  • The selection of the right high pressure oil seal is critical

  • PTFE is special in that a pre-tensioned spring is not required. This is because the material returns to its original shape when heated, also known as the shape-memory polymers (SMPs) effect. These oil seals are also supplied as integrated parts, where it only needs to be installed as one component.

  • When it comes to keeping your engine running smoothly and efficiently, having the right spark plugs can make all the difference. And one spark plug that has been gaining popularity among automobile enthusiasts and professionals is the FF 10 spark plug.
  • The dimensions 35x50x8 denote the primary characteristics of this particular oil seal. The first two numbers, 35 and 50, represent the outer diameter and the inner diameter respectively, specifying the sizes at which it can effectively function. The final number, 8, indicates the thickness or the cross-sectional dimension of the seal. This design allows for a snug fit in various applications, creating a robust barrier against fluid escape and foreign particle intrusion.

  • Oil seals are vital to the daily operation of most factories and a wide range of industrial and commercial equipment. They are available in imperial and metric dimensions for both single- and double-lip design. Motors, Mechanical Hydraulic systems, pistons, and pumps utilize oil seals to protect internal components. Depending on the application, there are various material, size, and configuration options to best fit your needs. Learn more about oil seals, their composition, and the wide range of advantages they offer for your equipment.

  • In general, oil seals should be selected in the order of priority indicated in Table 1.

  • A rubber or PTFE sealing lip

  • Requirements of the shaft
    Even more important than a correct interference fit of the Oil Seal is a perfectly smooth shaft in the region of the seal, particularly if shaft surface speed is high and the medium to be sealed is under a certain amount of excess pressure. The surface roughness of the shaft depends on the average profile depth Ra of the tool marks caused by the machining process. Oil Seals made of PTFE require, independent of the surface speed, a surface roughness of between 0,1 to 0,2 mm, because PTFE has less wear resistance than rubber seals. For normal circumstances, the shaft in the region of the seal must have a surface roughness of approximately:  To summarize, the surface of the shaft in the region of the seal should not have noticeable machining marks. For pivoting shafts and other difficult or critical sealing applications, it is recommended that Oil Seals with a helical groove hydrodynamic pattern, which has a pumping effect, be used. When grinding and polishing, an axial movement of the grindstone along the shaft must be avoided in order to prevent machine lay.
