Aerospace  - Airframe Control Bearings

RBC Aerospace Bearings offers a full line of Mil-Spec standard and many specialty and custom designed plain rod ends to the aerospace industry and all major OEMs.  These bearing assemblies incorporate a spherical bearing swaged into the rod end body or a loader slot design.  Plain rod end bearings are available in high misalignment, high temperature, and light weight titanium series with external or internal threads, optional keyways, and slots.

The rod end bodies are designed to provide high strength and ductility.  Common materials for the body are: 4340 cadmium plated, 17-4PH, 15-5PH, PH13-8Mo, Titanium, Inconel® 718, Aluminum and other materials.   The inserts provide the rod end with high misalignment and load carrying capability.  The insert bearings may be of 17-4PH, 440C, 52100 chrome plated Inconel® 718, Cobalt, Aluminum, Beryllium-Copper, or PH13Mo.  The loader slot bearing has the additional ability to remove and replace the spherical ball.  (Inconel® is a registered trademark of the INCO family of companies)    

RBC manufacturers a number of self-lubricating liner materials that are qualified to AS81935 (formerly MIL-B-81935).  In addition, over 60 other self-lubricating materials are available for specific characteristics; such as high temperature for turbine engine applications, or for airframe, helicopter, and landing gear applications.

RBC plain rod end bearings have been qualified to stringent SAE, military, AECMA, and customer design and performance standards in RBC test laboratories.  For information on special plain rod end bearings or for information on the many standard series of plain rod end bearings available from RBC, please consult RBC Customer Service at 866.RBC.AERO (866.722.2376).
