Airframe Control Ball Bearings
RBC offers a full line of airframe control ball and roller anti-friction bearings to the aerospace industry. RBC airframe control bearings conform to SAE-AS7949 (formerly MIL-B-7949) and all major OEM specifications. These bearings are of lightweight design, corrosion protected, 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 and seals cadmium plated for corrosion protection. For improved corrosion protection, RBC supplies bearings made of hardened stainless steel alloy, AISI 440C. This alloy may, in addition, be passivated or cadmium plated for enhanced corrosion protection. Additionally, RBC offers airframe control bearings zinc nickel plated to the above base metals, providing an alternative to cad plate (ASM2417).
