    Wheel bearing race composition?

    Anyone know what metals are in the races of NDH or Timmken wheel bearings such as those used in Corvettes?

    The standard industry classification for the steel in these bearings is 52100, which means that it has one percent chromium and one percent carbon (called alloys when added to the basic steel). This steel can be made very hard and tough by heat treating. Where rusting might be a problem, bearings are made from 440C stainless steel
