The crankshaft seal assembly is used to maintain engine oil to prevent external pollutants from entering the engine oil system.

The sealing assembly for dry applications (air oil interface) typically includes a main sealing lip to prevent engine oil leakage,

The wear-resistant sleeve can also avoid costly crankshaft repair or replacement, making maintenance easier, faster, and more economical.
