The latest series of standalone machine systems for the manufacture of precision machined seals from SKF, the knowledge engineering company, is providing even faster service in the delivery of customised seals in exceptionally high grade polymers. These materials, which have all been developed by SKF, are helping to cut costs for OEMs and end users alike, across many different applications by providing outstanding resistance to heat, chemicals together with a range of other challenges.
SKF seals are manufactured from advanced engineering plastics, including PTFE (polytetrafluoroethylene), HNBR (hydrogenated acrylonitrile butadiene rubber) and FKM (fluoro-rubber). Through close cooperation with SKF, engineering companies can discover and commission the optimal, tailor-made sealing solution for their needs.
PTFE is a thermoplastic polymer that offers superior chemical resistance to that of any other material used in conventional seals. The operating temperature of PTFE extends from -70
