Oil seals come in various designs depending on the specific requirements of the machinery. The 20x30x7 oil seal, for example, is a standard radial shaft seal that is installed along the shaft to prevent oil from leaking out or contaminants from entering the machinery. This type of seal is commonly used in engines, gearboxes, and other rotating equipment where the sealing of fluids is essential.

Cassette oil seals are constructed with high-quality materials to withstand extreme conditions such as high pressure, temperature fluctuations, and abrasive substances. They usually consist of a hard wearing face material, like carbon or tungsten carbide, paired with a flexible elastomeric component, often made of rubber or polyurethane, that seals against the shaft.

In addition to preventing oil leakage, cylinder oil seals also help to prevent contamination. Contaminants such as dirt, dust, and moisture can enter the cylinder and cause damage to the internal components. This can lead to reduced efficiency, increased maintenance costs, and a shorter lifespan for the machinery. By creating a tight seal around the cylinder shaft, oil seals help to keep contaminants out and protect the internal components from damage.
