In our daily practical use, bearings with the same appearance under the same working conditions have a very different actual life. There are many factors that affect the service life of bearings. Today, let’s briefly introduce the impact of bearing maintenance and rust prevention on the use of bearings?

Bearing maintenance cycle time

How often do you maintain the bearings? The bearing can theoretically be used for 20000-80000 hours. But the specific life depends on the wearer during use, work intensity and later maintenance, etc. Among them, maintenance is an important part of prolonging the service life of bearings

How to maintain the bearing

In order to give full play to the bearing and maintain its due performance for a long time, it is necessary to do regular maintenance (regular inspection). Through appropriate regular inspections, and detect failures early and prevent accidents before they occur. This is very important to increase productivity and save costs. 


People pack the bearings with proper amount of anti-rust oil and paper when they leave the factory. However, for long-term storage, it is advisable to store it on a shelf 30cm above the ground when the humidity in the storage place is below 65% and the temperature is about 20°C. In addition, the storage place should avoid direct sunlight or contact with cold and humid walls.

Bearing cleaning

If you need to clean bearing , when you remove the bearing for inspection, take pictures or video to record the appearance. Confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing. 


a. The cleaning of the bearing has 2 types, rough cleaning and fine cleaning, and a metal grid can be placed on the bottom of the used container. 


b. For rough washing, use a brush in oil to remove grease or adhesions. If you rotate the bearing in oil at this time, be careful that foreign matter may damage the rolling surface. 


c. When fine washing, slowly rotate the bearing in oil, and you must carry out carefully. Commonly used cleaning agents are neutral non-water-containing diesel or kerosene. Sometimes use warm lye as needed. No matter which cleaning agent you use, you must filter it frequently to keep it clean. After cleaning, immediately apply anti-rust oil or anti-rust grease on the bearing. 

Check the bearings

In order to judge whether the removed bearing can be reused, it is necessary to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage, and sealing ring. The higher the importance of the bearing, the more careful inspection you need to do. 


If there are following bearing damages, the bearing must not be reused you must replace the bearing:


  • Fractures and defects of bearing parts
  • The peeling of the rolling surface of the raceway surface.
