4 R eim rod ends and spherical plain bearings are intended for linkage applications where a bearing must accommodate significant misalignment. hile spherical plain bearings offer flexibility in housing and mounting design, the user bears the responsibility for housing design and the cost of housing manufacture. Rod ends offer greater mounting convenience and provide a compact, lightweight, economical design alternative to the spherical plain bearing. eim earings Company offers the industry s widest selection of rod end types and sizes. Rod nd Construction eim offers three basic rod end constructions. The four piece rod end uses race inserts, typically of brass, to provide lubricity in the bearing area. This design offers reduced internal clearance, and provides smoother operation. It is ideal for dynamic applications. The two piece rod end uses a rod end body which is formed around a spherical ball. The comparatively heavy cross section of the rod end body in the two piece design provides high strength. This makes the two piece rod end ideal for highly loaded, static applications where high strength is required. The cartridge type rod end consists of a spherical plain bearing mounted in a rod end body. This design allows the optimum selection of materials for ball, race and rod end body. The cartridge type rod end can also accommodate a PT liner for selflubrication. This design is best suited for aircraft and military applications where material selection is a primary design consideration. Self-lubricating Rods nds eim produces metal-to-metal rod ends and self-lubricating rod ends. All metal-tometal rod ends, including brass insert four piece types, require regular lubrication. This can be accomplished by splash or immersion oil lubrication, or by greasing through optional lubricators (grease fittings). Self-lubricating types are used where relubrication is not practical, or in applications where relubrication is not desirable, such as on food processing machinery or in clean environments. eim self-lubricating rods ends are available with bonded PT fabric liners, or with molded, engineered thermoplastic race inserts. Rod nd Grades eim rod ends are offered in four grades: precision, commercial, aircraft, and military. Precision rod ends are manufactured to tight tolerances for applications requiring improved linkage accuracy and reduced looseness. Commercial rod ends are produced using standard materials and manufacturing methods, and are an economical choice for industrial applications. Aircraft rod ends use premium materials, and have magnafluxed rod end bodies. riginally intended for aircraft applications, aircraft rod ends are used in many industrial applications where a high degree of reliability is required. Military rod ends are produced in strict accordance with all applicable military specifications and are typically used in military and commercial aviation applications, or when Mil-Spec approval is required. Precision Rod nds Grade M and four piece precision rod ends use brass race Series Size Range M, 3/" to 1" Product eatures Precision Grade rass Inserts our Piece Construction inserts for lubricity and clearance control. They are produced to tight tolerances for applications requiring a more precise rod end; for example, a linkage where positioning accuracy is essential. These rod end bodies and balls are plated for corrosion resistance. Series M, X G and MX G four piece precision extra capacity rod ends are the high strength series intended for more heavily loaded, static and dynamic industrial applications. These rod ends have heat treated bodies for increased strength and aluminum bronze race inserts for high bearing capacity. The rod end bodies are protective coated for corrosion resistance and the balls are chrome plated for superior wear and corrosion resistance.

14 R CM C IM Self Lubricating Series nvironmental Characteristics or commercial applications where a self-lubricating bearing is either desirable or necessary, eim developed eim Series bearings. eim bearings are designed with an engineered thermoplastic race material and offer a lower coefficient of friction than metal-to-metal types that use conventional lubricants. It is a resilient material that performs well under vibratory and dynamic loading and withstands dynamic loads up to 3500 PSI. here to Use IM earings eim bearings should be used in applications where the bearing cannot be periodically lubricated or where it is desirable to eliminate the need for regular maintenance. They are also recommended for applications where there is considerable vibration. The resilience of the engineered thermoplastic race absorbs vibration without causing fretting or galling of the surface. The torque level of the bearing will be low because of the low coefficient of friction of the hardened steel ball on the engineered thermoplastic race. The coefficient of friction for eim bearings is approximately 0.1, but will vary somewhat depending on the loads, speeds, temperatures, and solvents that are present. The chart on this page shows a typical bearing wear pattern of eim bearings and how they vary with number of oscillations. ear in Inches eim bearings have good environmental tolerances. They offer advantages over bearings that use a nylon race because the eim engineered thermoplastic race absorbs very little moisture. It is generally resistant to alcohols, aldehydes, esters, ethers, hydrocarbons, weak acids and bases, water and agricultural chemicals. imensional stability is quite good when exposed to these substances, however the eim engineering department should be contacted for recommendations on specific performance characteristics. ear vs. scillations 4 PM 2 PM,000 0, ,000 scillations (+/- radial rotation) This chart shows typical wear of engineered thermoplastic race bearings (load at one-half static rating - ball surface velocity as noted),
