In general, 33.3% of needle roller bearings were damaged due to fatigue damage, 33.3% of needle roller bearings were due to poor lubrication, and 33.3% were due to improper entry of contaminants into bearings or equipment.
Dust clean bearings and the surrounding environment, the tiny dust that is invisible to the naked eye is a powerful killer of the bearing, which can increase the wear, vibration and noise of the bearing. When punching forms a strong press when using the equipment, it is highly likely that the needle bearing will be damaged or the hammer will be directly struck by the hammer, and the pressure will be transmitted through the roll. The impact of non-professional tool installations is based on the use of appropriate and accurate equipment, and the use of cloth and staple fibers can be avoided. Needle bearings can be clearly seen in the laboratory test or in actual operation. The needle bearing with the same appearance under the same working conditions has a very different life span.
