First of all, reasonable structure design of both have advanced, there will only be a long United States Timken bearing life. Manufacture of bearings are 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 INA bearings heat treatment and machining processes, often has a more direct relationship with bearing failures. On bearing surface deterioration in recent years studies have shown that, with close ties to INA bearing surface grinding process.
　　INA bearing 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 remains one of the main affecting factors of INA bearing failure. Selection of propriety are still bearing failure analysis of factors that must be taken into account.
　　INA bearing failure analysis of main tasks 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, extending the service period of bearing, avoid unexpected early INA bearing failure.
　　INA bearing seal, at the time of production has been filling the appropriate grease; for bearings sealed were also set in the host device in use to prevent grease leakage.
　　How much this is injected to the INA bearing grease for good questions.
　　Filling grease amount too small, easily give rise to lack of fat or dry friction affect life expectancy. Too much fat can lead to large quantities of grease, which pollute the environment and wasteful. Thus, to INA injected amount of grease in the bearings is to ensure adequate lubrication of the INA under the premise of the less the better.
