CORTECO 12014852B NBR RWDR-K7 155x190x17.5/19 mm is a cassette-type rotary shaft seal with a 155 mm inside diameter, 190 mm outside diameter and two relevant axial dimensions of 17.5/19 mm. The RWDR-K7 designation identifies the cassette construction, so replacement selection should consider the complete profile, NBR elastomer and both axial dimensions rather than dimensions alone. Trade No. 82014852, EAN 3358960148520. Also searched as CORTECO 12014852, RWDR-K7 155x190x17.5/19 and 155x190x17.5/19 cassette seal.
CORTECO 12014852B is an NBR cassette-type rotary shaft seal with the RWDR-K7 profile and dimensions 155x190x17.5/19 mm. The nominal inside diameter is 155 mm, the outside diameter is 190 mm, while the cassette design has two relevant axial dimensions: 17.5 and 19 mm. The complete identification 12014852B / NBR / RWDR-K7 / 155x190x17.5/19 mm is important because this is a cassette sealing system rather than a conventional radial shaft seal identified only by three basic dimensions.
CORTECO 12014852B belongs to the group of cassette seals designed for rotary shaft sealing arrangements.
Confirmed identification data:
The most precise product identification combines the reference 12014852B with the RWDR-K7 profile, NBR elastomer and the complete 155x190x17.5/19 mm dimensions.
The principal dimensional data are:
| Parameter | Value |
|---|---|
| Inside diameter | 155 mm |
| Outside diameter | 190 mm |
| Axial dimension 1 | 17.5 mm |
| Axial dimension 2 | 19 mm |
| Complete dimensions | 155x190x17.5/19 mm |
For this specific reference, it is important to retain the complete dimensional notation:
155x190x17.5/19 mm
The dimensions should not be simplified to 155x190x17.5 mm or 155x190x19 mm, because 17.5/19 describes the axial geometry of this particular cassette seal design.
CORTECO identifies this product with the profile:
RWDR-K7
This is a cassette-type rotary shaft sealing construction. Compared with a conventional radial shaft seal, a cassette seal is a more integrated sealing system.
Cassette sealing systems combine several functional elements within one assembly. Depending on the exact design, the sealing elements and their running surface can form part of the integrated sealing unit, creating a controlled sealing interface rather than relying solely on the existing shaft surface.
This construction also provides a more complex barrier between the lubricated side of the assembly and the external environment than a basic single radial sealing element.
For CORTECO 12014852B, the exact designation RWDR-K7 should therefore be retained when identifying or replacing the product.
It should not automatically be considered equivalent to every product described generically as a cassette seal, combi seal or RWDR seal.
CORTECO 12014852B uses NBR – nitrile butadiene rubber as its elastomer material.
NBR is widely used in rotary sealing technology because of its compatibility with many mineral oils and lubricating greases.
However, NBR is not universally compatible with every fluid, chemical additive or operating temperature.
When selecting this seal for a particular assembly, the actual lubricant or medium, operating temperature, rotational conditions and other environmental factors should be considered.
No arbitrary maximum temperature, pressure, shaft speed or NBR hardness is assigned to CORTECO 12014852B here because these parameters have not been confirmed for the exact application.
A cassette seal differs from a conventional radial shaft seal because it forms an integrated sealing system rather than relying on one basic sealing interface.
The system is designed to separate the lubricated internal area from the external environment while also restricting the ingress of external contamination.
Cassette-type designs can use several sealing elements and sealing paths to create a more complex contamination barrier than a conventional basic rotary shaft seal.
This construction is particularly relevant in rotating assemblies where the sealing position is exposed to external contamination.
The exact effectiveness of the sealing system still depends on correct installation, mating-component geometry and the operating conditions of the complete assembly.
12014852B is the CORTECO catalogue reference identifying the exact product.
The base reference:

is also associated with this product.
82014852 is a trade number associated with CORTECO 12014852B.
NBR identifies nitrile butadiene rubber as the elastomer material.
RWDR-K7 is the construction/profile designation for this cassette sealing system.
The RWDR-K7 designation should be retained when selecting a replacement rather than reducing the identification simply to “155x190 cassette seal”.
The complete dimensional identification is:
155x190x17.5/19 mm
Both axial dimensions, 17.5 and 19 mm, are part of the product identification and should be retained in technical documentation, enquiries and replacement searches.
The most precise starting point for product selection is the complete reference:
CORTECO 12014852B
combined with:
NBR / RWDR-K7 / 155x190x17.5/19 mm
If the reference on the original seal is unreadable, selection should include verification of:
Both 17.5 and 19 mm should be considered during dimensional verification.
Industry catalogues associate CORTECO 12014852B with several additional references, including:
82014852
DANA 001251544
DANA 1251544
DANA 1230601601
These numbers can be useful when researching an existing sealing arrangement, but they should not automatically be interpreted as proof of unconditional interchangeability in every application.
Before installation, verify the OEM reference for the exact assembly, complete dimensions, cassette construction, elastomer, profile and mounting requirements.
No.
Identical principal dimensions do not automatically mean identical sealing construction.
Two products described as 155x190x17.5/19 mm cassette seals can differ in:
A replacement for CORTECO 12014852B should therefore be selected using the complete technical specification rather than dimensions alone.

It is a cassette-type rotary shaft seal with the CORTECO profile designation RWDR-K7.
The elastomer material is NBR – nitrile butadiene rubber.
RWDR-K7 is the construction/profile designation associated with this CORTECO cassette seal. It should be retained when identifying a replacement rather than selecting solely by dimensions.
The complete dimensional identification should remain 155x190x17.5/19 mm. Omitting the 19 mm value removes relevant information about the axial geometry.
Yes. 82014852 is a trade number associated with CORTECO 12014852B.
Industry catalogue data associate DANA 001251544 with CORTECO 12014852B. Compatibility should still be confirmed against the exact OEM assembly, dimensions, seal construction and installation requirements.
No. Matching dimensions alone do not establish full interchangeability. The RWDR-K7 profile, NBR material, cassette construction and mounting requirements should also be verified.
CORTECO 12014852B is an NBR RWDR-K7 cassette-type rotary shaft seal with dimensions 155x190x17.5/19 mm. Its cassette construction forms an integrated sealing system between the lubricated assembly and external environment. Correct replacement requires verification of the complete reference, RWDR-K7 profile, NBR elastomer and both 17.5/19 mm axial dimensions.
