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.

Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

Moreover, the rigidity of the metal case ensures better dimensional stability, reducing the risk of deformation under pressure. This is particularly beneficial in dynamic sealing applications where the seal is subjected to continuous movement.
