Main Description

The CORTECO 01002889 95x115x13 NBR B1SL rotary shaft seal is a high-quality oil seal ring engineered for reliable rotary shaft sealing, particularly in gearbox and drivetrain applications. Designed for automotive and industrial use, this seal ensures effective lubricant retention and protection against contamination in demanding operating environments.

Manufactured from durable NBR (nitrile butadiene rubber), the sealing lip offers excellent resistance to oils, greases and mechanical wear, making it suitable for transmission systems exposed to continuous operation and load variations. The B1SL configuration represents a double lip oil seal with an integrated dust lip, providing enhanced protection compared to single lip designs. The primary lip retains gearbox oil within the housing, while the secondary lip prevents dirt, moisture and debris from entering the sealing interface.

With dimensions 95x115x13, this shaft seal is commonly used in gearbox shafts, transmission assemblies and rotating drivetrain components where dependable technical sealing is critical. The optimized sealing geometry maintains consistent contact pressure on the shaft surface, reducing leakage risk and supporting long service intervals.

This rotary shaft seal is compatible with selected OEM applications from FIAT OM CARELLI ELEV (OEM 9288682) and Mercedes-Benz (OEM references including 0139975547, 0139977247, 0149971947, A0139975547, A0139977247). As a product of CORTECO, it meets strict quality standards required by professional B2B service operations.

The combination of NBR elastomer and B1SL double lip construction ensures high durability, effective contamination protection and reliable oil sealing, making this oil seal a dependable solution for transmission and drivetrain systems.
