CORTECO 01027678 81x100x10 NBR B1BAX1 Radial Shaft Seal

CORTECO 01027678 is an NBR radial shaft seal with B1BAX1 design and dimensions 81x100x10 mm. The inner diameter is 81 mm, the outer diameter is 100 mm and the width is 10 mm. Current technical catalogues identify the corresponding commercial reference as 01027678B, trade number 82027678, and classify it as a wheel hub shaft seal. The confirmed MAN OE cross-reference is 06562890320.

CORTECO 01027678 - Product Characteristics

The exact catalogue data for the corresponding 01027678B product specify:

Brand: CORTECO
Material: NBR
Design: B1BAX1 Simmerring
Dimensions: 81x100x10 mm
Trade Number: 82027678
Catalogue Product Type: Shaft seal, wheel hub
MAN OE: 06562890320

These parameters identify a specific CORTECO seal configuration rather than a generic 81x100x10 oil seal. The dimensions, elastomer and B1BAX1 design should all be considered when selecting a replacement.

Dimensions

The verified dimensions of CORTECO 01027678 / 01027678B are:

Inner Diameter: 81 mm
Outer Diameter: 100 mm
Width / Height: 10 mm
Commercial Size: 81x100x10 mm

For this radial shaft seal, the size notation 81x100x10 mm corresponds to the inner diameter, outer diameter and axial width respectively.

The dimensional values are consistently reported in current catalogue sources for the exact 01027678B reference.

B1BAX1 Seal Design

The design designation for this CORTECO seal is B1BAX1.

This designation should be treated as part of the exact technical identification of the product. A seal with the same 81x100x10 mm dimensions but a different profile should not automatically be regarded as technically identical.

Available catalogue data confirm the designation B1BAX1 Simmerring, but they do not provide enough detail to safely assign an additional dust lip, directional helix or other construction feature to this exact reference. Those characteristics are therefore not added here without stronger manufacturer-level confirmation.

NBR Material

CORTECO 01027678B is specified in NBR, or nitrile butadiene rubber.

Material is an important selection parameter for radial shaft seals. A dimensionally identical seal manufactured from ACM, FKM/FPM, VMQ or another elastomer should not automatically be considered equivalent to this NBR version.

No exact operating-temperature range is assigned to this product here. A generic temperature range for NBR would not prove the approved operating limits of the exact CORTECO compound used in 01027678B.

Wheel Hub Application

Current technical catalogues classify CORTECO 01027678B as a shaft seal, wheel hub.

This classification is product-specific and therefore can be used as a verified application category. It does not, however, mean that the seal should be assumed to fit every MAN wheel hub or every MAN commercial vehicle.

Vehicle and axle compatibility should be confirmed using the OE number 06562890320 and, where necessary, the exact vehicle type, axle configuration or chassis-specific parts catalogue.

MAN OE 06562890320

The confirmed OE cross-reference for this CORTECO seal is:

MAN: 06562890320

This OE number is consistently associated with CORTECO 01027678B in current technical catalogues.

The OE reference is particularly useful when identifying the seal in MAN commercial vehicle applications. Nevertheless, final fitment should be checked against the parts documentation for the exact vehicle or axle assembly.

CORTECO Product References

The following identifiers are associated with this product:

01027678 - base CORTECO reference used for this product page
01027678B - current catalogue / TecDoc reference
82027678 - CORTECO trade number
B1BAX1 Simmerring - design / trade designation
MAN 06562890320 - OE cross-reference

Current catalogues consistently connect 01027678B, 82027678 and B1BAX1 Simmerring with the same 81x100x10 mm NBR seal.

Selection and Interchangeability

A replacement for CORTECO 01027678 should not be selected solely because it has dimensions of 81x100x10 mm.

The following parameters should be compared:

• inner diameter: 81 mm,
• outer diameter: 100 mm,
• width: 10 mm,
• NBR material,
• B1BAX1 design,
• wheel hub application where relevant,
• MAN OE 06562890320,
• exact installation position and axle specification.

Other manufacturers may offer products cross-referenced to the same MAN OE number, but dimensional similarity alone does not prove complete technical interchangeability.

Installation Considerations

Before installation, inspect the shaft or mating surface and the seal housing for wear, corrosion, scoring or contamination.

The seal should be pressed into the housing evenly without deforming its body or damaging the sealing element.

Correct installation depth and orientation should follow the technical documentation for the specific MAN hub or axle assembly. When the replacement is being selected by OE number, the MAN specification for 06562890320 should take priority over generic seal installation guidance.

FAQ

What are the dimensions of CORTECO 01027678?

CORTECO 01027678 measures 81x100x10 mm: 81 mm inner diameter, 100 mm outer diameter and 10 mm width.

What material is CORTECO 01027678 made from?

The seal is manufactured from NBR, or nitrile butadiene rubber.

What is B1BAX1?

B1BAX1 is the design designation associated with this exact CORTECO shaft seal. It should be considered during replacement selection rather than relying on dimensions alone.

What is the current catalogue reference for CORTECO 01027678?

Current technical catalogues identify the corresponding product as CORTECO 01027678B, with trade number 82027678.

What MAN OE number corresponds to CORTECO 01027678B?

The confirmed MAN OE cross-reference is 06562890320.

Is CORTECO 01027678B a wheel hub seal?

Yes. Current catalogue data classify 01027678B as a shaft seal, wheel hub.

Can any 81x100x10 oil seal replace CORTECO 01027678?

No. The replacement should also match the NBR material, B1BAX1 design, application requirements and MAN OE 06562890320.

Does CORTECO 01027678B have a dust lip?

The reviewed catalogue data confirm B1BAX1, but do not provide sufficiently strong evidence to specify an additional dust lip for this exact reference. It should therefore not be claimed without further manufacturer documentation.
