Pitch refers to the distance between the centers of two adjacent teeth. A smaller pitch allows for higher flexibility and precision, making it suitable for dynamic and compact applications.
PTFE - Regular maintenance of these spark plugs is crucial for optimal performance. Volkswagen recommends changing them every 100,000 miles. Neglecting this can lead to issues like rough idling, decreased acceleration, and even engine failure. Therefore, it's essential to adhere to the manufacturer's guidelines for replacement.
- In the realm of automotive engineering, the oil seal turbo is a critical component that ensures the smooth operation and enhanced performance of vehicles. This advanced technology, often overlooked yet integral to the engine's health, plays a pivotal role in regulating oil flow within the turbocharger system.

- In conclusion, oil seals play a critical role in maintaining the performance and longevity of machinery and equipment. By preventing leaks and contamination, they help ensure smooth operation and reduce the risk of accidents and downtime. With their diverse range of materials and designs, oil seals can be tailored to meet the unique requirements of any application. As such, it is essential to choose the right oil seal for the job to ensure optimal performance and long-term reliability.
Installation techniques must be carefully selected and executed to ensure the seal functions correctly throughout its service life. Each technique addresses specific installation needs and ensures long-term reliablity.
Conventional oil seals are the traditional seals, which can be recognised by a spring on the inside. These oil seals are made of a metal housing that contains a rubber seal. This part is often made of elastomer and comes into contact with the surface of the rotating shaft.

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.
