CATERPILLAR part description
PTFE Lip seal
- US
- METRIC
Description:
Crankshaft Seals retain engine oil and prevent external contamination from entering the engine oil system.
Seals designed for dry applications (air-to-fluid interface) typically include a primary lip that prevents engine oil from leaking, and a dust lip. In wet applications (fluid-to-fluid interface), the dust lip is replaced by an auxiliary lip capable of pumping external fluid away from the engine. Some seals have a plastic sleeve to aid in the installation process.
Attributes:
Cat® Crankshaft Seals are precisely designed to perform in this very demanding application. They must be able to withstand high rotational speeds, elevated temperatures, and high frequency axial motion.
Cat® sealing system uses a robust design, testing, and validation process. Buy the latest Genuine Cat® seal to protect your investment.
Applications:
Crankshaft seals are used on engine crankshafts and other high speed rotating applications, like some water pumps.

- Primary Sealing Material: Plastic
