Rotary Shaft Seal CORTECO 12014730 ACM 55x68x8/10 - Oil Seal

Applications of the CORTECO 12014730 Rotary Shaft Seal

The CORTECO 12014730 rotary shaft seal is a high-performance oil seal designed for demanding automotive and industrial environments. With dimensions 55x68x8/10, this shaft sealing ring is primarily used as an engine seal and rotary oil seal in Mercedes-Benz powertrain systems, where reliable oil retention and contamination protection are critical.

Thanks to its integrated dust lip, this double lip oil seal effectively prevents external dirt and particles from entering the sealing area while maintaining stable oil sealing on the shaft. It is suitable for continuous operation in engines, gear systems, and other rotating assemblies requiring precise rotary sealing.

High Durability and ACM Material Advantages

This CORTECO oil seal is manufactured from ACM (polyacrylate rubber), a material widely preferred in the automotive industry. ACM provides excellent resistance to oils and grease, particularly mineral-based engine oils, transmission oils, and ATF fluids. It also offers strong resistance to aging, ozone, weather conditions, and UV radiation.

The B1BASL design identifies this product as a double lip oil seal, combining a primary sealing lip with a secondary dust lip. This construction improves sealing reliability, reduces shaft wear, and ensures high durability even under elevated operating temperatures. The seal operates effectively in a temperature range from -30°C up to +160°C, making it suitable for modern engine and drivetrain applications.
