Rotary Shaft Seal CORTECO 12013182 NBR B1SLSF 150x170x13.2

Applications of CORTECO Rotary Shaft Seal 12013182

The CORTECO 12013182 rotary shaft seal is designed for reliable shaft sealing in demanding industrial and agricultural applications. This oil seal features a double lip design, combining a primary sealing lip for oil retention with an integrated dust lip that protects the system from external contamination.

The seal is widely used in drivetrains, gearboxes, axles and engine-related assemblies in machinery and vehicles from manufacturers such as DANA, LANDINI and MASSEY FERGUSON. It is suitable for applications where effective rotary sealing and long-term operational stability are essential.

Advantages of CORTECO B1SLSF Oil Seal

Manufactured from NBR (nitrile butadiene rubber), this rotary shaft seal offers excellent resistance to oils and grease, making it ideal for continuous operation in lubricated systems. The material provides good elasticity, dimensional stability and consistent sealing performance across a wide range of working conditions.

The B1SLSF design represents a double lip oil seal, where the additional dust lip improves protection against dirt, moisture and airborne particles. This results in high durability, reduced wear of the shaft surface and extended service life of the entire sealing system. Precision manufacturing ensures reliable installation and secure seating in the housing.

Main Product Description

The CORTECO 12013182 NBR B1SLSF rotary shaft seal 150x170x13.2 is a professional shaft sealing ring developed for reliable oil retention and contamination protection in rotary applications. Its double lip construction ensures effective sealing against lubricants while the secondary dust lip prevents ingress of external particles.

Thanks to the use of high-quality NBR, the seal demonstrates strong resistance to oils and grease commonly used in industrial and automotive systems. The precise geometry of the sealing lips supports stable contact pressure on the shaft, minimizing leakage and wear during long-term operation.

This rotary oil seal is a proven choice for technical sealing in industrial applications, agricultural machinery and drivetrain components, where durability, compatibility and consistent performance are critical for B2B customers and maintenance professionals.

FAQ - Frequently Asked Questions

What is the difference between a single and double lip oil seal?
A double lip oil seal includes an additional dust lip that protects against contamination, improving durability.

Is NBR suitable for oil sealing applications?
Yes, NBR offers excellent resistance to oils, grease and standard industrial lubricants.

How do I select the correct rotary shaft seal size?
The inner diameter must match the shaft, and the outer diameter must fit the housing bore.

Can this seal be used in agricultural machinery?
Yes, it is commonly used in agricultural and industrial equipment.

Does this seal require additional lubrication?
No, it operates within the lubricated system and does not require separate lubrication.
