Aurora Bearing Commerical Catalog - AURORA BEARING - #3

steel may be employed as options for the ball component.

The three-piece style consists of a body, ball and race. This type of unit, offering fully swaged bearing construction, features the advantages of maximum spherical conformity between the ball and race. It also offers flexibility in that many different types of materials can be interchanged in each component part, provid­ing combinations that can be tailored to meet just about any application requirement.

Consult our engineering department for materials to fit your special application. Materials used in the standard catalog items are outlined on the appropriate detail page.

These bearings incorporate the single piece race type con­struction, also providing excellent ball-to-race conformity. They can be re-lubricated through an annular groove in the outer race with two interconnecting holes positioned at 180 degrees. Various metals may also be substituted in these types of units to meet special requirements. Recommended housing bores are given on pages 47-49.

PTFE (bonded coated PTFE liner) lined races are available in all three-piece bearing units and all spherical bearings. The steel race has a self-lubricating liner; a PTFE impregnated woven fab­ric, chemically bonded to the inner diameter of the race. Aurora Bearing offers two major liner style options: both are mainte­nance free and offer improved frictional characteristics.

AT1400 is supplied as the standard liner in all except the mili­tary specification bearings. It is designed primarily to satisfy the demands of the commercial/industrial market as well as most high performance applications. This liner can be used in temper­atures ranging from -65° to +250° F.

AT3200 is an ultra-high performance liner fully qualified to SAE-AS81820(formerly MIL-B-81820), developed for military and aircraft/aerospace applications. This liner offers higher load car­rying capacity as well as greatly increased dynamic wear charac­teristics and can be used in temperatures ranging from -65° to +325° F. This liner is now standard on all military specification bearings manufactured by Aurora Bearing, as well as certain high performance commercial bearings as used in the automotive rac­ing industry. It can also be specified on other lined products manufactured by Aurora Bearing where demanding applications require its superior performance characteristics. Aurora Bearing also has available a variety of alternate liner configurations to suit special requirements.

In 1971 a new company entered the rod end and spherical bearing marketplace. This new firm, Aurora Bearing Company, soon became a major force in the rod end industry.

Known primarily for a high quality product and a strong com­mitment to customer service, the firm dramatically increased its market coverage and now serves nearly every industry and aero­space market. These markets include among others: textile and packaging machinery, machine tools, business machines, recre­ation and exercise equipment, agricultural and off highway vehi­cles, commercial transportation and high performance racing vehicles as well as military equipment and commercial air and space craft.

Over the years, Aurora Bearing has retained its original busi­ness philosophy of furnishing a high quality product at competi­tive prices. In addition, the company's initial goals of providing prompt delivery and furnishing service with a personal touch have been rigidly maintained.

Aurora Bearing offers a complete line of standard rod end and spherical bearings. We also design and manufacture special bearings to meet a variety of applications that require custom engineered units or special materials.

Now marketing products worldwide, Aurora Bearing fields a very competent sales force that is available to assist and provide you with a practical and sound solution to rod end and spherical bearing application problems and challenges.

Aurora Bearing Company rod ends are manufactured utilizing two construction styles. They are of the two or three-piece type. Both are made with the solid, or one-piece, race construction method and feature the advantages of metal-to-metal contact between bearing components. (PTFE to metal interface may also be incorporated when specified).

The standard two-piece style consists of a body and precision ground oil impregnated sintered steel ball. This type of construc­tion allows the rod end body to carry a greater radial static load and the oil-impregnated ball is self-lubricating under normal oper­ating conditions. This unit also offers greater misalignment capa­bilities. A variety of materials and plating options for the compo­nent parts in this series are available. Any cold-formable steel in stainless and alloy steel categories can be specified for the body, and all hardenable alloys such as 52100 and 440C stainless
