The inner and outer rings and rolling elements of rolling bearings should have high hardness and contact fatigue strength, good wear resistance and impact toughness. Generally, they are made of chromium-manganese high-carbon steel (resistant to pitting corrosion). Commonly used materials include GCr15 bearing steel, GCr15SiMn bearing steel, GCr6 bearing steel, GCr9 bearing steel, etc
