For deep groove ball bearings used in different application scenarios, we can provide various materials such as GCr15, 9Gr18 9Gr18Mo, 0Cr18Ni9, and 06Cr17Ni12Mo2. Meanwhile, we adopt the production technology to re-treat the surface of the bearing material, which improves the contact area between the rolling elements and the raceway, enhances the load-carry capacity, and better deals with impacts, temperature rise, and dusty environments, thus meeting the demands of long service life and high performance of the bearings
