Aerospace: Ball Bearing Rod Ends

RBC Aerospace Bearings offers a full line of Mil Spec Standards and many specialty and custom ball bearing rod end anti-friction bearings to the aerospace industry and all major OEM specifications. These double row, self-aligning bearings accommodate the application’s low torque, high load, and misalignment needs. Product conforms to SAE-AS6039, formerly MIL-B-6039.

These double row self-aligning rod ends have inner rings and balls made from thru-hardened 52100 or 440C stainless to accommodate an application’s corrosion resistance needs. The bearings are lubricated 80 to 100% fill in compliance with MIL-PRF-81322, MIL-PRF-23827, and Boeing’s BMS3-33 specifications. Ball bearing rod ends are equipped with PTFE seals bonded to corrosion resistant caps.

The rod end body is selectively heat treated to provide a combination of a fracture tough head, ductile shank, and a carburized raceway to provide high load carrying capacity. External surfaces are plated with cadmium to provide corrosion protection and thread lubricity. The rod end body can be supplied to AISI8620 or RBC’s proprietary AeroCres® corrosion resistant material.
