Oil seal or shaft seal is a device that prevents the passage of fluids along a rotating shaft. Seal needed when a shaft extend from a housing / enclosure containing oil such as pump, engine or gearbox. Seal is made from elastic material like rubber or elastomer. The sealing is done by a lip on the ring that is pressed around the shaft by a helically wound garter spring. The installation of the oil seal is also explained.
