NTN one-way thrust ball bearing failure emergency special methods

On one-way thrust ball bearing fracture failure reason, there are many many people don't know what should be paid attention to in the process of doing. To avoid an accident. To avoid these problems thoroughly, that is impossible. We now to tell you about to find the root of these problems, from the roots to prevent the occurrence of these problems. NTN bearing failure of the main reason is that defects and overload two factors. When the loads more than material strength limit fracture caused by parts called overload fracture. Overload reason mainly is the main engine failure or improper installation. Composite self-lubricating bearings on the installation of metal ring, composite bearings, one-way thrust ball bearing, bearing arrangement in a proper size of the hole, and embedded molybdenum disulfide, graphite and the orderly development of the basic metal friction NTN bearing surface structure, area is 5 - solid lubricant friction 65%. For normal operation of the 280 ℃ high temperature solid self-lubricating block. However, because of its low mechanical strength, bearing capacity is weak, prone to distortion, it in metal cans, can inhibit the shortcoming of this hole, forming a metal part of the load, self-lubricating, lubricant. Continuous wear will cause a one-way thrust ball bearing parts damaged gradually, and ultimately result in the loss bearing dimensional accuracy and other related issues. Wear may affect the shape change, the increase of fit clearance and working surface morphology change, may affect the lubricant or make its pollution to a certain degree of lubrication function is lost, so that loss of bearing rotating accuracy and will not operate properly. Wear failure is one of the common failure modes of all kinds of NTN bearing, according to the wear and tear is usually divided into one of the most common form of abrasive wear and adhesive wear. In the face of the bearing failure fracture, we tend to forget for one reason, he is the most basic point, that is the raw material, NTN bearing. If there is something wrong with the raw material, is in the process of installation and use in cautious is one-way thrust ball bearing damage, fracture can't even use. So, it is very important to the inspection of raw materials.
