Crankshaft oil seals are crucial components in an engine's sealing system, responsible for preventing oil leakage from the crankshaft. These seals are designed to keep engine oil within the crankcase and prevent contaminants from entering the engine. By maintaining proper oil levels, crankshaft oil seals play a significant role in ensuring that the engine performs at optimal levels.

Typically made from durable materials such as nitrile rubber, fluorocarbon, or silicone, crankshaft oil seals are built to withstand high temperatures, pressure, and constant exposure to engine fluids. Their primary function is to create a barrier that prevents oil from leaking out of the engine, which could lead to power loss, overheating, and even engine failure.

Crankshaft seals come in various designs, such as lip seals or radial shaft seals, and can be used in a wide range of applications, from automotive engines to industrial machinery.
