Chrome Steel 52100 Grade 100 ball bearings are manufactured from a high-carbon, chromium-containing steel alloy known for its exceptional hardness and wear resistance. These Grade 100 bearings are engineered with a high degree of precision, maintaining a sphere tolerance within 0.0001 inches to ensure smooth operation in demanding environments. Their excellent fatigue strength makes them an ideal choice for high-load applications, including automotive assemblies and heavy industrial machinery. The material's through-hardened properties provide uniform durability throughout the entire ball, preventing surface deformation under extreme pressure. With a finely polished finish, these bearings minimize friction and vibration, significantly extending the service life of rotating components.
