  • Mfr. P/N & Title: MKP20AFS428 RBC SAE-AS7949 MKP A Series Airframe Radial Ball Bearing

RBC® BEARINGS MKP/MKP-A...

The RBC® BEARINGS offers a full line of airframe control ball bearings to the aerospace industry  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.

RBC® BEARINGS 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® BEARINGS  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.

The RBC® BEARINGS MKP/MKP-A SAE-AS7949 Precision Series airframe control bearings are single row, heavy duty (MKP) or medium duty (MKP-A) radial ball bearings with PTFE seals and CRES sealcaps. MKP Series bearings conform with MS27640-R specifications while those of MKP-A Series with MS27641-R. External surfaces (except bore, caps, and seals) are cadmium plated. They come prelubricated for life and are also offered with CRES 440C material and/or zinc nickel plating per OEM specifications. For additional information please refer to the supplied documentation.
