  • However, the new variant also comes with less good properties. Namely less flexibility and less resistance during assembly. Most damages therefore occur during the installation of PTFE oil seals.

  • When selecting spark plugs for motor vehicles, it is important to consider the specific requirements of the vehicle, including heat range, electrode design, and material composition. Iridium spark plugs are known for their fine-wire electrode and superior durability, making them suitable for a wide range of motor vehicle applications. The use of high-quality iridium spark plugs can contribute to optimized engine performance, fuel efficiency, and emissions control, ensuring reliable operation and reduced environmental impact.

  • A steering oil seal is a vital component in a vehicle's steering system, providing protection and preventing leaks of steering fluid. This small but essential part plays a crucial role in maintaining the functionality of your vehicle's steering mechanism.
  • There are several key factors to consider when selecting the right oil seal to best protect your application.

  • Overall, rubber edge gaskets are indispensable components in various industries, providing a cost-effective solution for sealing applications. With their superior flexibility, resilience, and durability, these gaskets offer unmatched performance and reliability in demanding environments. Whether in automotive, aerospace, construction, or manufacturing applications, rubber edge gaskets play a crucial role in maintaining the efficiency and safety of operations.

  • 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.
