There is no problem with the selection of NSK bearings. The bearings will run smoothly in the future. The lubrication method and lubricant are selected correctly. Normally, the bearings can work normally for a long time. There are many factors that cause bearing damage, such as man-made factors, environmental factors, service conditions, and bearing damage caused by comprehensive reasons. The following are the main reasons for consideration, which are also the most common reasons for bearing companies:

1.Poor lubrication: According to investigations, poor lubrication is one of the main causes of premature bearing damage. The main reasons include: not filling lubricant or lubricant in time; lubricant or lubricant not filling in place; improper selection of lubricant or lubricant; incorrect lubrication method, etc. Recommendation: Choose the correct lubricant or lubricating oil, and use the correct lubrication filling method.

2.Improper installation: using brute force during installation, directly hitting the bearing with a hammer, will cause the greatest damage to the bearing; it is the main cause of deformation. The installation is not in place, the installation is deviation or the bearing is not installed, resulting in too small bearing clearance. The inner and outer rings are not at the same center of rotation, resulting in different concentricity. Suggestion: Choose appropriate or professional bearing installation tools, and use special instruments to test after installation.
