CORTECO 01034873 30x52x12 NBR B1 Rotary Shaft Seal

CORTECO 01034873 30x52x12 NBR B1 Rotary Shaft Seal

CORTECO 01034873 is a radial shaft seal / rotary shaft seal / oil seal with nominal dimensions of 30x52x12 mm, manufactured from NBR - Nitrile Butadiene Rubber. The CORTECO dimensional catalogue identifies its construction profile as B1. The product is also referenced as 01034873B.

Complete technical identification:

CORTECO + 01034873 + 30x52x12 mm + NBR + B1

CORTECO 01034873 - Technical Characteristics

The confirmed catalogue identification data are:

Manufacturer: CORTECO

Part number: 01034873

Additional reference: 01034873B

Product type: Radial shaft seal / rotary shaft seal / oil seal

Dimensions: 30x52x12 mm

Inside diameter d: 30 mm

Outside diameter D: 52 mm

Height H: 12 mm

Material: NBR

Material name: Nitrile Butadiene Rubber

CORTECO catalogue profile: B1

EAN: 3358960489043

The CORTECO dimensional catalogue identifies the exact combination as:

01034873 | NBR | B1 | 30 | 52 | 12

A second technical catalogue using the reference with a final B identifies:

01034873B | B1 | 30 | 52 | 12 | NBR

The preferred technical identification is therefore:

01034873 + 30x52x12 + NBR + B1

CORTECO 01034873 Dimensions

The nominal installation dimensions are:

d = 30 mm - nominal inside / shaft diameter

D = 52 mm - nominal outside diameter / corresponding housing bore diameter

H = 12 mm - nominal height

Complete dimensions:

30x52x12 mm

All three dimensions should be retained when identifying or selecting the product.

The abbreviated size:

30x52 mm

is not sufficient because CORTECO catalogue data contain multiple shaft seals with these principal diameters and different heights, materials or construction profiles.

NBR - Nitrile Butadiene Rubber

The sealing material specified for CORTECO 01034873 is:

NBR - Nitrile Butadiene Rubber

Material forms an integral part of the exact technical identification:

01034873 + NBR + B1

A 30x52x12 mm shaft seal manufactured from FPM or another elastomer should not automatically be considered the same technical variant.

The exact NBR compound used for CORTECO 01034873 has not been confirmed in the available product-specific documentation. Therefore, a fixed Shore hardness, operating temperature range or chemical compatibility should not be assigned solely from generic NBR properties.

CORTECO B1 Seal Profile

The exact profile stated in the verified CORTECO dimensional catalogue for 01034873 is:

B1

This designation should be retained when identifying, ordering or comparing the product.

It should not automatically be converted to:

BA

BASL

SC

TC

AO/TC

or another manufacturer's profile designation.

The exact catalogue identification remains:

CORTECO 01034873 + NBR + B1

B1 vs B1FUD2 - Important Catalogue Difference

A discrepancy exists between the verified dimensional catalogues and some current distributor listings.

The CORTECO dimensional catalogue identifies:

01034873 - NBR - B1 - 30x52x12

A second technical catalogue identifies:

01034873B - B1 - 30x52x12 - NBR

However, some aftermarket databases and distributor listings describe 01034873 / 01034873B using:

B1FUD2

For this product description, B1 is retained as the primary profile because it is explicitly stated in the verified dimensional catalogue.

B1 and B1FUD2 should not be merged or treated as automatically identical without additional CORTECO documentation explaining the relationship between these designations.

CORTECO 01034873 vs 01034873B

Two reference forms can be encountered:

01034873

and:

01034873B

Technical catalogue data associated with these references agree on the core specification:

30x52x12 mm

NBR

B1

Therefore, 01034873B is useful as an additional searchable reference, while the main product identification can remain:

CORTECO 01034873

EAN 3358960489043

The EAN associated with CORTECO 01034873 / 01034873B in distributor catalogue data is:

3358960489043

This provides an additional commercial identifier when searching inventory and aftermarket databases.

For technical identification, however, the most important combination remains:

CORTECO + 01034873 + 30x52x12 + NBR + B1

CORTECO 01034873 vs Other 30x52 Shaft Seals

CORTECO catalogue data contain multiple shaft seals with principal diameters of:

30x52 mm

Examples include:

CORTECO 12011135 - 30x52x7 NBR BASL

CORTECO 01033894 - 30x52x9 NBR B2

CORTECO 12010887 - 30x52x10 NBR BA

CORTECO 01034873 - 30x52x12 NBR B1

CORTECO 12002492 - 30x52x12 NBR B1

This demonstrates that searching only for:

30x52 oil seal

does not uniquely identify CORTECO 01034873.

The final example is particularly important because 01034873 and 12002492 share the same nominal dimensions, NBR material and B1 catalogue profile but remain separate CORTECO references.

CORTECO 01034873 vs 12002492

According to the dimensional catalogue:

CORTECO 01034873

Dimensions: 30x52x12 mm

Material: NBR

Profile: B1

and:

CORTECO 12002492

Dimensions: 30x52x12 mm

Material: NBR

Profile: B1

The catalogue additionally associates 12002492 with DEUTZ, while no equivalent application entry is stated for 01034873 in the same table.

For this reason, the two part numbers should not automatically be declared interchangeable solely because the dimensional, material and basic profile data match.

The original CORTECO reference should always be checked.

How Does CORTECO 01034873 Work?

CORTECO 01034873 is installed between a rotating shaft and a stationary housing.

The nominal:

d = 30 mm

corresponds to the shaft-side installation dimension.

The nominal:

D = 52 mm

defines the outside diameter of the seal and corresponding housing bore dimension.

The:

H = 12 mm

value specifies the nominal axial height.

The sealing element operates radially relative to the shaft to provide a sealing interface between the rotating shaft and stationary housing.

Detailed internal construction features should not be inferred solely from the B1 designation without exact CORTECO technical documentation for this product.

What Does CORTECO 01034873 30x52x12 NBR B1 Mean?

The complete designation identifies:

CORTECO - manufacturer

01034873 - product reference

30 mm - nominal inside / shaft diameter

52 mm - nominal outside diameter

12 mm - nominal height

NBR - Nitrile Butadiene Rubber

B1 - CORTECO catalogue profile

The preferred technical identification is:

CORTECO 01034873 + 30x52x12 + NBR + B1

Selection and Interchangeability

When selecting a replacement for CORTECO 01034873, verify at least:

CORTECO reference 01034873 / 01034873B

d = 30 mm

D = 52 mm

H = 12 mm

NBR material

B1 profile

seal geometry

shaft and housing dimensions

operating medium

operating temperature

shaft speed

pressure, where applicable

directional characteristics, if required

Matching only the:

30x52x12 mm

dimensions does not establish complete technical interchangeability.

Even matching dimensions, NBR material and the basic B1 catalogue profile should not override a different CORTECO part number without technical verification.
