Research on formation and NTN bearing damage is of great importance for the noise - bearing knowledge

In the process of using the NTN bearing, due to the quality of itself and external conditions, the cause of its bearing capacity, rotational accuracy and antifriction performance etc. Will change, when the performance of the bearing is lower than the use requirement and cannot work normally, is called a bearing damage or failure, bearing in the event of damage, such as accident happens, there will be stalling its machines, equipment, functional damage and other anomalies. So you need to investigate causes in a short time, and take corresponding measures, of course, NTN bearing damage situation of the damage is much more complex than general machinery parts, the characteristics of the rolling bearing damage is the number of forms, reasons, bearing damage in addition to bearing design and manufacture of the inner factors, mostly due to improper use, such as: selection of suitable ( See the customer information) , bearing design is unreasonable, improper installation, poor lubrication, sealing is not good and so on caused by external factors. Study the formation and reasons of NTN bearing damage has the vital significance, on the one hand can improve the using method, proper use of bearings, bearing should have adequately, on the other hand help develop better performance of new products. In this article, in addition to the narrative in the rolling bearing use note, method of installation, operation and supervision thereof, also introduces the forms and causes of damage and the countermeasures should be taken. Bearing noise is an issue many brand bearings will produce, but the reason is the same, just follow heng nuo tong NTN import bearings distributors to see what are the causes of NTN bearing noise: 1. NTN bearing in sand or impurities such as carbon, acids or paint and other dirt, 2. NTN bearing in mixed with water. Corrosion effect; 3. NTN bearing clearance is too small ( Choose the wrong) 4. Lubricating oil or grease varieties selected wrong; Oil or grease seal leakage) 5. Lubrication lack ( The oil level is too low. Or a hole distortion is not straight) 6. NTN bearing is hole clip flat ( A hole roundness is not good. 7. NTN bearing seat bottom of mat iron uneven ( Lead to a hole deformation even NTN bearing cracks) 8. NTN bearing hole with sundry ( Residues have a chip. 9. Seal eccentric ( Touching the adjacent components and friction)
