Technical Specifications

The exact operating temperature range, maximum shaft speed, permissible pressure and elastomer hardness require confirmation from product-specific technical documentation.

OE Reference Numbers - Alfa Romeo, Iveco and Scania

CORTECO 12010887 is associated with the following original equipment reference numbers.

These OE numbers are cross-reference identifiers used to compare replacement parts.

An OE reference does not guarantee compatibility with every vehicle produced by the corresponding manufacturer.

Before ordering, verify the original part number, seal dimensions, profile and vehicle-specific requirements. VIN-based verification is recommended where available.

Alfa Romeo Applications

CORTECO 12010887B is listed in replacement parts catalogues for selected versions of:

• Alfa Romeo Giulia.

• Alfa Romeo Giulia GT.

Compatibility depends on the vehicle version, production year and wheel hub assembly.

For Iveco and Scania vehicles, the original equipment reference number and vehicle documentation should be used to confirm fitment.

What Does CORTECO 12010887 NBR BA 30x52x10 Mean?

The product designation identifies the manufacturer, catalogue reference, material, profile and dimensions.

CORTECO - manufacturer and brand of the sealing component.

12010887 - product reference number.

NBR - Nitrile Butadiene Rubber, an elastomer commonly used for oil sealing.

BA - a radial shaft seal profile with a rubber-covered outer case and a spring-loaded primary sealing lip.

30x52x10 mm - nominal inside diameter, outside diameter and width.

BA Rotary Shaft Seal Construction

Primary Sealing Lip

The primary sealing lip contacts the rotating shaft and provides the main sealing function.

It helps reduce lubricant leakage from the mechanical assembly.

Garter Spring

The circumferential garter spring helps maintain sealing lip contact with the shaft surface during operation.

Rubber-Covered Outer Case

The internal metal reinforcement provides structural rigidity.

The rubber-covered outside diameter forms the sealing interface between the seal and housing bore.

Correct housing dimensions, surface finish and installation are important for reliable performance.

BA vs BASL Seal Profiles

In commonly used rotary shaft seal terminology:

A BA seal should not automatically be replaced with a BASL or TC seal, even when the dimensions are identical.

NBR Sealing Material

NBR is widely used in automotive and industrial rotary shaft seals.

Typical material characteristics include:

• Good resistance to many mineral oils.

• Compatibility with many mineral-based greases.

• Good mechanical properties for conventional sealing applications.

• Suitability for various oil-lubricated mechanical assemblies.

Chemical compatibility depends on the specific NBR compound, lubricant and operating conditions.

NBR is not universally resistant to all fuels, solvents or high-temperature environments.

A specific operating temperature range should not be assumed without verified manufacturer specifications.

Wheel Hub Oil Seal - Function and Applications

In a correctly designed wheel hub assembly, an oil seal helps retain lubricant within the mechanism.

Proper sealing contributes to maintaining suitable lubrication conditions for the associated mechanical components.

Sealing performance depends on several factors:

• Shaft surface condition.

• Housing bore dimensions.

• Correct seal material.

• Sealing lip design.

• Operating conditions.

• Installation accuracy.

CORTECO 12010887 may also be used in other suitable rotary shaft assemblies when the dimensions, profile and material meet the equipment manufacturer's requirements.

How to Select the Correct CORTECO 12010887 Seal

Before ordering, verify:

1. CORTECO reference 12010887 or 12010887B.

2. Original equipment reference number.

3. Shaft diameter - 30 mm.

4. Housing bore diameter - 52 mm.

5. Seal width - 10 mm.

6. NBR sealing material.

7. BA sealing profile.

8. Spring-loaded primary sealing lip.

9. Rubber-covered outer case.

10. Equipment-specific installation requirements.

Identical dimensions do not guarantee interchangeability.

Rotary shaft seals with the same dimensions may differ in sealing lip construction, elastomer material and outer-case design.

Installation Guidelines

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

Check for:

• Shaft wear grooves.

• Scratches and corrosion.

• Sharp edges.

• Contamination.

• Incorrect housing dimensions.

• Excessive shaft runout or bearing play.

Install the seal squarely using a suitable installation tool.

Apply installation force evenly without deforming the seal case or damaging the sealing lip.

In conventional oil-retention applications, the spring-loaded primary lip normally faces the lubricant. Always follow the equipment manufacturer's installation instructions.

Frequently Asked Questions

What are the dimensions of CORTECO 12010887?

The nominal dimensions are 30x52x10 mm: 30 mm inside diameter, 52 mm outside diameter and 10 mm width.

What does the BA profile mean?

BA identifies a rotary shaft seal design with a rubber-covered outer case and a spring-loaded primary sealing lip.

Is CORTECO 12010887 a double-lip oil seal?

The standard BA profile does not include an additional dust lip. It should not be confused with BASL or TC double-lip profiles.

Are CORTECO 12010887 and 12010887B related references?

Yes. These references are associated with the CORTECO NBR BA 30x52x10 mm rotary shaft seal. The commercial reference 82010887 is also used.

Does this oil seal fit Alfa Romeo vehicles?

The listed Alfa Romeo OE references include 2340343640, 234034364C, 60751052 and 60751055. Fitment must be verified for the specific vehicle.

What is the Scania OE reference?

The listed Scania OE reference is 139038.

What material is used?

The sealing element is manufactured from NBR, or Nitrile Butadiene Rubber.

Can a 30x52x10 TC oil seal replace this BA seal?

Not automatically. TC seals typically include an additional dust lip. Construction and installation requirements must be checked before substitution.

Is this seal suitable for oil?

NBR is commonly used with many mineral oils and greases. Compatibility with the specific lubricant and operating conditions should be verified.
