Corteco 12011180 NBR BASL Rotary Shaft Seal 54x81x10

Description

The Corteco 12011180 NBR BASL shaft seal is a high-performance rotary shaft seal designed for demanding industrial and automotive applications. With precise dimensions of 54 mm inner diameter x 81 mm outer diameter x 10 mm height, it provides reliable sealing and long service life.

Application & Compatibility

This oil seal (simmering) is suitable for a variety of rotating shaft systems and is a trusted choice in both agricultural machinery and automotive engineering. It is compatible with Claas tractors (OEM part number 02133070) as well as certain Peugeot models (OEM reference 334522). Its robust design makes it well-suited for industrial powertrains, gearboxes, and shaft assemblies requiring effective protection against oil leakage and dust ingress.

Material Benefits & Seal Design

Constructed from NBR (nitrile-butadiene rubber), this technical seal offers excellent resistance to oils, greases, and typical automotive or hydraulic fluids. The BASL lip design (dual-lip) further enhances its performance by combining a primary sealing lip with a dust lip, ensuring reliable protection both from the inside medium (oil) and external contaminants. This design delivers high durability, minimizes oil leakage, and offers strong resistance to wear.

FAQ

1. What is the purpose of this rotary shaft seal?
This oil seal prevents the leakage of lubricants from rotating shafts while protecting the internal mechanism from contamination. It’s ideal for use in gearboxes, axles, and other rotating assemblies.

2. Why is NBR used for this seal?
NBR (nitrile rubber) is widely used in shaft seals due to its excellent resistance to oils, greases, and many industrial fluids. It also maintains flexibility and sealing integrity over a broad temperature range.

3. What does the BASL design mean?
BASL refers to a dual-lip configuration that includes a sealing lip for oil retention and a secondary dust lip to guard against external dirt and particles.

4. Can this seal be used as a replacement (OEM equivalent)?
Yes. It corresponds to OEM part numbers like Claas 02133070 and Peugeot 334522, making it a direct-fit replacement in many applications.

5. What are typical applications of this seal?
Common applications include agricultural machinery (tractors), automotive shafts, industrial gearboxes, and rotating axles that require reliable, high-durability sealing.
