Solid Lubricated Ball Bearings Polymer solid lubricant Graphite solid lubricant When grease is part of the problem of keeping equipment with ball bearings running smoothly, and when the best style of bearing for the application is a ball bearing, EDT offers a variety of solid lubricants that replace grease. Polymer solid lubricant Oil is impregnated into a porous polymer matrix with other additives. When balls need to roll, the oil lubricates them, with any excess lubricant getting reabsorbed into the polymer when the bearing stops turning. Food grade polymer solid lubricant is white, industrial grades of solid lubricant are gray. Whenever possible, seals are installed over the polymer solid lubricant . Graphite solid lubricant A mixture of graphite and other additives is installed around balls on the cage of a bearing, then treated with pressure and heat. A minute layer of graphite adheres to all contact surfaces of the bearing, and when balls need to turn, the graphite provides the necessary lubricity. Graphite solid lubricant is especially well suited to higher temperature installations. Various temperature formulas are available; vacuum-tolerant formulation is also available. Graphite solid lubricant is not recommended for high impact applications, nor is it rust inhibiting to the bearing metal. Where to use ball bearings: In many severe service applications* where ball bearings are traditionally installed EDT plane bearings are an excellent alternative that completely eliminate grease For more about plane bearings, refer to Sections B (Poly-Round®) and D (All-Round®) Operating conditions in which ball bearings are usually the best alternative include: High tension applications (v-belt drives, flat belt conveyors, urethane belts) High speed devices (fans, pumps, table-top conveyors) Overhung loads (shaft mounted gear reducers) Trunnion applications F-1 LT GRAY 0112 edtcorp.com [email protected] 360-574-7294 FAX 360-574-3834 EDT Corp Ball Bearing Options and EDT Part Number Identification 1 2 3 4 5 Setscrew lock stainless insert (or 300-series stainless steel) Eccentric lock stainless inserts are stocked in many sizes NCS (non-corrosive steel) treatment of a steel bearing makes insert more corrosion resistant to many liquids Polymer solid lubricant (shown without seal) Graphite solid lubricant (shown cut-away) Food grade is white J +40°F to 220°F K +15°F to 350°F B -40°F to +40°F Lube is black W -250°F - 250°F M +250°F -+450°F T +450°F - +650°F Industrial is gray H 0°F to 220°F R 15°F to 500°F Vacuum-tolerant formulas available Insert can be: solid lubricated or re‑greasable Metal and NCS eccentric lock inserts can be provided with solid lubricant Let EDT help you determine the best combination of bearing and lubricant materials depending on the specific application!
