Description
The crankshaft seal is used to retain engine oil and prevent external contaminants from entering the engine oil system.
Seals for dry applications (air-to-oil interface) typically include a primary sealing lip that prevents engine oil leakage and a dust lip. In wet applications (oil-to-oil interface), the dust lip is replaced with an auxiliary lip that can pump external fluid away from the engine. Some seals have a plastic sleeve to assist with the installation process.
Features
Cat® crankshaft seals are precisely engineered for the most demanding applications and withstand high speeds, high temperatures and frequent axial movement.
Cat® sealing systems go through a robust design, testing and validation process. Protect your investment with the latest Genuine Cat® seals.
Applications
The crankshaft seal is used on engine crankshafts and in other high-speed rotating applications, such as some water pumps.
