In general, 33.3% of needle roller bearings are damaged due to fatigue, 33.3% of needle roller bearings are due to poor lubrication, and 33.3% are due to contaminants entering the bearings or improper disposal of equipment.
Fine dust cleans the bearing and the surrounding environment. Fine dust that is invisible to the naked eye is a powerful killer of the bearing. It can increase bearing wear, vibration and noise. When punching forms a strong punch when using the equipment, it is very likely that the needle roller bearing will be damaged or the bearing will be directly struck with a hammer, and the pressure will be transmitted through the rolling body. The impact of non-professional tool installation The use of suitable and accurate equipment can avoid the use of cloth and staple fibers. Needle roller bearings, whether in laboratory tests or in practical use, can clearly see that under the same operating conditions, the appearance of the same needle roller bearings, the actual life is very different.
