CORTECO 01003386 NBR B2 80x120x13 mm Shaft Seal

Applications

The CORTECO 01003386 NBR B2 shaft seal (80x120x13 mm) is designed for industrial and automotive applications where a reliable rotary shaft seal is required. The nitrile-butadiene rubber (NBR) material delivers excellent resistance to mineral oils, greases and other common lubricants. With internal diameter 80 mm, external diameter 120 mm and width 13 mm, this seal fits standard industrial housings, bearing units (jednostka łożyskowa) or bearing housings (obudowa łożyskowa). It is referenced under OEM number VOLVO 967941, which reflects its compatibility with heavy-duty drivetrain systems and propulsion units. Ideal for use in gearboxes, industrial drives, conveyors and hydraulic machines, this sealing ring offers both durability and precision in demanding industrial environments.

Advantages

The CORTECO 01003386 seal stands out through several key benefits:

• High durability: The NBR elastomer ensures long service life even under continuous exposure to oils and lubricants, reducing downtime and maintenance cost.

• Proven construction (type B2): The B2 design offers effective sealing of rotating shafts, preventing leakage and ingress of contaminants, essential in industrial sealing applications.

• Standardised size for ease of replacement: The 80x120x13 mm dimensions allow fast fitment into existing bearing units or housings without major modifications, supporting efficient maintenance workflows.

• Industrial-grade reliability: Suitable for heavy duty and industrial applications, the seal ensures stable performance in units where high durability and robust sealing are required.

• B2B supply readiness: As a professional component, it supports procurement and engineering operations, offering logist-friendly sizing, clear specification and compatibility with OEM systems.

FAQ

Q1: What is the significance of the “B2” designation in this shaft seal?
A1: The “B2” denotes a specific construction type of the shaft seal, referring to a standard design of rotary sealing ring with a contact lip and sealing arrangement suitable for many industrial and automotive shafts.

Q2: Is the material NBR suitable for use with oils and greases?
A2: Yes. NBR (nitrile-butadiene rubber) exhibits strong resistance to mineral oils, hydraulic fluids and grease. It is a common elastomer for sealing applications in industrial drives and vehicle transmissions.

Q3: Can this seal be used within an existing bearing housing unit without modification?
A3: Yes. The standard dimensions 80x120x13 mm allow seamless integration into bearing units or bearing housings that match these sizes, which helps minimise downtime during replacements.

Q4: What types of applications does this shaft seal support?
A4: The seal is suitable for gearboxes, industrial drives, heavy-duty engines, conveyor systems, auto-motive driveline components and any application where rotary shaft sealing is required with high durability.
