SKF s high performance polyure thanes com ine e cellent a rasion and wear resistance, low compression set and tear strength, and outstanding pressure ngineered to handle e treme conditions, polytetrafluoroethyl ene F and its compounds can withstand aggressive chem icals plus high temperatures and pressures. ue to their e tremely low coefficents of friction, they can also tolerate dry running conditions. plastics From engineering plastics to high performance plastics such as K, SKF s range of specialty plastic materials can meet higher temperature, chemical and mechanical property re uirements. s the world s only engineering company that develops oth earings and seals, SKF has a uni ue perspective on the interplay of elements in rotary sealing systems.

5 Nd during our years of diverse Industrial application e perience, we ve also developed a deep understanding of the conditions that affect reciprocating and static seals. sealing solutions from SKF enefit from years of research and development in sealing technology com ining materials, design and tri ology. ur in house simulation tool, SKF Simulator for seals, can e used to e plore the non linear ehaviour of various sealing materials, which helps to predict sealing performance under various engineers also apply non linear Finite lements nalysis F to simulate almost any operating condition y using different seal geometries to identify the critical areas in the design. aterials esign5 eveloping optimi ed sealing solutions re uires sophisticated testing and analytical methodology, thus SKF operates a glo al network of dedicated testing facilities. very year, these state of the art la oratories conduct thousands of tests, including dura ility, performance, contaminant e clusion, salt fog corrosion, cold fracture, pump rate, friction tor ue, dry wear, and chemical compati ility.

6 We can test seals in static and pulsating test rigs capa le of simulating harsh operating conditions, including e treme pressures and temperatures. ynamic tests are continuously monitored to verify parameters such as under lip temperature, friction force and friction tor ue, oil leakage, e trusion resist ance and a host of other conditions. esults from thousands of seal tests conducted annually provide valua le know how and a road empirical knowledge ase for failure analyses and enchmarks, ultimately leading to a consistent flow of new products and innovative you need a single seal or a high volume production run, SKF can support your needs. ur fle i le seal production model com ines moulded and machined manufacturing capa ilities to accommodate virtually any competencies in compression, in ection and transfer moulding technologies, SKF can apply the most appropriate option for your re uirements.

7 With the machined seals concept, we are also a le to provide machined seals very uickly, without tooling costs. esting anufacturing fle i ility SKF offers an array of proven shaft sealing solutions that protect earings, keep lu ricants in and improve system relia ility. t work in power transmissions across every ma or industry, SKF radial shaft seals support greater uptime in everything from the smallest high speed machine tools to the largest wind tur ines. eals for general Industrial applications vaila le in diverse designs and materials, SKF general Industrial seals include many that meet IS , S , or IN standards. SKF ru er outside diameter shaft seals resist aggressive gear o oils. SKF metal outside diameter shaft seals feature the SKF Wave lip design, which reduces friction compared to conventional straight edge radial lip seals. eals for hea y Industrial applications In heavy industries, keeping lu ricants in and contaminants out of systems is a serious challenge.

8 SKF can meet it with heavy duty metal cased seals, ru er outside diameter seals with metal inserts or ru er reinforcement, and polyurethane seals. einforced all ru er SS seals feature a harder grade material for the part of the seal ody that contacts the housing ore, improving sta ility during operation and installation. assette seals Featuring a multi lip seal, an integrated wear sleeve and high performance elastomeric materi als, SKF ud lock seals for oil or grease applica tions deliver ro ust protection from harsh contam inants. adial shaft seals esigned to seal a ially against a counterface perpendicular to the shaft or pin, a ial shaft seals from SKF include high perfor mance primary seals plus cost effective secondary seals such as ring pin seals epresenting a new generation of heavy duty sealing units for oil lu ricated track chain pins, SKF rackstar seals can help do er operators reduce machine wear, maintenance and operating costs.
