RBC Aerospace Bearings offers standard and many specialty and custom designed radial ball bearings to the aerospace industry and all major OEMs. RBC’s radial ball bearings are offered in Conrad-type, full compliment, sealed and unsealed designs. These bearings are offered in ABEC 1 through ABEC 7 precision grades, pre-loaded, corrosion protected, grease-lubricated, and are available with numerous separator, ball, shield, seal, and lubrication options. Bore sizes range from 3/16 inch to 6 inches. Standard radial ball bearings have SAE 52100 steel rings and balls. RBC radial ball bearings can be manufactured from other specialty bearing steels to provide corrosion resistance, high temperature capability, alternative load capacity, or chemical compatibility. RBC has manufactured radial ball bearings from CRES 440C to provide corrosion resistance. As an alternative to CRES rings, the entire surface of the rings can be plated with thin dense chrome (TDC). This plating, which meets AMS 2438, achieves a molecular bond that will not flake, peel, or separate from the base material. RBC offers “T8” rings for superior corrosion resistance and M50, BG42 rings for high temperature applications. Some special ball materials include CRES 440C, silicon nitride, and M50 steel.
