The complete product identification is:

CORTECO 01026493 NBR BASLX7 64x80x11.5/16 mm

CORTECO 01026493 Dimensions

The nominal dimensions are:

64x80x11.5/16 mm

where:

• 64 mm - inside diameter
• 80 mm - outside diameter
• 11.5 mm - primary axial dimension
• 16 mm - second axial dimension

Because of its BASLX7 profile and 11.5/16 mm stepped axial dimensions, this product should not be identified simply as a generic 64x80 oil seal.

Some aftermarket catalogues may round the first axial dimension to 12 mm. For precise identification, use the CORTECO specification:

64x80x11.5/16 mm

BASLX7 Seal Design

CORTECO identifies the construction of this sealing ring as:

BASLX7

The construction designation is important when selecting a replacement.

Seals with the same 64 mm inside diameter and 80 mm outside diameter can differ in:

• sealing-lip geometry
• axial dimensions
• elastomer material
• main sealing-lip construction
• additional dust protection
• installation geometry
• intended application

Matching the basic 64x80 mm diameters does not automatically confirm interchangeability.

NBR - Nitrile Butadiene Rubber

CORTECO 01026493 is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is one of the most widely used elastomers in industrial and automotive sealing technology. Suitable NBR compounds provide good resistance to many:

• mineral oils
• lubricating greases
• lubricants
• fluids encountered in compatible mechanical applications

NBR also provides mechanical properties suitable for many shaft and rotating-component sealing applications.

Exact temperature limits and chemical compatibility depend on the specific NBR compound and operating conditions.

A universal NBR temperature range should therefore not be treated as the confirmed operating limit for this specific CORTECO seal without the corresponding manufacturer specification.

Additional Dust Lip

CORTECO 01026493 features an additional dust lip.

Its purpose is to help limit the ingress of external contamination into the primary sealing area.

The dust lip provides additional protection against contaminants such as:

• dust
• dirt
• fine particles
• road contamination
• external debris

This feature is particularly relevant for steering knuckle and axle-related applications where the sealing area may be exposed to external contamination.

CORTECO 01026493 Steering Knuckle Seal

CORTECO 01026493 is catalogued as a steering knuckle seal.

The steering knuckle is located in an area of the vehicle where mechanical components can be exposed to road dirt, dust and other external contaminants.

The sealing arrangement must therefore be correctly matched to:

• shaft or mating-component diameter
• housing diameter
• installation width
• sealing profile
• elastomer material
• dust protection
• application geometry

For replacement purposes, identification by the CORTECO or Mercedes-Benz OE reference is preferable to selection by dimensions alone.

CORTECO 01026493 Stub Axle Seal

The product is also catalogued internationally as a stub axle seal.

A stub axle sealing arrangement requires accurate dimensional and construction compatibility.

For CORTECO 01026493, the combination:

64x80x11.5/16 mm

NBR

BASLX7

provides much more precise product identification than simply searching for a 64x80 mm oil seal.

CORTECO 01026493 Mercedes-Benz 0229970047

The principal Mercedes-Benz OE reference associated with this seal is:

Mercedes-Benz 0229970047

This OE number can be used when identifying the required steering knuckle or stub axle seal.

Before installation, compatibility with the exact vehicle, axle and assembly should be confirmed.

CORTECO 01026493 Mercedes-Benz A0229970047

The Mercedes-Benz reference is also listed as:

A0229970047

Therefore, both search formats are relevant when identifying this product:

0229970047

and

A0229970047

The combination of the Mercedes-Benz OE reference and CORTECO number provides a more reliable identification than dimensions alone.

OE and Cross References

Cross-reference numbers can help identify a replacement, but full technical compatibility should always be checked before installation.

Why 64x80 mm Dimensions Are Not Enough

Many rotary shaft seals are available with basic dimensions of:

64x80 mm

However, seals with identical inside and outside diameters may differ in:

• width
• stepped axial dimensions
• material
• seal profile
• sealing-lip geometry
• dust lip
• application
• installation arrangement

For CORTECO 01026493, the complete dimensions are:

64x80x11.5/16 mm

and the construction is:

NBR BASLX7

These parameters should be considered together when identifying an equivalent seal.

How to Select a Replacement for CORTECO 01026493

Before selecting an alternative, compare:

1. CORTECO reference
2. Mercedes-Benz OE reference
3. 64 mm inside diameter
4. 80 mm outside diameter
5. 11.5/16 mm axial dimensions
6. BASLX7 construction
7. NBR material
8. additional dust lip
9. installation geometry
10. exact axle or steering knuckle application

The most reliable identification combines:

CORTECO 01026493 + Mercedes-Benz 0229970047 + 64x80x11.5/16 + NBR BASLX7

CORTECO 01026493 vs Generic 64x80 Oil Seal

A generic 64x80 oil seal should not automatically be considered a replacement for CORTECO 01026493.

The CORTECO seal has a specific:

• BASLX7 profile
• 11.5/16 mm axial geometry
• NBR material
• dust-lip arrangement
• automotive application

Even if the main diameters are identical, differences in these parameters can prevent correct installation or sealing performance.

Is ELRING 008.592 a Cross Reference?

Yes. ELRING 008.592 is listed in aftermarket catalogues as a cross-reference associated with this application.

Full specifications should still be compared before using an alternative product.

Is FEBI BILSTEIN 26286 a Cross Reference?

Yes. FEBI BILSTEIN 26286 is also found in aftermarket cross-reference data associated with CORTECO 01026493 / 01026493B.

Verify dimensions, construction and the Mercedes-Benz OE reference before replacement.

Technical Specification

Common Selection Mistakes

Common mistakes when selecting this seal include:

• selecting only by the 64x80 mm diameters
• ignoring the 11.5/16 mm axial dimensions
• overlooking the BASLX7 construction
• ignoring the NBR material
• overlooking the additional dust lip
• assuming every 64x80 oil seal is interchangeable
• failing to verify the Mercedes-Benz OE number
• ignoring the exact axle or steering knuckle configuration

For automotive applications, exact fitment should always be confirmed before installation.
