The cleanliness of deep groove ball bearings has great influence on the service performance and life of bearings. It is an important quality index of low noise, high reliability, long life and precision bearings.
Effect of cleanliness on service performance of bearings
(1) The influence of cleanliness on bearing life
Specialized tests have been carried out on Mingwei bearings. It has been proved that the clearance of bearings has a considerable effect on the life of bearings, and the difference can be several times or even more than 30 times. In addition, if the cleanliness of lubricating oil is high and the contamination particles are controlled below 10pm, the bearing life will also increase several times.
(2) The influence of cleanliness on bearing vibration and noise
The special study on the influence of cleanliness on vibration and noise has been carried out by China Bearing Test and Research Center. The results show that cleanliness seriously affects the vibration level of bearings, especially in high frequency band.
(3) The influence of cleanliness on lubrication performance of bearings
The deterioration of bearing cleanliness will not only affect the formation of lubricant film, but also cause deterioration and accelerated aging of lubricant, thus affecting the lubrication performance.
In order to ensure a clean production environment for bearings, Mingwei bearings have established a dust-free production workshop, completely saying goodbye to the previous situation of dust and oil stained workshop, and preparing for the production of high-quality and clean bearings.
