The IVECO OE references support component identification in vehicle parts documentation.

Their presence in replacement-parts catalogues does not automatically establish compatibility with every IVECO vehicle model.

What does CORTECO 12011041 NBR BA 88x126x12 mean?

The designation identifies the manufacturer, catalogue reference, elastomer material, sealing profile and nominal dimensions.

• CORTECO - manufacturer brand.

• 12011041 - base catalogue reference.

• NBR - nitrile butadiene rubber.

• BA - conventional radial shaft sealing profile.

• 88 mm - nominal shaft diameter.

• 126 mm - nominal housing bore diameter.

• 12 mm - nominal axial width.

Nominal dimensions do not specify shaft or housing bore manufacturing tolerances.

These must be determined according to the technical requirements of the mechanical assembly.

BA sealing profile - construction and operating principle

1. Primary sealing lip

The BA profile incorporates a primary sealing lip operating against the rotating shaft surface.

Its function is to limit lubricant leakage from the sealed mechanical assembly.

Correct sealing performance depends on shaft surface quality, lubrication and compatibility between the elastomer and the operating medium.

2. Garter spring

A conventional BA radial shaft seal typically incorporates a circumferential garter spring.

The spring helps maintain contact pressure between the sealing lip and the shaft surface.

Detailed spring specifications for CORTECO 12011041 have not been confirmed in the available catalogue information.

3. Elastomer-covered outer surface

The standard BA construction typically features an elastomer-covered outer surface and an internal reinforcing element.

The outer elastomer covering provides static sealing between the seal body and the housing bore.

Correct installation fit and housing surface condition are important for maintaining sealing performance.

4. Additional dust lip

An additional dust lip is not a standard feature of the BA sealing profile.

BA should not be confused with BASL, which incorporates an additional dust lip for contamination protection.

NBR - technical material properties

NBR is a technical elastomer widely used in rotating shaft sealing applications.

Appropriately selected NBR compounds typically offer:

• Good resistance to many mineral oils.

• Compatibility with numerous industrial greases.

• Useful mechanical properties.

• Suitability for oil-lubricated mechanical assemblies.

• Applicability in appropriately specified mechanical drive systems.

Temperature and chemical resistance depend on the specific NBR compound and operating conditions.

Individual maximum values for operating temperature, pressure and peripheral shaft speed have not been confirmed for CORTECO 12011041.

BA versus BASL - sealing profile comparison

Changing the sealing profile may affect lip contact conditions and friction.

Matching dimensions alone do not guarantee interchangeability.

CORTECO 12011041 applications in IVECO vehicles

The CORTECO dimensional catalogue associates part number 12011041 with IVECO.

Replacement-parts catalogues classify reference 12011041B as a shaft seal associated with a drive axle or differential assembly.

A historical dimensional listing also references the IVECO/FIAT 682 N3/T3 and N4/T4 vehicle families.

This catalogue association must be verified against the documentation for the specific vehicle.

Before ordering, check:

• Original equipment part number.

• Vehicle model and version.

• Axle or mechanical assembly type.

• Installation position.

• Seal dimensions and construction.

CORTECO 12011041 should not be considered a universal seal for all IVECO drive axles.

Comparison with other CORTECO radial shaft seals

The CORTECO dimensional catalogue also lists seals with a nominal inner diameter of 88 mm.

This comparison illustrates dimensional and construction differences rather than confirmed replacement alternatives.

None of the listed variants should automatically be used as a substitute for CORTECO 12011041.

Selection and interchangeability

Before ordering CORTECO 12011041, verify:

1. Nominal shaft diameter - 88 mm.

2. Nominal housing bore diameter - 126 mm.

3. Installation width - 12 mm.

4. NBR elastomer material.

5. BA sealing profile.

6. Requirements for an additional dust lip.

7. Type of oil or grease.

8. Operating temperature and shaft rotational speed.

9. Condition of the shaft and housing surfaces.

10. OE reference and installation position in the IVECO parts documentation.

Matching the OE reference is an important part of identification, but the sealing construction and operating requirements must also be confirmed.

Alternative designations and reference numbers

Common product identification variants include:

• CORTECO 12011041

• CORTECO 12011041B

• CORTECO 82011041

• CORTECO NBR BA 88x126x12

• CORTECO 88x126x12 NBR Oil Seal

• CORTECO 12011041 Radial Shaft Seal

• CORTECO 88x126x12 Rotary Shaft Seal

• CORTECO BA 88x126x12 Shaft Seal

• IVECO 886807

• IVECO 40001300

• IVECO 40001304

The IVECO numbers are OE references listed in replacement-parts catalogues, not additional CORTECO catalogue numbers.

Installation and operating recommendations

Before installation, thoroughly clean the housing bore and shaft surface.

Inspect the shaft for scratches, corrosion, wear grooves and sharp edges that could damage the sealing lip.

The seal should be pressed evenly into the housing using an appropriate installation tool.

Installation force should not be applied directly to the working lip.

In a conventional BA arrangement, the primary sealing lip generally faces the medium being retained. However, the correct orientation must be confirmed using the documentation for the specific axle or differential assembly.

Before installation, store the seal in a clean, dry environment protected from mechanical damage and excessive heat.
