Roller Bearing Company, Inc.

RBC Aerospace Bearings offers a full line of standard and many specialty and custom designed thin section ball bearings to the aerospace industry and all major OEMs. RBC’s thin section ball bearings are offered in radial contact, angular contact, 4-point contact and sealed radial contact designs. These bearings are offered in ABEC 1 through ABEC7 precision grades, pre-loaded, corrosion protected, grease-lubricated, and are available with numerous separator, ball, shield, seal, and lubrication options. Standard thin section ball bearings have SAE 52100 steel rings and balls. RBC thin section ball bearings can be manufactured from other specialty bearing steels to provide corrosion resistance, high temperature capability, alternative load capacity, or chemical compatibility. RBC has manufactured thin section ball bearings from SAE 440C stainless steel to provide corrosion resistance. As an alternative to CRES rings, the entire surface of the rings can be plated with nodular thin dense chrome (TDC). This plating, which meets AMS 2438, achieves a molecular bond that will not flake, peel, or separate from the base material. Special RBC thin section ball bearings have been manufactured from aluminum, 300 series stainless steel, 17-4PH and other metals. Some special ball materials include CRES 440C, 300 series stainless steel, silicon nitride, and M50 steel. RBC supplies thin section ball bearings with many different lubricants depending on the application requirements. Greases that are designed specifically for high speed, low torque, water resistance, high temperature, and oscillatory motion can be provided. Additional lubricants, such as dry film, are suitable for use in vacuums and space applications. Radial play (diametral clearance) can be adjusted for mounting fits or temperature changes. Pre-loads can be ground into the bearings to increase or decrease loads to meet particular application requirements. In addition, mounting features, such as flanges, anti-rotation tabs, and mounting holes can be incorporated on the inner and outer rings. RBC thin section ball bearings may be customized to meet your application’s demanding requirements.

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). RBC supplies airframe control bearings both in “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 other fields of application, where motions are mainly oscillatory andor with limited rotation.

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 Aerospace Bearings offers a full line of Mil Spec standards and many specialty and custom airframe control needle track rollers to the aerospace industry and all major OEM specifications. RBC airframe control needle track rollers conform to SAE-AS39901, formerly MIL-B-3990. These bearings are designed for use as track rollers with a very thick outer ring to withstand heavy rolling loads. They are corrosion protected, grease lubricated, sealed, or unsealed. Airframe control needle track roller rings and needle rollers are made from high carbon chrome steel, AISI 52100, hardened, and they are precision ground. For protection from corrosion under heavy loads, the O.D. of the bearing may be chrome plated. Exposed surfaces may be cadmium or zinc nickel plated. For improved corrosion resistance RBC also supplies bearings made of hardened stainless steel alloy, AISI 440C or AeroCres® reduced maintenance, highly corrosion resistant steel. RBC airframe control needle track rollers are available with either single or double roller paths, cylindrical or crowned O.D.s, and an optional self-aligning outer ring feature. These bearings are most commonly lubricated 80 to 100% fill in compliance with Mil-PRF-81322, Mil-PRF-23827, and Boeing’s BMS3-33 specifications.

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.
