Heat-treating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth. Descaling: This step removes the residues and by-products from the heat-treating process. Hard Grinding: Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as close as ±.0001".

How are bearing balls made? Engineering360

Jul 31, 2019  Grinding. Now that the balls are hardened and relatively round, they are nearing the end of the manufacturing process. The next step is to grind the balls to size them and improve roundness geometry. The process is similar to the soft grinding process used earlier — the balls are rolled between a steel plate and a fine-grit grinding wheel.
