Tapered bore sealed bearings
When installing the self-aligning sealed ball bearing to the adapter sleeve, please use the H3..E series adapter sleeve. These adapter sleeves are equipped with KMFE lock nuts, which have a groove on the side to prevent damage to the seal.
Bearings with extended inner ring
The self-aligning bearing with an extended inner ring is axially fixed on the shaft by positioning pins or screws. When two self-aligning ball bearings with extended inner rings are used to support a shaft at the same time, the two bearings should be correctly positioned so that the grooved sides of the inner rings are opposite or opposite to each other. Otherwise the shaft can only be positioned axially in one direction.

There are three ways to reduce vibration:
1. Remove critical excitation vibration from the application;
2. Restrain the critical excitation vibration between the excitation component and the resonance component;
3. Change the stiffness of the structure, thereby changing the critical frequency.
It is of great significance to study the formation of NTN bearing damage and noise generation
In the process of using NTN bearings, due to its own quality and external conditions, its load capacity, rotation accuracy and friction reduction performance will change. When the performance index of the bearing is lower than the use requirements and cannot work normally, it is called If the bearing is damaged or fails, once the bearing is damaged or other unexpected conditions, various abnormal phenomena such as the machine and equipment stopping and the function being damaged will appear.
Therefore, it is necessary to investigate and deal with the causes in the short term and take corresponding measures. Of course, the damage of NTN bearings is much more complicated than the damage of general mechanical parts. The characteristics of rolling bearing damage are many manifestations, and the reasons are complex. Most of the internal factors of design and manufacturing are caused by improper use, for example: improper installation, poor lubrication, poor sealing and other external factors.
It is of great significance to study the formation and causes of NTN bearing damage. On the one hand, it can improve the use method, use the bearing correctly, give full play to the bearing's due efficiency, and on the other hand, help to develop new products with better performance. In addition to the precautions, installation methods, and operation monitoring of rolling bearings, this article focuses on the form and causes of bearing damage and the countermeasures to be taken.
