There are many kinds of ball bearings with good external spherical surface. The sealing structures required by customers are also many, and the requirements of fat filling are different. However, the sealing performance of bearings is strict. In order to improve the product quality of our factory, the sealing structures with different requirements can meet the sealing performance requirements of customers. The problems to be solved are as follows: single lip contact sealing structure without groove in inner ring, and a small amount of grease on the lip How much is the clearance between the outer diameter of the inner ring and the outer diameter of the inner ring? Is the sealing performance test the same as rubber seal ring bearing? How to improve the reliability of bearing sealing performance? The enterprise has a certain scale, standardized management, project industrialization foundation, muffler resistance foundation, and lack of projects with investment value. Project requirements: high added value, products with scientific and technological content, market trend products, achievements protection. It is hoped that through market investigation and feasibility study, the University R & D projects will cooperate with enterprises to produce economic and social benefits.
