How are Ball Bearing Made?

The balls may then be soft ground by some manufacturers. Because this material has not yet hardened, it is called “soft.” This procedure is similar to flashing, but instead of a metal plate, an abrasive grinding stone is used. Assembling To harden and strengthen the balls, they’ve had the excess material removed and are now relatively round. After being heated to about 1,500 degrees Fahrenheit, the balls are cooled in an oil bath. This time the temperature is reduced significantly—a temperature of about 325 degrees Fahrenheit, resulting in a wholly hardened ball. Descaling The balls are discolored and covered in oxide deposits after heat treating. Descaling is used to remove these impurities from the balls. The buildup on the balls can be removed chemically, usually with an acidic compound, through descaling. Grinding The manufacturing process is winding down now that the balls have hardened and are reasonably round. The next step is to size and improve the roundness geometry of the balls by grinding them. The balls are rolled between a steel plate and a fine-grit grinding wheel, similar to the soft grinding process from before. Lapping Lapping the balls is the final step in the manufacturing process. As a super-finishing process, lapping helps the balls achieve the required tight tolerances by improving the surface finish or geometry and removing microscopic material. Between two hardened steel plates, one fixed and the other rotating at a low speed, the balls are rolled. The balls have been polished to a mirror-like finish and are now perfectly rounded. Sizing and cleaning Afterward, they are rinsed to remove any remaining residue from the manufacturing process. As a final step, the polished balls are examined for flaws and measured to ensure proper size. Even though the balls all have the same nominal diameter, there are still a few minor differences in the diameters of the balls. The ball grade determines the bearing’s geometric tolerances—the tighter the patience, the lower the grade number. The degree of sphericity and diameter variation in the balls is directly proportional to the grade number. Despite the tight tolerances, the divergence between balls is shallow. CONCLUSION
