工厂进行制作生产，因此包装无论从线条到色块都非常清晰，毫不含糊部分恩梯恩品牌的配件包装上还有专门用以保护自己的知识产权的独特设计。

左手握住ntn轴承的轴承体内套，右手拨动外套使其旋转，听其是否有杂响。由于大部分仿冒产品的生产条件落后，完全手工作坊式操作，在生产过程中难免会掺进沙子一类的杂质，藏在轴承体内，所以在旋转的时候会发出杂响。由于国内目前的防锈技术还不是特别到家，所以对轴承体进行防锈处理时很容易留下厚厚的油迹，拿在手上粘稠，而国外原装ntn的轴承上几乎看不到防锈油的痕迹，倒是特别细心的行家说ntn轴承闻起来有一种味道，肯定是下了防锈油，只是看不到而已。
The left hand holds the bearing sleeve of the NTN bearing, and the right hand turns the coat to make it rotate to hear if there is any noise. Because most of the production conditions of counterfeit products are lagging behind, complete manual workshops, in the process of production, it is unavoidable to add sand and other impurities, hidden in the bearing body, so it will make a noise when rotating. Because of the domestic antirust technology is not especially home, so the bearing body is easy to leave thick oil trace when the bearing body is antirust treatment, and it is sticky on the hand, and the bearing of foreign original NTN's bearing almost can't see the trace of rust proof oil, but it is a special careful expert that NTN bearing smell has a kind of taste, it must be down Antirust oil, just can't see it.
