Main Description

The 60x85x13 Rotary Shaft Seal CORTECO 01002867 NBR B1SL (82002867) is a high-quality oil seal ring designed for reliable rotary shaft sealing in transmissions, drive axles and industrial drivetrain systems. Engineered for agricultural and heavy-duty applications, this seal ensures consistent lubricant retention and effective contamination protection.

Manufactured from durable NBR (nitrile butadiene rubber), the sealing lip offers excellent resistance to mineral oils, greases and mechanical wear in standard operating environments. The B1SL configuration represents a double lip oil seal with an integrated dust lip, providing enhanced protection compared to single lip seals. The primary lip maintains oil retention inside the housing, while the secondary lip prevents dirt, moisture and abrasive particles from entering the sealing interface.

With dimensions 60x85x13, this shaft seal is commonly used in gearboxes, axle assemblies and drivetrain components where dependable technical sealing is critical. The optimized lip geometry maintains consistent shaft contact pressure, minimizing leakage risk and supporting long-term operational stability.

This rotary shaft seal is compatible with selected OEM applications from CASE IH (OEM references 3146649R1, 3146649R91) and ZF (OEM reference 0750110086). As a product of CORTECO, it meets strict quality standards required in professional B2B maintenance and service operations.

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