CORTECO 12018030 45x65x25 NBR RWDR-KOMBI Rotary Shaft Seal

CORTECO 12018030 45x65x25 NBR RWDR-KOMBI Rotary Shaft Seal

CORTECO 12018030 is an NBR rotary shaft seal with RWDR-KOMBI construction, measuring 45x65x25 mm. Its confirmed dimensions are 45 mm inside diameter, 65 mm outside diameter and 25 mm axial height. The RWDR-KOMBI design is a key part of this exact product identification; related catalogue references include 12018030B and trade/product number 82018030.

Exact identification:

CORTECO 12018030 – 12018030B – 82018030 – 45x65x25 mm – NBR – RWDR-KOMBI

CORTECO 12018030 RWDR-KOMBI – Technical Characteristics

The defining feature of this reference, in addition to its dimensions, is the:

RWDR-KOMBI

construction.

The Corteco catalogue identifies exact reference 12018030 as:

NBR – RWDR-KOMBI – 45x65x25 mm.

This means that product selection should not be based solely on the dimensional notation 45x65x25 mm.

The RWDR-KOMBI design forms part of the complete technical identification of the seal and should be retained when ordering or cross-referencing the product.

CORTECO 12018030 Dimensions

Catalogue data for the related 12018030B reference identify these parameters as:

Inside Diameter = 45 mm

Outside Diameter = 65 mm

Height = 25 mm.

The technically safe dimensional notation for this reference is therefore:

45x65x25 mm.

The third dimension should not automatically be labelled B when the available exact-reference catalogue data define it as height.

RWDR-KOMBI Construction

CORTECO 12018030 should not be treated as a conventional radial shaft seal identified only by three basic dimensions.

Its catalogue designation:

RWDR-KOMBI

identifies a combined sealing construction.

When comparing this reference with another rotary shaft seal, the complete sealing geometry and construction must therefore be considered in addition to the shaft and housing diameters.

Individual functional details of the RWDR-KOMBI design should not be assumed beyond what is confirmed for exact reference 12018030.

NBR Material

The confirmed elastomer for CORTECO 12018030 is:

NBR – acrylonitrile-butadiene rubber, commonly known as nitrile rubber.

For exact product identification, the important combination is:

12018030 + NBR + RWDR-KOMBI + 45x65x25 mm.

An exact maximum operating temperature, shaft speed, surface speed or permissible pressure should not be assigned to this specific reference merely from generic NBR material properties.

12018030, 12018030B and 82018030

Several directly related identifiers may appear when searching for this seal.

12018030 – reference appearing in the Corteco dimensional catalogue.

12018030B – related Corteco/TecDoc reference.

82018030 – associated Corteco trade/product number.

Catalogue data for 12018030B also identify:

RWDR-KOMBI

and the trade/product number:

82018030.

The EAN associated with 12018030B is:

3358960144461.

When ordering, the complete reference shown on the product, packaging or supplier documentation should be retained.

RWDR-KOMBI vs Standard 45x65x25 Oil Seal

Dimensions alone are insufficient to establish interchangeability.

A seal measuring:

45x65x25 mm

but using a different construction should not automatically be considered equivalent to:

CORTECO 12018030 NBR RWDR-KOMBI.

A replacement comparison should include:

45 mm inside diameter

65 mm outside diameter

25 mm axial dimension

NBR material

RWDR-KOMBI construction

and:

exact catalogue reference.

This distinction is particularly important where different seal profiles share the same nominal installation dimensions.

Application of CORTECO 12018030

The Corteco catalogue associates exact reference:

12018030 NBR RWDR-KOMBI 45x65x25

with:

MASSEY FERGUSON.

Catalogue data for the related 12018030B reference classify the product as a:

differential shaft seal

and indicate the installation context:

drive axle.

These application data are useful for product identification, but they should not replace verification of the OE reference for a particular machine, axle or production version.

OE References Associated with CORTECO 12018030

Catalogue data associate 12018030B with OE references including:

CARRARO 142652

DANA 3765756M1

DANA 7600100501

HÜRLIMANN 215291590

JOHN DEERE L156857

LAMBORGHINI 215291590

MASSEY FERGUSON 3765756M1

and:

SAME 215291590.

These OE numbers are useful when identifying the seal in agricultural machinery and axle/driveline assemblies.

Compatibility should still be verified for the exact machine model and version before installation.

Selection and Interchangeability

When selecting an equivalent for CORTECO 12018030, compare:

reference – 12018030 / 12018030B

trade/product number – 82018030

inside diameter – 45 mm

outside diameter – 65 mm

axial height – 25 mm

material – NBR

construction – RWDR-KOMBI

sealing geometry

and, when selecting for a specific machine:

OE reference.

The generic description:

45x65x25 NBR oil seal

does not by itself establish full interchangeability.

RWDR-KOMBI.

A conventional radial shaft seal with the same 45 mm inside diameter and 65 mm outside diameter may use a fundamentally different sealing arrangement.

Is 12018030 the Same as 12018030B?

The references are directly related in catalogue data.

12018030 appears in the Corteco dimensional catalogue, while 12018030B is also used in current catalogue/TecDoc data.

The associated trade/product number is:

82018030.

When ordering, retain the complete reference stated on the product or supplier documentation rather than automatically adding or removing the B suffix.

Can a Standard 45x65x25 Seal Replace CORTECO 12018030?

Interchangeability cannot be established from dimensions alone.

A potential replacement should be checked for:

45 mm inside diameter

65 mm outside diameter

25 mm axial height

NBR material

RWDR-KOMBI construction

sealing geometry

and:

catalogue/OE compatibility.
