Factors contributing to shortened service life of INA self-aligning ball bearings have?

Factors influencing the self-aligning ball bearing service life may be many, using factors and internal factors can come from further clarification.
Use factors mainly refer to installation and adjustment, maintenance, maintenance, repairs and other compliance with technical requirements. Based on self-aligning ball bearings technical requirements for the installation, use, maintenance, maintenance, INA bearings in the operation to take the load, speed, temperature, vibration, noise monitoring and checks and lubrication conditions, abnormal findings immediately find the cause to adjust, bring it back to normal. Installation conditions is one of the leading factors in the use factor, bearing package is often caused by installing is not the right state of change between the various parts of the bearing, bearing under abnormal operation and early life
Internal factors mainly refer to structural design, manufacturing processes and quality of materials, three major factors in determining bearing quality.
Self-aligning ball bearings metallurgical quality of the materials used to be the main factors affecting the early failure of rolling bearings. As metallurgical technology (such as bearings, such as vacuum degassing of steel) of the progress, raw materials quality has been improved. Raw materials quality factors of INA bearing failure analysis of market share has declined significantly, but it is still one of the main factors bearing failure. Selection of propriety are still bearing failure analysis of factors that must be taken into account.
INA bearing manufacturing generally after forging, heat treatment, machining, grinding and assembling multi-channel processes. Rationality, advanced processing technology, will also affect the stability of the bearing life. Which affect the quality of finished product bearing heat treatment and machining processes, often has a more direct relationship with bearing failures. On bearing surface modification layer of work in recent years studies have shown that close to grinding and surface quality of bearing.
Main tasks of the self-aligning ball bearing service life analysis, is based on the large amount of background material, analysis of data and failure mode, identify the main factors causing bearing failure, so targeted for improvement measures, extend the service of INA bearing, avoid unexpected early bearing failure.
