At present, the bearing test at home and abroad, there are mainly four categories: friction and wear test, two test bench, the simulation test of the three laboratories (test site), four, the actual working conditions run test.

Abroad These test methods are used, but the application purpose, for example, to develop a new product, first of all need to do friction and wear test. However, if the friction and wear in the form changed much, only the product size, and by changes in the carrier conditions, you just do bench, simulated or actual running test can be. Abroad, some of the key parts of the new product (such as wheel bearings, etc.) assessment is extremely strict, must be allowed to carry out supporting the use of the actual running test. Sweden, SKF bearings, Japan NTN Bearing recent studies bearing simulation, only to replace the bench, simulation or experiment, to shorten product design time and accelerating product development progress, but from the actual operation of the gap. Now, the bearing industry in China has carried out the friction and wear test, one of Luoyang Bearing Research Institute; has been carried out bearing bench, the Luoyang Bearing Research Institute, Shanghai axis Institute, Hangzhou Bearing Test Center and Wafangdian, Harbin, 20 Yu Jiaguo bearing enterprises; can expand the simulation test, Luoyang Bearing Research Institute, Hangzhou bearing test Center and Los axis, Xiang-axis and other enterprises. And to the actual test, only bearing manufacturers in this regard requests to be carried out, such as wheel bearings and the cars of rail passenger wheel bearing host at supporting enterprise. In short, China is not yet widely in carrying out the simulation and the actual running test, should further expand the host range or scope of the actual working conditions, early on the agenda for the simulation test for adequate soft, hardware preparation
