Rotary Shaft Seal CORTECO 01002845 40X58X9 Oil Seal

Differential and manual transmission applications

NBR material and B1SL double lip design

Technical performance and OEM compatibility

Main description

The CORTECO 01002845 40x58x9 NBR B1SL rotary shaft seal is a high-quality oil seal designed for reliable rotary shaft sealing in drivetrain systems, including differentials and manual transmissions. Manufactured from durable NBR (nitrile butadiene rubber), this seal offers excellent resistance to oils, greases and mechanical wear, ensuring stable performance in demanding operating conditions.

The B1SL configuration identifies a double lip oil seal with an integrated dust lip. The primary sealing lip effectively retains lubricant within the differential or gearbox, while the secondary dust lip protects the sealing area from dirt, moisture and external contaminants. Compared to a single lip design, this construction significantly improves sealing reliability and extends service life, particularly in exposed or high-load drivetrain applications.

With dimensions 40x58x9, this shaft seal is commonly used in drive axles, differential housings and manual transmission assemblies where dependable technical sealing is critical. The optimized sealing geometry ensures consistent contact pressure on the shaft surface, minimizing leakage and reducing friction during continuous operation.

This rotary shaft seal is compatible with selected OEM applications from FENDT (OEM reference X550081902000) and RENAULT TRUCKS (OEM reference 5000055971), making it a proven replacement solution for agricultural machinery and commercial vehicles. As a product of CORTECO, it meets the high quality standards expected by professional B2B customers.

The combination of NBR elastomer and B1SL double lip construction ensures high durability, effective contamination protection and reliable oil sealing, supporting long-term operation of drivetrain components.
