CORTECO 12013362 NBR B2 63.6x90x11 Rotary Shaft Seal

Applications - Iveco Drivetrain and Industrial Shaft Sealing

The CORTECO 12013362 NBR B2 63.6x90x11 rotary shaft seal is designed for reliable rotary sealing in commercial vehicle drivetrain systems. It is compatible with OEM reference Iveco 9988946, making it a trusted replacement solution for workshops and fleet maintenance operations.

This oil seal is commonly installed in gearboxes, axle assemblies, and other rotating shaft systems where secure oil retention and contamination protection are essential. It supports long term performance in demanding automotive and industrial applications.

Advantages - NBR Material and B2 Double Lip Design

Manufactured from NBR (nitrile butadiene rubber), this technical seal offers excellent resistance to oils and grease typically used in transmission and axle systems. NBR provides reliable elasticity and durability within standard automotive operating temperatures.

The B2 design indicates a double lip oil seal. In addition to the primary sealing lip with a garter spring, it includes a secondary dust lip that improves protection against dirt and external contaminants. This configuration enhances sealing reliability and contributes to high durability in heavy duty environments.
