CORTECO 12012583 NBR BAOF 8x12x3 mm - Radial Shaft Seal Ducati

CORTECO 12012583 NBR BAOF 8x12x3 mm - Radial Shaft Seal Ducati

CORTECO 12012583 NBR BAOF 8x12x3 mm is a radial rotary shaft seal manufactured from NBR nitrile rubber with the CORTECO BAOF profile. The product is also catalogued as CORTECO 12012583B, trade number 82012583. Its nominal dimensions are 8 mm inside diameter, 12 mm outside diameter and 3 mm width. The confirmed Ducati OE reference is 937830812.

CORTECO 12012583 - Technical Data

What Does CORTECO 12012583 NBR BAOF Mean?

The complete product identification is:

CORTECO 12012583 NBR BAOF 8x12x3 mm

The individual elements identify the specific seal:

CORTECO - manufacturer and brand.

12012583 - base product reference.

12012583B - reference found in current parts catalogues.

82012583 - CORTECO trade number.

NBR - nitrile rubber used as the elastomer material.

BAOF - CORTECO profile designation.

8x12x3 mm - nominal seal dimensions.

The BAOF profile is an important part of the technical identification. A different NBR shaft seal measuring 8x12x3 mm should not automatically be considered identical or interchangeable.

CORTECO 12012583 Dimensions

The nominal dimensions are:

8x12x3 mm

where:

8 mm - inside diameter

12 mm - outside diameter

3 mm - width

Because this is a very small shaft seal, accurate verification of all three dimensions is particularly important.

The complete dimensional designation should be retained as:

8x12x3 mm

NBR - Nitrile Rubber

CORTECO 12012583B is manufactured from NBR nitrile rubber.

NBR is widely used in technical sealing applications, particularly in appropriately selected systems involving oils, lubricants and other media compatible with the particular nitrile rubber compound.

However, an exact maximum operating temperature, pressure or shaft speed should not be assigned to this specific seal solely on the basis of general NBR properties.

Actual operating limits depend on factors including the specific elastomer compound, operating medium, temperature, shaft surface speed, mating-surface condition, lubrication and the design of the complete sealing system.

CORTECO BAOF Profile

BAOF is the CORTECO profile designation assigned to this specific product.

The profile should be treated as an important identification parameter together with:

12012583 / 12012583B

NBR

8x12x3 mm

The individual characters of BAOF should not be interpreted according to the nomenclature of an unrelated seal manufacturer. Profile designation systems can be manufacturer-specific.

When selecting an alternative seal, the complete construction should therefore be compared rather than relying on dimensions alone.

Ducati OE 937830812

The confirmed OE reference associated with CORTECO 12012583B is:

DUCATI 937830812

This OE number is an important identification criterion for corresponding Ducati applications.

It does not mean that CORTECO 12012583B fits every Ducati motorcycle or mechanical assembly.

When selecting the seal for a specific motorcycle, verify that the relevant Ducati parts documentation specifies OE reference:

937830812

CORTECO 12012583 vs Other 8x12 mm Shaft Seals

The 8 mm inside diameter and 12 mm outside diameter alone are not sufficient to uniquely identify the product.

Other seals with the same principal dimensions may differ in:

width

elastomer material

profile

sealing-lip geometry

outside surface construction

intended application

OE reference

For this product, the complete identification should be retained:

CORTECO 12012583 / 12012583B

NBR

BAOF

8x12x3 mm

DUCATI 937830812

Is Every 8x12x3 mm Shaft Seal Interchangeable?

No.

Identical nominal dimensions confirm only basic geometric compatibility.

Another 8x12x3 mm shaft seal may differ in:

elastomer material

profile construction

sealing-lip geometry

outside diameter construction

intended operating conditions

application

OE reference

CORTECO 12012583 should therefore not automatically be replaced by any other 8x12x3 mm seal solely because the dimensions match.

How to Select CORTECO 12012583

Before ordering, verify:

• CORTECO reference 12012583 or 12012583B,
• trade number 82012583,
• dimensions 8x12x3 mm,
• inside diameter 8 mm,
• outside diameter 12 mm,
• width 3 mm,
• NBR material,
• BAOF profile,
• Ducati OE reference 937830812,
• compatibility with the specific motorcycle or mechanical assembly.

When selecting the seal for a Ducati motorcycle, the OE reference should be checked against the exact model and application.

Construction and Operating Principle

CORTECO 12012583B is a compact radial shaft seal designed for operation in an appropriately specified assembly with a rotating shaft.

The sealing element operates against the shaft surface, while the outside section is located in the stationary housing.

Correct sealing performance depends not only on the seal itself but also on factors including:

shaft surface condition

alignment

housing geometry

operating medium

lubrication conditions

temperature

shaft surface speed

Because of the very small dimensions of this seal, particular care should be taken to prevent damage or deformation during installation.

Installation of CORTECO 12012583

Before installation, thoroughly clean the shaft and seal housing.

Check the mating surface for corrosion, burrs, sharp edges, scratches and excessive wear.

Install the seal evenly and without tilting, using a suitable installation tool appropriate for its small dimensions.

The installation tool should not deform or damage the seal profile.

If the sealing element must pass over threads, grooves or sharp edges, protect it against cutting or mechanical damage.

The correct installation orientation should also be confirmed before assembly.

Storage

Store the seal in clean, dry conditions, preferably in its original packaging.

Protect NBR components from direct sunlight, excessive heat and substances that could damage the elastomer.

Avoid mechanical deformation of the seal during storage.
