The significance of chemical studies extends far beyond academic pursuits
- The primary function of a mechanical oil seal is to create a barrier between the rotating shaft and the stationary housing, preventing the escape of oil and other lubricants. This helps to maintain proper lubrication levels within the equipment, reducing friction and wear on moving parts. Additionally, oil seals help to prevent contamination of the lubricant by dirt, dust, and other contaminants that can lead to premature wear and equipment failure.
Fluid Types - Various oil seals are able to withstand interactions with oils, fuels, grease, water and more. Knowing what type of fluid the rotary shaft seal will be in constant contact with will ensure the longevity of the seal and surrounding components.

thick rubber gasket. This makes them ideal for outdoor and harsh environment applications where other materials may deteriorate quickly. Additionally, rubber gaskets are non-conductive and can provide an effective barrier against electrical currents, reducing the risk of electrical hazards.
Type of Fluid
Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.
As type B with dust lip
Aflas is created from fluoroelastomers (FKM), providing the following benefits:
3. Poly acrylate

ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
