Different types of rotary shaft seals are available in the market, including radial lip, axial lip, and mechanical face seals.
Oil seals are installed beside the bearing while the flexible lip is pressed against the rotating shaft. The casing pressing into the housing holds the seal in place. The sealing lip is essentially lubricated to minimize the risk of overheating due to the generated friction.
