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,

as well as a dust lip and wear-resistant sleeve.

In wet applications (fluid to fluid interface), the dust lip is replaced with an auxiliary lip that can extract external fluid from the engine.


Cat The crankshaft seal assembly is precisely designed according to the requirements of extremely demanding applications.


They must be able to withstand high rotational speed, high temperature, and high-frequency axial motion.

The crankshaft seal assembly includes a wear-resistant sleeve that prevents crankshaft wear and provides the best contact surface for lip seals.

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

Cat The sealing system can prevent leakage and contamination of more expensive parts. Please use Cat Original seals protect your investment.


The crankshaft seal assembly is used for engine crankshafts and other high-speed rotating applications, such as some water pumps.

Attention: The entire crankshaft sealing assembly should be replaced as a whole and should not be repaired separately.
