H B C Bearings - Bearing Materials
H B C Bearings uses highly pure vacuum-degassed bearing steel containing a minimum of oxygen, nitrogen and hydrogen compound impurities commonly know as 52/100. This high carbon chromium steel is used for the bearing rings and rolling elements. The rolling fatigue life of bearings has been dramatically improved using these materials combined with the appropriate heat treatment.
Special purpose bearings require high temperature bearing steel, which has superior heat resistance. Stainless steel having good corrosion resistance may be used. This steel is commonly known as 440C.
H B C Bearings uses low carbon steels for the pressed cages. Depending on the application, brass, stainless steel, nylon and synthetic resin may also be used.
