EP® Range of Engineered Plastic Materials | GGB
Bearings made from medium or low carbon alloy steel material are typically called “semi-precision” or “commercial grade” bearings. The typical materials are AISI8620 or AISI4320. The inner and outer rings are surface hardened in a heat-treating process call case hardening or carburizing. Bearings made from these materials cannot carry high loads or operate at high speeds and they do not have corrosion resistance. The bearings made …
