I have been working in the bearing industry for more than 30 years, familiar with the application of various bearings, and have my ideas on the use of materials and structure optimization of bearings, and can propose optimization solutions in the bearing production process, in the hope of improving production efficiency and bearing life. In 2015, I set up the first bearing analysis museum in China, collecting many failed bearings, analyzing and collecting the causes of bearing failure, and providing valuable technical support in bearing application and bearing optimization.
