Factors affecting bearing life

There are many factors may affecting bearing working life, here are some main factors need paying special attention to.

1,the coordination of bearing and bearing seat hole

The biggest influence factor of the running accuracy and the length of the life of bearings comes from the matching accuracy of the bearing seat holes.Bearing seat holes should meet the precise size requirements of bearings, and batch size should have uniformity, which is difficult to achieve in mechanical processing, the use of new processing technology processing is the urgent need of bearing users. In this case, Powerlong design the drawn cup needle roller bearing with groove or knurling outer ring to better coordinate with the bearing hole.

2,the cleanliness of bearing working environment

The cleanliness of bearings has a great influence on the life of needle roller bearings. Bearings have carried out special tests for this purpose, and the results are that the difference is several times or even tens of times more.The higher the cleanliness of bearings, the longer the life of bearings and other tests show that different cleanliness of lubricating oil has a great impact on the life of ball bearings.Therefore, improving the cleanliness of lubricating oil can prolong the life of bearings. In addition, if the lubricating oil containing dirt particles is controlled below 10um, the life of bearings will also increase by several times.

3,lubrication condition

Proper lubrication can ensure the performance of bearings and prolong their service life. The purpose of lubrication of rolling bearings is to reduce internal friction and friction loss of bearings and prevent burning and sticking.Powerlong add different grease and oil according to the needle roller bearing according to clients' actual condition.

4,working temperature

High temperature often indicates that the bearing is in an abnormal situation.High temperature is also harmful to bearing lubricants.Sometimes bearing overheating can be attributed to bearing lubricants.If the temperature exceeds 125℃ for a long time, the bearing life will be reduced.Causes of high temperature bearings include: insufficient lubrication or excessive lubrication, lubricants.It contains impurities, excessive load, bearing ring damage, insufficient clearance, and high friction caused by oil seal, etc.
