CORTECO 12003292 NBR B2 62x80x10 mm Rotary Shaft Seal

CORTECO 12003292 NBR B2 62x80x10 mm Rotary Shaft Seal

CORTECO 12003292 is an NBR radial rotary shaft seal with a B2 profile and dimensions 62x80x10 mm. It is catalogued as a shaft sealing ring for wheel hub applications. OE references include MAN and MERCEDES-BENZ numbers, making the manufacturer reference and OE numbers particularly useful when identifying the correct replacement seal.

Technical Data - CORTECO 12003292

Dimensions

The complete dimensions are:

62x80x10 mm

where:

• 62 mm - inside diameter
• 80 mm - outside diameter
• 10 mm - width

All three dimensions should be verified when selecting a replacement, together with the B2 profile, NBR material and OE reference.

B2 Profile

CORTECO specifies the seal construction as:

B2

The profile is an important part of the technical specification. A different oil seal with dimensions 62x80x10 mm should not automatically be considered equivalent to CORTECO 12003292.

For reliable identification, use the complete specification:

CORTECO 12003292 + NBR + B2 + 62x80x10 mm

NBR Material

CORTECO 12003292 is manufactured from:

NBR - nitrile butadiene rubber

NBR is widely used in radial shaft seals because of its good resistance to many mineral oils and greases commonly found in mechanical systems.

However, NBR is not universally resistant to every lubricant or chemical. Compatibility should be checked when the seal operates with an unusual oil, grease or other medium.

A specific operating temperature range should not be assigned to this exact seal solely from general NBR material data.

Rotary Shaft Seal for Wheel Hub

CORTECO 12003292 is catalogued as a:

rotary shaft sealing ring for wheel hub applications

In a wheel hub assembly, the seal helps retain the appropriate lubricant and limit the ingress of contamination through the sealing position.

The performance of a new seal also depends on the condition of the complete mechanical assembly, particularly the shaft running surface, bearings, hub play and alignment.

MAN OE Reference

The following MAN OE reference is specified for CORTECO 12003292:

06562790147

This reference can be used when identifying the seal in MAN parts catalogues and vehicle applications.

MERCEDES-BENZ OE References

The following MERCEDES-BENZ references are associated with CORTECO 12003292:

• 0019977747
• 0069972646
• A0069972646

The references 0069972646 and A0069972646 represent the MERCEDES-BENZ part-number format with and without the A prefix.

Compatibility should still be confirmed for the exact vehicle, axle and wheel hub configuration.

Identification by OE Number

If the marking on the removed seal is unreadable, the OE number can provide an important additional identification criterion.

Relevant references include:

MAN 06562790147

MERCEDES-BENZ 0019977747

MERCEDES-BENZ 0069972646

MERCEDES-BENZ A0069972646

The presence of an OE number in the cross-reference data does not replace verification for the specific vehicle or axle version.

Why Dimensions Alone Are Not Enough

Different rotary shaft seals can share the same:

62x80x10 mm

dimensions while having different technical constructions.

They may differ in:

• profile
• elastomer material
• sealing lip design
• outside surface construction
• intended application
• OE references

For this reason, the complete designation:

CORTECO 12003292 NBR B2 62x80x10 mm

provides a much safer basis for identification than dimensions alone.

Wheel Hub Inspection Before Installation

Before installing a new seal, inspect the complete wheel hub assembly.

Check:

• sealing surface condition
• wheel bearing condition
• radial play
• axial play
• mounting surface
• alignment
• corrosion
• scratches and wear grooves
• possible cause of the original leakage

If leakage is caused by excessive bearing play or damage to the mating surface, replacing the seal alone may not solve the problem.

Installation

The sealing lip should be protected against cutting, folding or other mechanical damage during installation.

The seal should be installed:

• evenly
• square to the housing bore
• using a suitable installation tool
• to the correct installation depth

For wheel hub applications, the installation procedure specified for the particular vehicle or axle assembly should be followed.

How to Select CORTECO 12003292

Before ordering, verify:

1. CORTECO part number - 12003292.
2. Inside diameter - 62 mm.
3. Outside diameter - 80 mm.
4. Width - 10 mm.
5. Profile - B2.
6. Material - NBR.
7. MAN or MERCEDES-BENZ OE number.
8. Construction of the removed seal.

Identical 62x80x10 mm dimensions alone do not confirm full interchangeability.
