CORTECO 01036457B 40x83x8 ACM B1BASLSFDRWX6 Radial Shaft Seal

CORTECO 01036457B 40x83x8 ACM B1BASLSFDRWX6 Radial Shaft Seal

CORTECO 01036457B is a transfer case radial shaft seal with nominal dimensions 40x83x8 mm. It is manufactured from ACM (Polyacrylate Rubber) and its exact CORTECO profile designation is B1BASLSFDRWX6. The construction incorporates an additional dust lip and is catalogued with an alternating twist sealing structure.

The key product identification is:

CORTECO + 01036457B + 40x83x8 mm + ACM + B1BASLSFDRWX6

CORTECO 01036457B – Technical Characteristics

The exact combination of reference, dimensions, material and profile is important when identifying this seal. A different 40x83x8 mm radial shaft seal should not automatically be considered technically equivalent.

CORTECO 01036457B Dimensions

The verified nominal dimensions are:

d = 40 mm – inside / shaft diameter
D = 83 mm – outside diameter
H = 8 mm – height

Complete dimensional designation:

40x83x8 mm

Dimensions alone are not sufficient for selecting a replacement. A seal with the same 40x83x8 mm dimensions may differ in elastomer material, sealing-lip geometry, dust protection or directional sealing structure.

B1BASLSFDRWX6 – Exact CORTECO Profile

The exact CORTECO profile designation for this reference is:

B1BASLSFDRWX6

This complete designation should be retained in technical documentation, product titles and replacement searches.

It should not be shortened to B1BASLSFDRW merely because this shorter designation appears in some secondary catalogues.

The available product data confirms B1BASLSFDRWX6 as the profile assigned to CORTECO 01036457B, but does not provide a sufficiently detailed product-specific explanation of every element of the code.

For this reason, the individual elements such as B1, BA, SL, SF, DRW and X6 should not be independently decoded without appropriate CORTECO documentation.

Radial Shaft Seal Construction and Dust Lip

CORTECO 01036457B incorporates an additional dust lip.

The primary sealing lip performs the principal sealing function around the rotating shaft. The auxiliary dust lip provides an additional barrier on the external side of the sealing system, helping limit the ingress of dust and external contamination toward the primary sealing area.

This feature should be considered when evaluating a replacement. A 40x83x8 mm seal without an additional dust lip should not automatically be treated as constructionally identical to B1BASLSFDRWX6.

ACM – Polyacrylate Rubber

The specified elastomer for CORTECO 01036457B is:

ACM – Polyacrylate Rubber

ACM is an elastomer used in sealing technology, including radial shaft seal applications.

For this exact CORTECO reference, however, the available product-specific documentation does not establish the precise ACM compound or an individual operating-temperature range.

Therefore, no generic ACM temperature range is assigned to 01036457B in this description.

When selecting a technically equivalent seal, ACM should be considered an important identification parameter together with dimensions, lip construction and sealing geometry.

Alternating Twist Sealing Structure

Catalogue data for CORTECO 01036457B identifies the directional characteristic as:

Alternating Twist

Some catalogue systems translate this parameter as a variable or alternating thread.

This terminology should not be confused with a conventional mechanical thread used to screw the seal into its housing. In this context, it describes a feature associated with the sealing structure.

The CORTECO dimensional data also associates this reference with the code:

WD

Because the available product-specific documentation does not provide a sufficiently clear definition of WD, the code is retained without assigning it an unsupported technical interpretation.

Transfer Case Shaft Seal

CORTECO 01036457B is catalogued as a:

Shaft Seal, Transfer Case

This provides a more precise product identification than simply describing it as a generic 40x83x8 oil seal.

For maintenance and replacement identification, the combination:

01036457B + 40x83x8 + ACM + B1BASLSFDRWX6 + OE reference

provides a much stronger basis for selection than dimensions alone.

Audi, Seat and VW OE References

The following OE references are associated with CORTECO 01036457B:

These OE numbers provide an important additional identification route when searching for the correct transfer case shaft seal.

For a specific vehicle, the OE reference should still be checked against the vehicle and drivetrain configuration before installation.

01036457 or 01036457B?

The product data used for this description identifies the seal as:

CORTECO 01036457B

This reference is directly associated with:

40x83x8 mm + ACM + B1BASLSFDRWX6

Therefore, 01036457B should be used as the primary product reference in the product title and technical specification.

If the shorter reference 01036457 occurs in older documentation, stock records or searches, it can be retained as an additional search reference. It should not, however, replace the currently confirmed 01036457B designation without supporting CORTECO documentation.

Selection and Interchangeability

When selecting a replacement for CORTECO 01036457B, verify more than the basic dimensions.

The key identification parameters are 40 mm shaft diameter, 83 mm housing diameter, 8 mm height, ACM material, B1BASLSFDRWX6 profile, additional dust lip, alternating twist sealing structure and the relevant OE reference.

A different radial shaft seal measuring 40x83x8 mm is therefore not automatically interchangeable.

Differences in elastomer, primary lip geometry, auxiliary lip construction or directional sealing features may be technically significant.

Technical Specification

FAQ

What are the dimensions of CORTECO 01036457B?
The nominal dimensions are 40x83x8 mm: 40 mm inside diameter, 83 mm outside diameter and 8 mm height.

What material is CORTECO 01036457B made from?
The specified material is ACM – Polyacrylate Rubber.

What is the profile of CORTECO 01036457B?
The exact CORTECO profile designation is B1BASLSFDRWX6.

Does CORTECO 01036457B have a dust lip?
Yes. The construction incorporates an additional dust lip protecting the primary sealing area against external contamination.

What does Alternating Twist mean for CORTECO 01036457B?
It describes a directional feature associated with the sealing structure. It does not mean that the complete seal has a conventional mounting thread.

Where is CORTECO 01036457B used?
It is catalogued as a transfer case shaft seal.

Which OE numbers correspond to CORTECO 01036457B?
