The heat treatment process of high-temperature bearing rings and rolling elements ensures that the bearings are dimensionally stable within 150 degrees. For higher operating temperatures, special heat treatments are required. If IKO bearings are used in corrosive environments, the bearing steel needs to be corrosive. Standard bearings made of stainless steel have the prefix "S" and the suffix "W203B" added to the code name. The main dimensions and load-carrying capacities of this type of bearing are the same as those of solidly quenched steel bearings. In order to maintain its corrosion resistance, its surface cannot be damaged during installation and use.
