Needle roller bearing

 

In general, 33.3% of needle roller bearing damage is due to fatigue damage, 33.3% of needle roller bearings are due to poor lubrication, and 33.3% are due to pollutants entering the bearing or improper disposal of equipment. [1]

 

Fine dust clean bearings and the surrounding environment, invisible to the naked eye fine dust is a powerful killer of bearings, it can increase bearing wear, vibration and noise. Stamping in the use of equipment to form a strong stamping, it is likely to lead to needle bearing damage or the use of hammer directly hit the bearing, through the tumbling body transfer pressure, etc. Using suitable, accurate equipment, you can avoid the use of cloth and staple fibers and the like. Whether needle roller bearings are tested in the laboratory or in practical application, it can be obviously seen that needle roller bearings with the same appearance under the same operating conditions have great differences in their actual life
