RBC Aerospace Bearings offers a full line of Mil Spec standards and many specialty and custom spherical plain bearings to the aerospace industry and all major OEM specifications. Both metal-to-metal and self-lubricating bearings are available. Configurations include swaged construction, load leader slot, split ball and high misalignment designs, with high temperature and light weight titanium and aluminum series offered. Sealed versions are also available.

Various materials are used in RBC swaged spherical bearings including races made from 17-4PH, 15-5PH, aluminum-bronze, AISI303, Inconel® -718, aluminum, and titanium, and spherical plain balls made from 440C, 52100 chrome plated, 13-8PHMo, Stellite®, Beryllium-Copper, aluminum and titanium. Race and ball surfaces may also be provided with a dry film lubricant for high temperature applications or various coatings to enhance corrosion resistance and reduce wear.
