Ring and Rolling Element Materials
Rings and rolling elements are usually made of high carbon chromium bearing steel. Most bearings use CCr15, and CCr15SiMn with good hardenability is used for bearing rings with larger cross-sections and rolling elements with larger diameters. High-carbon chromium bearing steel is an overall hardened steel, and its surface and core can be hardened, so it is the best material for rolling bearings.
