Effect on maintenance-free bearing life


The cleanliness of maintenance-free bearings has a great impact on the life of the bearings. Professional tests have been carried out on maintenance-free bearings, and the results are that the difference is many times or even dozens of times. The higher the cleanliness of maintenance-free bearings, the longer their service life. Experiments show that greases with different cleanliness have a great impact on the service life of ball bearings. Therefore, improving the cleanliness of the grease can extend the life of the bearing. In addition, if the waste particles contained in the grease are controlled below 10um, the life of the maintenance-free bearing will also be increased many times.


Effect on vibration

The test results of the Bearing Test Management Center show that cleanliness seriously affects the vibration level of the bearing, especially the vibration in the high-frequency band is more obvious. Bearings with high cleanliness have low vibration rate values, especially in the high frequency band.


Impact on noise

Tests were conducted on the impact of floating dust in bearing lubricating grease on noise, and it was confirmed that the more floating dust, the greater the noise.


Effect on wetting properties

The reduction of bearing cleanliness not only affects the formation of grease film, but also causes the mildew of the grease and accelerates its embrittlement, which in turn affects the wetting performance of the grease.
