NTN Bearing determine the length of life of the internal and external factors
Posted by Andycan on August 31st, 2016
NTN bearing factors that determine the length of life are many, but can be broadly divided into two types, one is internal (factors bearing itself), the other is external bearing.
NTN Bearing factors mainly including structural design, quality of materials and manufacturing processes, such as three factors.
NTN Bearing Manufacturing generally through forging, heat treatment, turning, grinding and assembly of multi-channel processing. However, the reasonableness of the processing technology, advanced, stability will also affect the bearing life. Which affect the quality of products bearing the heat treatment and grinding processes generally have a more direct relationship with the failure of the bearing.
In recent years, research on the bearing housing surface metamorphic layer showed that the grinding process is closely related to the bearing surface quality.
Metallurgical quality of NTN bearing material was the main factor in the impact of the early Rolling failure. As metallurgical techniques (such as bearing steel vacuum degassing, etc.) progress, raw material quality is improved. Raw material quality factors in bearing failure analysis, the proportion has decreased significantly, but it is still one of the main factors bearing failure. The selection is still appropriate factors bearing failure analysis must be considered.
NTN ball bearing external factors mainly include installation and adjustment, use and maintenance, repair and other maintenance meets the technical requirements.
According to NTN bearing installation, use, maintenance, maintenance of the technical requirements for operation of the bearings to withstand load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find reasons to adjust it Back to normal.
Bearing installation conditions is one of the primary factors in the use of factors, bearing caused by improper installation package bearing force status changes between the parts, bearings operate under abnormal state is the key to early termination of life.
