ROD ENDS & SPHERICAL BEARINGS selection Unibal rod ends and spherical bearings are available in a variety of types and a full range of sizes. Following is a summary of types available. To ensure optimum life and reliability it is clearly important to select a rod end or spherical bearing suited to the application. The technical information which follows is provided as a guide to selection only, although it will be adequate for simple applications involving low loads, speeds, frequencies etc. For more demanding applications please contact our technical sales staff who will always be pleased...

P R O D U C T S U M M A RY Table 1 SERIES Standard Series BEARING SURFACES Simple mechanical applications with no special demands. Steel / Bronze As standard but with chrome plated ball for reduced wear, corrosion resistance and higher operating speeds. Steel / Bronze TYPE REFERENCE As standard but offering a range of alternative threads including CETOP. Steel / Bronze High tensile steel housing to withstand high static loads. Steel / Bronze Stainless steel housing and ball for use in corrosive environments Steel / Bronze High performance series, for high resistance to static loads and...

Neoprene rubber seals sizes 6 – 22 Corrosive environment Frequent lubrication High operating speed Axial loads Axial shock loads Shock loads vibration Alternating and/or pulsatory load Table 2 compares various types of rod end and spherical bearings under different operating conditions, and will enable an initial selection to be made. Size and load considerations should then be checked by reference to the product tables on the following pages. Constant dynamic load Excellent, very well suited to indicated conditions. Not recommended for indicated conditions Self-lubricating - maintenance...

Table 4 Value of α angle The angles of misalignment (α) shown are valid for all rod end and spherical bearings. The formulæ shown in Table 4 may be used to calculate the angle α for other types of assembly The angle (α) varies depending upon the type of assembly. Table 3 indicates the maximum angular misalignment possible for the three assemblies encountered most frequently. Angles shown are rounded to the nearest whole number. Calculation formulæ NEOPRENE PROTECTIVE COVERS Material : Neoprene, to NF T 46-018 Standard. Temperature range : –30°C to +120°C Good resistance to : oil, grease,...
