Suitable for bearing arrangements that have to support radial loads only. For slow rotational or oscillating movements. Initial lubrication not required. Maintenance-free. \u003cbr\u003e \u003cstrong\u003e PTFE E composite: \u003c\/strong\u003e PTFE composite bearings consist of a copperplated sheet steel backing on which a 0,2 to 0,4 mm (0.008 to 0.015 inch) thick porous layer of tin\/bronze is sintered. By a rolling process, the pores of the sintered layer are filled with a mixture of PTFE (polytetrafluoroethylene) and molybdenum disulphide. An additional 5 to 30 \u003cfont face=\"Symbol\"\u003em\u003c\/font\u003em thick running-in layer of the mixture is then applied to the sintered tin\/bronze. This additional layer provides an optimum combination of the mechanical properties of the sintered tin\/bronze and the good sliding and lubricating properties of the PTFE mixture. PTFE composite bearings have\r\ngood dimensional stability and thermal conductivity.\u003c\/p\u003e","brand":"SKF","offers":[{"title":"Default Title","offer_id":52216686772565,"sku":"PCM505530E-SKF","price":28.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/1491\/3109\/files\/pcme_1a6d9c1b-f023-4dbd-a73e-d81d5b44df86.jpg?v=1780318095","url":"https:\/\/simplybearings.us\/products\/pcm505530e-skf","provider":"Simply Bearings Ltd - Ball Bearings, Oil Seals, O-rings, V-Belts, SKF","version":"1.0","type":"link"}
