RBC Bearings, Transport Dynamics Div.

RBC Aerospace Bearings offers standard and many specialty and custom designed radial ball bearings to the aerospace industry and all major OEMs. RBC’s radial ball bearings are offered in Conrad-type, full compliment, sealed and unsealed designs. These bearings are offered in ABEC 1 through ABEC 7 precision grades, pre-loaded, corrosion protected, grease-lubricated, and are available with numerous separator, ball, shield, seal, and lubrication options. Bore sizes range from 316 inch to 6 inches. Standard radial ball bearings have SAE 52100 steel rings and balls. RBC radial 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 radial ball bearings from CRES 440C to provide corrosion resistance. As an alternative to CRES rings, the entire surface of the rings can be plated with 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. RBC offers “T8” rings for superior corrosion resistance and M50, BG42 rings for high temperature applications. Some special ball materials include CRES 440C, silicon nitride, and M50 steel. RBC supplies radial 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 optimize stiffness 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 radial ball bearings may be customized to meet an application’s demanding requirements.

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 standard lined journal bearings, unlined bushings, and many specialty and custom designed products to support the aerospace industry. Journals are designed in a straight (plain) configuration with a flange to accommodate a combination of radial and axial loads with corrosion resistant materials and coatings. Journals are also offered in high temperature and water resistant series. Typical journal materials are 17-4PH and aluminum. Bearings may also be cadmium or zinc nickel plated as required. In addition, CRES 440C and Inconel® 718 are available upon request. Journal bore and flanged journal face surfaces may also be provided with various liner systems to satisfy specific application requirements. (Inconel® is a registered trademark of Inco Alloys International, Inc. and The International Nickel Company, Inc.) RBC manufacturers a number of self-lubricating liner materials, including machinable liners, that are qualified to AS81934 (formerly MIL-B-81934). In addition, over 60 other self-lubricating materials are available for specific characteristics; such as high temperature for turbine engine applications, or machinability for airframe, helicopter, and landing gear applications.

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 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. 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. The stud type airframe track roller 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 stud type airframe track roller can be supplied to AISI8620 or RBC’s proprietary AeroCres® corrosion resistant material.
