GCR15 bearing roller has very high requirements for the smelting quality of bearing steel, and it is necessary to strictly control the content and distribution of sulfur, phosphorus and non-metallic inclusions, because the content and distribution of non-metallic inclusions have a great impact on the life of bearing steel. The basic quality requirements for bearing steel are purity and uniform organization. Purity means that there are fewer impurity elements and non-metallic impurities, and the uniform structure means that the carbides in the steel should be fine and the distribution should be even. The higher the amount of inclusions, the shorter the life span. In order to improve the quality of smelting, electric furnace smelting and electroslag remelting have been used recently, and new processes such as vacuum smelting and vacuum consumable refining can also be used to improve the quality of bearing steel.
Use of GCR15 bearing roller

In addition to making balls and bearing rings, GCR15 bearing roller is sometimes used to make tools, such as dies and measuring tools.
GCR15 bearing roller,Spherical roller bearings consist of an inner ring with two raceways inclined at an angle to the bearing axis, an outer ring with a common spherical raceway, spherical rollers, cages and, in certain designs, also internal guide rings or center rings . The bearings can also be sealed.
Most spherical roller bearings are designed with two rows of rollers, allowing them to take very heavy radial loads and heavy axial loads. There are also designs with one row of rollers, suitable for lower radial loads and virtually no axial load. These are also called "barrel roller bearings" or "Tonnenlager" and are typically available in the 202- and 203-series.
