The new product selection guide in this catalogue simplifies the selection of bushings from our expanded range for you. We can work with you to evaluate sealing variations on your test rig, or on our own virtual test rig which uses 3-D modelling software to simulate seal and bearing performance under a variety of conditions. PTFE seals are suitable for use in harsh environments with tem-peratures ranging from cryogenic to 300 °C in combination with highly aggressive media. Just enter the part number and click Search. Want to learn more about what is driving change in the engineering world? SKF PTFE polyamide bushings (fig. allows for look-up of any SKF CR Seals Part Number that is part of the current CR Seals Handbook. SKF Spectraseal profiles are predominately used for extreme and demanding application requirements where conventional moulded elastomers or thermoplastics cannot be used due to material limitations. In addition, to avoid fretting corrosion from separation of the TBU inner ring side face and axle backing ring due to axle bending, a polymer spacer with a special stiff and high creeping- and compression-resistant fiber-reinforced polyamide is used (fig. Full complement cylindrical roller bearings by definition have no cage. Croatian rolling stock producer Koncar KEV has finalized an agreement with SKF for the supply of bearings, axleboxes and associated equipment for its, Hybrid bearings have shown good performance in poor lubrication and contaminated conditions, but the understanding of the contributing mechanisms and, Cycling has been part of every Summer Olympic Games since the birth of the modern Olympic movement at the 1896 Summer Olympics, which included a road. Requires good lead-in chamfer if hardware is installed lip first. Radius lip reduces seal lip damage during installation. Parker’s FlexiLip™ seals utilize PTFE lip materials in rotary shaft applications where elastomeric lip materials fail to meet operating requirements such as temperature range, chemical resistance or friction and are an economical alternative to mechanical seals. SKF SLC spring loaded seals product line.
