What are the effects of cleanliness on the performance of NTN bearings:
The cleanliness of ntn bearing 6201 has a considerable impact on the life of NTN bearings. NTN bearings have carried out special tests for this purpose, and the result is that the difference is several times or even dozens of times. The higher the cleanliness of NTN bearings, the longer the service life. Tests by others have shown that lubricating oils with different cleanliness have a great influence on the service life of ball NTN bearings. Therefore, improving the cleanliness of the lubricating oil can prolong the life of the NTN bearing. In addition, if the lubricating oil contains dirt particles below 10um, the life of the NTN bearing will also increase several times.

Influence on vibration:
ntn bearing 6201 Test Center's test results show that cleanliness seriously affects the vibration level of NTN bearings, especially the high frequency vibration. NTN bearings with high cleanliness have low vibration velocity values, especially in high frequency bands.
Impact on noise:
Tested on the influence of dust in NTN bearing 6201 grease on noise, and proved that the more dust, the greater the noise.
Influence on lubrication performance:
The decrease in the cleanliness of ntn bearing 6201 not only affects the formation of the lubricating oil film, but also causes the deterioration of the grease and accelerates its aging, thereby affecting the lubricating performance of the grease.

Generally speaking, when the bearing emits a uniform and continuous "sizzling" sound, everyone should pay attention. This kind of sound is generated by the rotation of the rolling elements in the inner and outer rings, and contains irregular metal vibrations that have nothing to do with the speed. The general performance is that the amount of grease in the bearing is insufficient and should be supplemented. If the equipment is down for too long, especially in the low temperature conditions in winter, the sound of "sizzling" may sometimes be emitted during the operation of the bearing, which is related to the reduction of the radial clearance of the bearing and the reduction of the penetration of the grease. The bearing clearance should be adjusted appropriately, and new grease with a higher penetration degree should be replaced.

Did you know that poor lubrication of imported bearings is the main factor that can cause premature damage
According to the investigation, poor lubrication is one of the main reasons for the premature damage of imported bearings. The main reasons include: not filling lubricant or lubricating oil in time; not filling lubricant or lubricating oil in place; improper selection of lubricant or lubricating oil; incorrect lubrication method and so on.
Suggestion: Choose the correct lubricant or lubricating oil, and use the correct lubrication filling method.
