The development of domestic bearing life testing machine has gone through more than 40 years. It basically has skilled R & D technology, rich testing experience and accumulated a large number of test data. Although some research results have been obtained, there are too many and complex factors affecting bearing life, and the data processing of bearing life experiment still needs to be further improved. Now it is necessary to establish a database on Bearing fatigue mechanism research, failure factor analysis, material smelting and processing technology, test data analysis and other related technologies, and put forward the recommended values of various correction coefficients for domestic bearing life calculation as soon as possible, so as to be suitable for all kinds of bearing service information with rapid innovation.
