The self-drilling capability also ensures a stronger bond compared to conventional screws
- The primary function of these oil seals is to maintain the integrity of the lubricant, ensuring a constant supply to the moving parts. This not only enhances the machine's efficiency but also reduces wear and tear, minimizing the need for frequent repairs and replacements. Without proper oil seals, the oil could escape, leading to increased friction, overheating, and ultimately, machinery failure.
- Innovations in materials science have further advanced the capabilities of the small rubber gasket. Modern formulations can withstand extreme temperatures, resist chemicals, and endure physical stresses beyond the capabilities of their predecessors. As technology progresses, so too does the adaptability and effectiveness of the small rubber gasket.

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.- White rubber gaskets also find widespread use in construction, where they provide weatherproofing around windows and doors. They act as a buffer against the elements, reducing energy consumption by minimizing heat loss through gaps. In appliances like refrigerators and washing machines, these gaskets ensure a tight seal, maintaining efficiency and prolonging the product's lifespan In appliances like refrigerators and washing machines, these gaskets ensure a tight seal, maintaining efficiency and prolonging the product's lifespan

Oil seal for higher pressures
Meanwhile, rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. Moreover, they can seal a lightly damaged housing better than metal-covered seals since, in high temperatures, rubber can provide a more stable sealability.
These oil seals are the best for applications involving high temperatures. It’s suitable for temperatures between -4 degrees Fahrenheit and 392 degrees Fahrenheit. Also, it’s highly resistant to acids, dissolvent materials, and other chemicals. Viton (FKM/FPM) oil seals can run at a maximum speed of 38 m/s.
