We use SUS630 stainless steel, which has excellent corrosion resistance and hardens through heat treatment.
This is a high corrosion-resistant bearing that achieves high corrosion resistance and high hardness, enabling a long lifespan in all corrosive environments. "Features" 1. It has superior corrosion resistance compared to SUS440C stainless steel bearings. 2. It can be used in larger load and faster rotational ranges than SUS304 stainless steel bearings. 3. It comes standard with fluorine-based chemical-resistant and heat-resistant grease, making it suitable for use in high temperatures and corrosive environments. 4. It is a hybrid type that uses silicon nitride ceramic balls (Si₃N₄).
