Main description

The CORTECO 49390581 65x79x10 oil seal is a high-performance rotary shaft seal designed for demanding automotive and industrial applications where reliable sealing, material stability, and long service life are essential. This simmerring is intended for use as a crankshaft oil seal in selected BMW engines, corresponding to OEM number 11118618864.

The seal is manufactured using a combination of PTFE (polytetrafluoroethylene) and ACM / FPM, providing excellent resistance to engine oils, lubricants, and elevated operating temperatures. Compared to conventional rubber oil seals, PTFE-based sealing solutions offer significantly lower friction, reduced wear of the sealing lip, and extended service intervals. This results in high durability and stable sealing performance over time.

The BASLRDX7FT design includes an integrated dust protection lip, which effectively prevents external contaminants from entering the sealing area. This additional protection supports consistent rotary sealing performance, even in harsh operating environments. The seal is classified as a single-lip oil seal with enhanced protection, commonly used in modern engine designs.

With precise dimensions of 65x79x10 mm, the seal ensures accurate fit on the shaft and in the housing, which is critical for correct installation and long-term reliability. The product is suitable not only as an engine oil seal, but also as a technical sealing solution for machinery requiring dependable sealing of rotating components.

The CORTECO 49390581 oil seal is widely selected by professional workshops, automotive service centers, and industrial maintenance teams seeking a proven and durable shaft sealing solution for high-performance applications.
