Company Profile

The SKF Economos Group is the global leader for standard and custom engineered sealing solutions, which supplies all segments of industry. It specialises in supplying customised, engineered sealing solutions and advanced engineered plastic parts. The SKF Economos Group develops and offers customer specific, innovative sealing concepts and multifunctional precision engineered parts made from advanced plastic compounds. Since 2006 SKF Economos is part of the globally renowned SKF bearings company.Activity Specified:Standard seals and custom engineered sealing solutions- for any industryCustomer specific seals from prototype (single seal) to serial- production (injection moulded) made of high performance- polymeric sealing materialsMachined Advanced Engineered Plastic Parts (AEPP) made of- high performance plastic materials for a wide range of- industrial applicationsTurnkey seal-production machines (Seal-Jet® systems)Water-Jet® cut productsCylinder repair service in addition to our seal business,- we offer a repair service for hydraulic and pneumatic cylindersProduct Range (Manufacture and Export):Due to our flexible production process, we can supply standard and special seals in customized dimensions and heavy duty sealing materials up to 4.000 mm in diameter as one piece and larger using our welding technique within shortest possible delivery times (availability permitting, from 24 hours). Our long standing experience in material development allows us to produce the highest standard of polymeric seals and meet the most demanding sealing requirements.* Piston Seals* Rod Seals* Wiper Seals* Rotary Seals* Guide Rings* Back-up Rings* Static Seals* Advanced Engineered Plastic Parts (AEPP) using sophisticated machining techniques, we can produce both simple and complex components of engineered or advanced engineered plastic parts, made of high performance plastic materials to your specific design.* Semi finished high performance sealing materials(for details please see traded material names)* Seal-Jet® machines (IP and NG-ranges incl. accessories) CNC cutting plants for plastic materials* Additionally traded products we supply a huge variety of traded components and products like o-rings, compact piston seals, radial shaft seals, guide rings, guide tapes, water cut gaskets etc.* Services: Please consider our service offer for advanced on-site consulting, product and material development, media resistance tests, finite element analysis (FEA), etc.Traded material names:Due to increasingly more complex demands on the sealing technology, material developments are gaining in importance.SKF Economos supplies 23 standard and more than 50 special materials:STANDARD MATERIALS (POLYURETHANES):ECOPUR® (TPU, green, thermoplastic Polyurethane)H-ECOPUR (TPU, red, hydrolysis-resistant thermoplastic Polyurethane)G-ECOPUR (CPU, red, cast hydrolysis-resistant thermoplastic- Polyurethane; same raw material components as H-ECOPUR- available for diameter ranges from 540 to 4000 mm as one piece,- seal dimensions from 4000 and above 8500 mm using our welding- technique)S-ECOPUR (grey, abrasion resistant thermoplastic Polyurethane;- optimised tribological characteristics (friction and wear resistance)- achieved through the addition of solid lubricants)T-ECOPUR (TPU, blue, low temperature thermoplastic Polyurethane,- minimum service temperature is extended to -50°C)X-ECOPUR (TPU dark green, thermoplastic Polyurethane with- 57 Shore D hardness, outstanding friction and wear properties- an alternative to PTFE solutions)XH-ECOPUR (TPU, dark red, hydrolysis resistant thermoplastic- Polyurethane with 60 Shore D hardness an alternative to PTFE- solutions)XS-ECOPUR (TPU, dark grey, abrasion resistant thermoplastic- Polyurethane with 57 Shore D hardness and improved sliding- properties an alternative to PTFE solutions)STANDARD MATERIALS (ELASTOMERS):SKF ECORUBBER-1 (NBR, black, elastomer based on sulphur vulcanised Acrylonitrile-butadiene rubber)SKF ECORUBBER -H (H-NBR, black, peroxyde cross linked, hydrogenated Acrylonitrile-butadiene rubber)SKF ECORUBBER -2 (FPM,FKM, brown, bisphenol cross linked- Fluororubber)SKF ECORUBBER -3 (EPDM, black, peroxyde cross linked Ethylene-- propylene-diene rubber)SKF ECOFLAS (TFE/P, black, Tetrafluoro-ethylene-propylene rubber)STANDARD MATERIALS (THERMOPLASTICS):SKF ECOFLON 1 (PTFE-virgin, white, Poly-tetrafluoro-ethylene;- semi-crystalline thermoplastic material)SKF ECOFLON 2 (PTFE with 15% glass fibres and 5% MoS2, grey,- Poly-tetrafluoro-ethylene; semi-crystalline thermoplastic material)SKF ECOFLON 3 (PTFE with 40% bronze as filler, bronze,- Poly-tetrafluoro-ethylene; semi-crystalline thermoplastic material)SKF ECOFLON 4 (PTFE with 25% carbon, black, Poly-tetrafluoro-- ethylene; semi-crystalline thermoplastic material)SKF ECOTAL (POM, black, semi-crystalline Poly-acetale-copolymer)SKF ECOMID (PA, black, Polyamide)SKF ECOPAEK (PEEK, cream coloured, Poly-ether-ether-ketone;- high-performance thermoplastic material)SKF ECOWEAR 1000 (UHMW-PE, white,ultra high molecular weight- Polyethylene; molecular weight: 4.500.000 g/mol; excellent wear- resistance and impact strength also at low temperatures down- to -200°C; semi-crystalline thermoplastic material)STANDARD MATERIALS (THERMOSETS):SKF ECOTEX (Polyester, light orange, Polyester-resin with polyester- fabric and graphite filler; excellent wear resistance and impact- strength, especially for guide rings and bearing bushes)ALTERNATIVE PTFE VARIANTS IN STOCKSKF Ecoflon, special types with organic fillersPTFE can also be compounded with organic fillers to produce- "high performance compounds", e.g. Poly-phenylene-sulfones- (PPSO2), Poly-phenylene-sulfide (PPS), Polyarylate (PAR;- "EKONOLl") or Poly-ether-ether-ketones (PEEK).SKF ECOFLON 5 (modified PTFE matrix, e.g. modified PTFE/TFM- from Dyneon)Some applications require food compatible PTFE materials.- SKF ECOFLON Ecoflon 1 and SKF ECOFLON 5 meet FDA (Food and Drug- Association) regulations.OTHER ALTERNATIVE PLASIC AND RUBBER MATERIALS IN STOCK
