CORTECO 12011398 Shaft Seal 95x120x13 - NBR B2 Oil Seal

Applications of the CORTECO 12011398 Rotary Shaft Seal

The CORTECO 12011398 (95x120x13 mm) is a high-performance rotary shaft seal designed for demanding industrial and automotive applications. Manufactured from high-quality NBR (nitrile butadiene rubber), it ensures stable operation in systems exposed to oils, greases, hydraulic fluids, and standard engine lubricants.
This shaft seal is widely used in wheel hubs, engine components, drivetrain assemblies, agricultural machinery, and heavy-duty commercial vehicles. It is fully compatible with selected models from FENDT, MAN, and Mercedes-Benz, where high durability and reliable sealing under rotational load are required.

Key Advantages and Performance Features

Engineered as a double lip oil seal (B2 profile), the CORTECO 12011398 provides improved protection against lubricant leakage and external contamination. The auxiliary dust lip reinforces shaft protection, extending service life in harsh environments such as off-road, agricultural, and construction equipment.
NBR material delivers excellent resistance to oils and grease, stable elasticity at operating temperatures up to approx. 100-120°C, and secure performance under moderate shaft misalignment or vibration. The seal offers dependable operation in both industrial applications and high-load automotive systems.

Main Description

The CORTECO 12011398 rotary shaft seal (95x120x13 mm) is a robust sealing solution engineered for precision and long service life in rotating assemblies. As a double lip oil seal, it delivers superior barrier performance by combining an effective primary sealing lip with an additional dust lip that protects the shaft against contaminants, moisture, and abrasive particles.
Manufactured from premium NBR, this oil seal provides outstanding resistance to oils, greases, diesel fuel, hydraulic oils, and common industrial lubricants. The material maintains elasticity and sealing pressure even during continuous operation, making it suitable for high-load wheel hubs, engines, agricultural powertrains, and hydraulic systems.

Its wide use as a replacement component for FENDT X550163601000, MAN 06562890111 / 06562890273, and Mercedes-Benz 0069976946 makes it a preferred choice for heavy-duty fleet maintenance, agricultural machinery repair, and industrial service operations.
The CORTECO 12011398 ensures stable performance in both high-speed and moderate-temperature rotary systems, supporting reliable operation in demanding industrial applications and automotive environments, where precision and long-term durability are essential.

Ideal for professional B2B users, the seal integrates seamlessly into existing assemblies, providing consistent sealing force, reduced leakage risk, and minimized downtime. It is an optimal replacement option for OEM shaft sealing rings requiring dependable performance and long-term resistance to wear.

FAQ - Frequently Asked Questions
