Bearing test methods at home and abroad, at present. There are four main types:

I. Friction wear test.

Second, the test bench test.

Third, the laboratory (test site) simulation test.

Fourth, the actual operating conditions running test.

Foreign countries on the above several test methods are used, but the application of different purposes, for example, the development of a new product, the first to do the friction wear test. But if the form of friction and wear without much change, only the size of the product, loaded with changes in working conditions, it is only necessary to do the bench, simulation or actual running test can be. Overseas on some key parts of the new product (such as car wheel hub bearings, etc.) test is extremely strict, must be tested by the actual operation, before being allowed to support the use of.
