CORTECO 12003473 NBR B2 115x140x13 Rotary Shaft Seal

CORTECO 12003473 / 12003473B is an NBR radial shaft seal measuring 115x140x13 mm. The exact CORTECO design designation is B2, while current catalogue data identify the seal for the axle beam / wheel hub sealing position. Confirmed OE references include MAN 06562890037, 87660304900, 90752541141 and Mercedes-Benz 0119975446.

CORTECO 12003473 - Characteristics

The technical identity of this specific product can be expressed as:

12003473 -> CORTECO -> NBR -> B2 -> 115x140x13 mm -> radial shaft seal -> axle beam / wheel hub

CORTECO dimensional documentation identifies this reference as:

12003473 - NBR - B2 - 115x140x13 - MERCEDES TR

Current parts catalogues also list the product as CORTECO 12003473B.

This complete identification is important because other seals with the same 115x140x13 mm dimensions may use different elastomers and different sealing profiles.

Dimensions

The confirmed dimensions are:

Inside Diameter: 115 mm
Outside Diameter: 140 mm
Width: 13 mm
Complete Size: 115x140x13 mm

The dimensions should be considered together with the NBR material, B2 design and relevant OE reference when selecting the seal.

A dimensional match alone is not sufficient to establish technical interchangeability.

B2 Seal Design

The exact CORTECO design designation for reference 12003473 is:

B2

The B2 designation is an integral part of the product specification and distinguishes this reference from other CORTECO seals with the same nominal dimensions.

CORTECO catalogues several 115x140x13 mm seals with different design codes and materials. Therefore, the combination:

CORTECO 12003473 + NBR + B2 + 115x140x13 mm

provides significantly more precise identification than the dimensions alone.

NBR Material

CORTECO specifies NBR - nitrile butadiene rubber for reference 12003473.

NBR is widely used as an elastomer in radial shaft sealing systems, particularly with many mineral-oil-based lubricants and greases.

However, material suitability should always be verified against the actual medium and operating conditions. A specific temperature range, maximum shaft speed or universal chemical compatibility is not assigned here because these parameters have not been sufficiently confirmed for this exact CORTECO configuration.

Axle Beam / Wheel Hub Application

Current catalogue data identify CORTECO 12003473B for an axle beam sealing position and also classify the product in relation to wheel hub sealing.

CORTECO dimensional documentation additionally associates the reference with:

MERCEDES TR

This provides a more precise technical context than describing the product simply as a generic 115x140x13 mm oil seal.

Vehicle compatibility should nevertheless be determined from the relevant OE number and the specific vehicle configuration rather than from the vehicle manufacturer alone.

MAN OE References

The following MAN references are associated with CORTECO 12003473:

MAN 06562890037
MAN 87660304900
MAN 90752541141

The first reference may also appear in formatted catalogues as:

06.56289.0037

These OE numbers provide an important identification route when searching for the correct seal.

Mercedes-Benz OE Reference

The confirmed Mercedes-Benz OE reference is:

MERCEDES-BENZ 0119975446

It may also be displayed in spaced format as:

011 997 54 46

The OE reference should be checked against the specific vehicle or assembly before installation.

Additional Cross-References

Current cross-reference catalogues associate CORTECO 12003473B with:

ELRING: 518.166
FEBI BILSTEIN: 40531
GOETZE: 5030037100
PAYEN: NF310
VICTOR REINZ: 81-35102-00

These cross-references provide stronger identification than dimensional similarity alone. The complete technical specification and application should still be verified before substitution.

CORTECO 12003473 vs GRN 115x140x13 NBR TC

Both seals have nominal dimensions of 115x140x13 mm and both are specified in NBR, but they should not automatically be treated as identical products.

CORTECO 12003473 -> NBR -> B2 -> 115x140x13 mm

GRN 115x140x13 -> NBR -> TC -> double-lip design

The design profile is a fundamental selection parameter. Matching the dimensions and base elastomer alone does not establish complete interchangeability.

CORTECO 12003473 vs CORTECO 20029785

CORTECO also offers another technically different seal with the same 115x140x13 mm dimensions:

CORTECO 12003473 -> NBR -> B2 -> 115x140x13 mm

CORTECO 20029785 -> PTFE/TFE -> B1BAPTSLRSX7 -> 115x140x13 mm

The two references therefore differ in both material and design configuration. They should not be considered the same product solely because their nominal dimensions are identical.

Selection and Interchangeability

When selecting a replacement for CORTECO 12003473 / 12003473B, verify:

• CORTECO reference
• 115 mm inside diameter
• 140 mm outside diameter
• 13 mm width
• NBR material
• B2 design
• fitting position
• MAN or Mercedes-Benz OE reference
• construction of the proposed replacement

Matching 115x140x13 mm dimensions alone does not establish full technical interchangeability.

This is particularly important for this size because several technically different shaft seals are available with the same nominal dimensions.
