Effect on maintenance-free bearing life:

The cleanliness of maintenance-free bearings has a great influence on the life of the bearings. Professional tests have been carried out on maintenance-free bearings, and the result is that the difference is many times or even dozens of times. The higher the cleanliness of maintenance-free bearings, the longer the life of the test shows: different cleanliness of grease has a great impact on the life of ball bearings. Therefore, improving the cleanliness of the grease can increase the life of the bearing. In addition, if the grease contains waste particles below 10um, the life of the maintenance-free bearing will also be multiplied.

免维护系列Effect on Vibration:

The test results of the Bearing Test Management Center show that the degree of 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 high frequency bands.

Impact on noise:

The influence of floating dust in bearing lubricating grease on noise was tested, 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 continues to cause mildew and accelerated embrittlement of lubricating grease, which in turn affects the reduction of wetting performance of lubricating grease.
