All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.

The group of oil seals used in dynamic applications include radial shaft seals that seal a rotating shaft around its circumference. They are also known as lip seals, but in this blog we will use the term oil seals.
Oil leak: the most frequent failure of the oil seal

ptfe oil seal. This makes them suitable for use in applications where other types of seals may be damaged by exposure to chemicals.

If you have prepared the assembly properly, then you are already largely on your way to a successful installation. The assembly of the oil seal itself is not complex. It is, of course, important that it is done properly in view of the longevity and reliability of the seal.
The construction of an oil seal is a testament to meticulous engineering. Each oil seal primarily comprises two core components: the sealing element and the metal case. The collaboration of these parts brings about the seal’s functionality and effectiveness. A garter spring may also be included as an available feature, providing an extra layer of operational support.
What are rotary shaft seals?
Oil seals are commonly made from materials such as rubber, silicone, or polyurethane, with each material offering different properties and advantages. Rubber seals are flexible and cost-effective, making them suitable for a wide range of applications. Silicone seals offer high temperature resistance and chemical compatibility, while polyurethane seals are durable and abrasion-resistant.
