在购买青岛NSK轴承的时候，大家都想要买到质量好的产品，但有些时候却受到了各种因素的影响，所以直接导致了今后购买受到制约。人们在购买的过程中，如何来做好对质量好坏的分辨？提前做好正确的认识，很多的事情对我们来说会有更多的保障，今后在选择的时候，也有了适合的判断依据。
In the purchase of NSK bearings, we all want to buy good quality products, but sometimes by a variety of factors, so directly led to the purchase of restrictions in the future. In the process of buying, how can we distinguish between quality and good quality? Do a good job in advance of the correct understanding, a lot of things for us will have more protection, in the future when the choice, there is also a suitable basis for judgment.
一方面，NSK轴承采用的材料硬度比较高，冲击过大就容易出现裂纹的情况。尤其在很多的情况之下，一旦受到了比较大的震动冲击，那么出现裂纹也是必然的现象，所以必须要在这些方面都有所认识。日常在使用的过程中，避免一些较大的冲击。
On the one hand, NSK bearings used material hardness is relatively high, too large impact is prone to cracks. Especially in many cases, once subjected to a relatively large shock, then cracks are inevitable phenomenon, so we must have some understanding in these aspects. In the daily use of the process, avoid some big impact.
当然，有些人在对NSK轴承进行拆卸安装的过程中，他们可能操作的方法不当，过分地进行敲击，用力不均匀，这样很容易出现裂纹。日常在使用的过程中，真正的找到比较正确的方法，然后再进行拆卸，这样才能够有所保护，避免出现这样的问题，从而带来了一定的麻烦。
Of course, some people in the process of disassembly and installation of NSK bearings, they may operate improperly, excessive knocking, uneven force, so easy to crack. In the daily use of the process, really find a more correct method, and then disassemble, so as to be able to protect, avoid such problems, thus bringing a certain amount of trouble.
外在的用力不均或者是相对来说比较大的震动冲击，都有可能引起NSK轴承出现裂纹。有些时候，可能也不是因为外力的原因，而是因为在生产的过程中，他们使用质量不是特别好的材料，还有可能是因为内部的一些缺陷。在购买的过程中，我们都要认真的进行识别好分辨，真正的去买到质量更好的轴承，这样可以减少今后的一些麻烦。
Non-uniform external force or relatively large vibration impact may cause NSK bearing cracks. Sometimes, it may not be because of external forces, but because in the process of production, they use materials that are not particularly good in quality, and it may be because of internal defects. In the process of purchasing, we must conscientiously identify and distinguish, to really buy better quality bearings, which can reduce some trouble in the future.
