5 With theemphasis on quality throughout the process, weproduce oilite bearings with large interconnectedpores vital for the channeling of lubricants to areasbetween the shaft and bearing . At rest, the capillaryaction will recover lubricant from the surface andreplenish the reservoirs. This porosity feature of Oiliteis the most sought-after quality of our P/M PROCESSFine powders are combined and blended into a mixand are compacted in a die under high pressure. Thecompacted parts are sintered at high temperature ina protective atmosphere belt furnace. Sintered partsare then sized to obtain the exact dimensions andclose tolerances desired. The final step in the P/Mprocess is vacuum impregnation of the bearings, orfilling the pores with PROPERTIES* oilite bearing MATERIALSC omposition - - - MAXBALANCEBALANCELEAD GRAPHITE0 - - - ACID INSOLUBLES (MAX.)

Large porestructure complete with complete alpha phasebronze and twinning. Most widely used of all Oilitebearing in appliances, business machines, cylinders,exercise apparatus, lawn and garden equipment,medical applications, material handling, packagingand printing machines, and PLUSThe advantage of oilite Plusis realized in applicationsin which mixed-film, and boundary lubrication isexhibited.

8 These kinds of conditions occur in well over75% of all self-lubricating bearings oscillation or slow speed, intermittent use,pulsating or uneven loads are conditions that inhibitfull-film lubrication from developing or beingmaintained. These applications would benefitsignificantly from using oilite Plusfeatures a complex bearing system thatgreatly reduces friction. The impregnation of thebearing includes a finely dispersed PTFE in anoxidation and corrosion inhibiting turbine oil. Onaverage a 17% reduction of friction will result insmoother and quieter operation, easier break-in ,lower power requirements and longer include all equipment in the Oilitesection with emphasis on agricultural andconstruction equipment, material handlingmachines, man-lifts and computer OILITESelf-lubricating, harder, higher strength andgenerally more economical than oilite bronze, but a lower speed rated bearing material for generalapplication.

9 Recommended for high loadapplications at low in farm equipment, off-road equipment,winches, sheaves, conveyors, pulleys, oilite 16 Self-lubricating. Similar metallurgically to SuperOilite, but heat treated to a particle hardness greaterthan Rc50. High compressive strength for extremeload, low speed reciprocating and oscillatingapplications. Requires hardened steel in earth-moving equipment, cranes and hoists,railway brake rigging, presses, conveyors, AND SPEEDSThe best method for evaluating the acceptability ofOilite bearings for any given application is by usingPV factor (Pressure x Surface Velocity) where:P = the load in (psi) on the projected bearingarea ( bearing ID x Length).
