CORTECO 12011020 NBR BA 75x95x10 mm Radial Shaft Seal

Technical specifications

Unconfirmed operating temperature limits, pressure ratings, peripheral shaft speeds and NBR compound hardness values should not be assigned to this product.

What does CORTECO 12011020 NBR BA 75x95x10 mean?

The designation contains the essential information required to identify the seal.

• CORTECO - manufacturer brand.

• 12011020 - product catalogue reference.

• NBR - nitrile butadiene rubber.

• BA - conventional radial shaft sealing profile.

• 75 mm - nominal shaft diameter.

• 95 mm - nominal housing bore diameter.

• 10 mm - nominal axial width.

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

Installation fits must be determined according to the design requirements of the sealed mechanical assembly.

OE numbers and cross-reference numbers

The following references are used to identify the product in replacement-parts catalogues.

Reference 392787X1 is associated with both LANDINI and MASSEY FERGUSON.

The MERCEDES-BENZ reference 9975646 may appear in catalogues with additional leading zeros. The complete designation should be checked against the vehicle manufacturer's documentation.

ELRING 528102 is a comparative replacement-parts reference rather than an equipment manufacturer's OE number.

Important: Cross-reference compatibility should be confirmed using the current parts catalogue for the specific machine. The presence of a reference in an interchange list does not guarantee compatibility with every vehicle or mechanical assembly.

CORTECO 12011020 - sealing construction

1. Primary sealing lip

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

Its function is to limit the leakage of oil or another compatible medium from the sealed mechanical assembly.

Correct operation depends on shaft surface geometry, lubrication and operating conditions.

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.

It supports stable sealing contact during operation.

Detailed spring specifications for CORTECO 12011020 have not been established from the supplied product 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 housing surface condition and installation fit are essential for maintaining sealing performance.

4. Additional dust lip

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

If the mechanical assembly requires additional protection against external contamination, the original specification should be checked to determine whether another profile, such as BASL, is required.

NBR - technical material properties

NBR, or nitrile butadiene rubber, is an elastomer commonly used in radial shaft sealing applications.

Appropriately selected NBR compounds typically provide:

• Good resistance to many mineral oils.

• Compatibility with numerous industrial greases.

• Useful mechanical properties.

• Suitability for rotating shaft sealing.

• Resistance to many conventional lubricants used in mechanical drive assemblies.

Compatibility depends on the specific oil, its additives, operating temperature and elastomer compound.

NBR is not universally resistant to all chemicals or operating temperatures.

Individual maximum values for operating temperature, pressure and peripheral shaft speed have not been confirmed for CORTECO 12011020.

BA versus BASL - construction differences

Using a different sealing profile may change shaft contact conditions, friction and installation requirements.

BA and BASL should not automatically be considered interchangeable based solely on nominal dimensions.

Applications of CORTECO 12011020

The listed reference numbers associate this product with replacement-parts catalogues for agricultural machinery and commercial vehicles.

JOHN DEERE, LANDINI, MASSEY FERGUSON and SAME

References AL38358, 392787X1 and 215100390 help identify corresponding parts in the equipment manufacturers' catalogues.

However, a single common installation position or a specific model compatibility list has not been confirmed for all these references.

MERCEDES-BENZ and RENAULT TRUCKS

References 9975646 and 5010216049 indicate catalogue associations with commercial vehicle applications.

Before installation, the OE reference, installation position and original seal construction must be verified.

The listed manufacturers and reference numbers support part identification. They do not guarantee compatibility with every vehicle produced by those manufacturers.

Selection and interchangeability

Before ordering CORTECO 12011020, verify:

1. Nominal shaft diameter - 75 mm.

2. Nominal housing bore diameter - 95 mm.

3. Installation width - 10 mm.

4. NBR elastomer material.

5. BA sealing profile.

6. Requirements for an additional dust lip.

7. Type of oil, grease or other operating medium.

8. Operating temperature and shaft rotational speed.

9. Condition of the shaft and housing surfaces.

10. OE reference and installation position in the equipment documentation.

Identical dimensions of 75x95x10 mm do not guarantee full technical interchangeability.

Radial shaft seals may differ in material, number of sealing lips, outer surface construction or permissible operating conditions.

Alternative designations and reference numbers

These references support product identification but do not independently establish complete interchangeability.

Installation and operating recommendations

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

Particular attention should be paid to 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 must 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 mechanical assembly.

Surface preparation and lubrication during installation should follow the equipment manufacturer's recommendations.
