1, the bearing life
    Cleanliness of needle roller bearings needle roller bearing life is quite large, the bearings had this special test, the result is the difference even several times. The higher the cleanliness of the bearing, the longer the life of the test showed that: different lubricant cleanliness great influence on the life of ball bearings. Therefore, to improve the cleanliness of the lubricating oil can extend the life of the bearing, in addition, if the lubricant-containing dirt particles is controlled at less than 10um, the bearing life is also a multiple of growth.
    2, the impact of noise and vibration
    Bearing test center test results show that: cleanliness seriously affect the needle bearing vibration levels, especially the vibration of the high frequency band is more significant. Low the high cleanliness bearing vibration velocity, especially in the high frequency band, needle roller bearing grease dust noise tested to prove that the greater the more noise the dust.
    Needle roller bearings cleanliness decreased lubricity, affects not only the lubricating oil film is formed, can also cause deterioration of the grease and accelerate the aging, which affects the degradation of grease lubrication.
    Anti-rust treatment after assembly need to do a good job we can for the entire roller coated with anti-rust paint, this can be a good solution to rust problems, anti-rust paint choice made your selection, and can not use inferior products, or difficult to play a rust; install the entire needle roller bearings, we need to do a good job of preventive measures, Mu Qizhong more susceptible to ignore the problem is to install the best time to wear gloves.
    Assembly bearing to prevent bearing into the foreign body. Needle roller bearings inside the structure is very sophisticated, any foreign entry will bring a lethal threat to the internal structure of needle roller bearings in the assembly when to hold the necessary lubrication, but must be a good seal.
