How to ensure the service life of the bearing?

In order to make the bearing fully play and maintain its due performance for a long time, it is necessary to do a good job in regular maintenance (regular inspection). It is very important to improve productivity and economy to find faults early and prevent accidents before they happen through appropriate periodic inspections. Storage Bearings are coated with an appropriate amount of anti-rust oil and packaged with anti-rust paper before leaving the factory. As long as the package is not damaged, the quality of the bearing will be guaranteed. However, for long-term storage, it is advisable to store it on a shelf 30cm above the ground under the conditions of humidity below 65% and temperature around 20°C. In addition, the storage place should avoid direct sunlight or contact with cold walls. Cleaning When the bearing is disassembled for inspection, first make a record of its appearance by photography or other methods. Also, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.

The cleanliness of the bearing has a great influence on the life of the bearing. The higher the cleanliness of the bearing, the longer the service life. The lubricating oil with different cleanliness has a great influence on the life of the ball bearing. Therefore, improving the cleanliness of the lubricating oil can prolong the life of the bearing. In addition, if the dirt particles in the lubricating oil are controlled below 10um, the life of the bearing will also increase several times.

(1) Impact on vibration: Cleanliness seriously affects the vibration level of the bearing, especially the vibration in the high frequency band is more significant. Bearings with high cleanliness have low vibration velocity values, especially in high frequency bands.

(2) Effect on noise: The effect of dust in bearing grease on noise has been tested, and it is proved that the more dust there is, the greater the noise will be.

(3) Influence on lubrication performance: The decline of bearing cleanliness not only affects the formation of lubricating oil film, but also causes the deterioration of lubricating grease and accelerates its aging, thus affecting the lubricating performance of lubricating grease.
