RBC offers a full line of airframe control ball bearings to our industrial customers. RBC airframe control ball bearings conform to SAE-AS7949 (formerly MIL-B-7949) and many major OEM specifications. These bearings are of lightweight design, corrosion-resistant, grease-lubricated, and typically sealed. Airframe control bearing rings and balls are made of hardened bearing alloy, AISI 52100, with all exposed surfaces, except bearing bore, caps and seals, plated for corrosion protection. For improved corrosion protection, RBC supplies bearings made of hardened stainless steel alloy, AISI 440C. This alloy may be passivated or plated with cadmium or zinc nickel for enhanced corrosion protection. RBC supplies airframe control bearings in both “Standard” and “Precision” series. The prefix “M” in a bearing number indicates that it is of a precision series. Although designed and manufactured under demanding quality control requirements for airborne systems, these bearings have been successfully used in many industrial applications, where oscillatory movement, high loads, or corrosive environments are prevalent
