CORTECO 01003459 NBR B2 110x128x9 mm Shaft Seal

Applications

The CORTECO 01003459 shaft seal (110x128x9 mm) is designed for heavy-duty industrial and automotive applications requiring a robust rotary shaft seal. Made of NBR (nitrile-butadiene rubber), the seal offers excellent resistance to mineral oils and greases, making it suitable for duties in gearboxes, bearing units and bearing housings where axial or radial shaft sealing is critical. With standard dimensions—inner diameter 110 mm, outer diameter 128 mm and width 9 mm—the product is easily integrated into bearing assemblies and obudowy łożyskowe without major design changes. OEM equivalents SAF 4373000200 and SAURER 4373000200 further confirm compatibility with industrial and automotive drive systems.

Advantages

This shaft sealing ring delivers multiple benefits for B2B buyers:

• High durability: The NBR elastomer resists lubricants and oils typical of industrial gearboxes, reducing wear and maintenance intervals.

• Reliable sealing construction (type B2): The B2 design ensures a proper lip seal for rotating shafts and limits contamination ingress, supporting longer service life.

• Standard dimension for easy maintenance: The 110x128x9 mm size allows quick replacement in bearing units or housing assemblies, supporting efficient service in manufacturing environments.

• Industrial-grade readiness: Designed for applications in heavy equipment, production machinery and automotive drivetrain assemblies where sealing performance and lifespan matter.

• Procurement-friendly details: Clear technical specification helps maintenance teams and purchasing managers specify the correct component in industrial catalogs.

FAQ

Q1: What does the “B2” designation mean in this shaft seal?
A1: “B2” refers to the construction type of the rotary shaft seal, specifying lip geometry and sealing arrangement suited for rotating shafts and housing assemblies.

Q2: Is NBR material suitable for use with oils and industrial lubricants?
A2: Yes. NBR (nitrile-butadiene rubber) has good resistance to mineral oils, greases and standard industrial lubricants, making it a common choice for rotary sealing applications.

Q3: Can this seal be installed in existing bearing housing units (jednostka łożyskowa) without modification?
A3: Yes. The standard size 110x128x9 mm allows direct replacement in many bearing units or housing assemblies built to that specification, enabling faster maintenance.

Q4: In what types of applications is this seal typically used?
A4: It is suitable for gearboxes, industrial drives, bearing units, rotating shafts in heavy machinery, automotive drivetrain components and other systems requiring high durability and seal integrity.
