RBC Bearings, Transport Dynamics Div.

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 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.

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. For more information on airframe control needle track rollers, please consult RBC Customer Service at 866.RBC.AERO (866.722.2376).

RBC Aerospace Bearings offers Mil Spec standards and many specialty and custom stud type airframe track rollers to the aerospace industry and all major OEM specifications. RBC stud type airframe track rollers conform to SAE-AS39901, formerly MIL-B-3990. These bearings have been designed for specific use on track type or cam-controlled equipment when cantilever mounting is desired. They are corrosion protected, grease lubricated and, typically, sealed. Stud type airframe track roller outer rings and needle rollers are made from high carbon chrome steel, AISI 52100. They are hardened and precision ground. The O.D. of the outer ring is chromium plated in accordance with the AMS-QQ-C-320, Class 2 specifications to a minimum of .0004”. Stud type airframe track rollers are available with cylindrical or crowned outer rings. 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 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.
