1, the impact on the life expectancy of bearings

Impact of cleanliness of FAG bearings needle roller bearing life considerably, bearing who conducted a special test, is the difference between the results for several or even dozens of times more than double. Bearing cleaning more, longer life and other people′s experiments show that different cleanliness of the lubricant to the ball bearing life considerably. Therefore, improve the cleanliness of the lubricant can extend the life of the bearing, in addition, lubricant with dirt particles control 10um, bearing life into several times growth.

2, the effect of noise and vibration

Bearing Test Center test results showed that cleanliness seriously affect FAG bearing vibration levels, especially high-frequency vibrations more visible. Clean bearing vibration velocity values for high low, especially in the high frequency band, the needle roller bearing grease dust effects on noise test, prove that dust as much noise as possible.

3, effects on lubrication performance of FAG bearings drop in cleanliness, affect not only the lubricant film formation, also cause spoilage and accelerate their ageing of grease, thus affecting the grease lubrication performance.

Assembly zhihou needs do rust processing, we can for whole asked roller James Shang a layer paint, such on can is good to solution rust problem, paint of select needs do select, cannot using inferior products, or hard up to rust of processing; in installed whole needle roller bearings of when we needs do prevention sexual measures, MOU qizhong comparison easy was ignored of problem is installed of when best with Shang gloves.

Assembled on bearings, try to prevent the bearings from entering foreign objects. Because the needle very sophisticated internal structure, any foreign bodies entering the FAG bearing structure posed a deadly threat, to maintain the necessary lubrication at assembly time, and it is necessary to make a good seal.
