B2SLSFDRWX6 Simmerring Design

B2SLSFDRWX6 is the exact CORTECO design designation specified for this reference.

It should not be simplified to a standard BA, BASL or another basic radial shaft seal profile because 12015758B has a specific construction intended for its defined application.

For the exact 12015758B B2SLSFDRWX6, the following characteristics are confirmed:

NBR material
100x140x15/20.5 mm dimensions
additional dust lip
alternating twist
front axle installation

The complete B2SLSFDRWX6 designation is therefore important when identifying a technically corresponding replacement.

100x140x15/20.5 mm Dimensions

The complete dimensional specification is:

100x140x15/20.5 mm

The individual dimensions are:

100 mm - inner diameter
140 mm - outer diameter
15 mm - H1 height
20.5 mm - H2 overall height

For this product, the dimension should not be simplified to 100x140x15 mm.

The 20.5 mm overall height forms part of the complete seal geometry and should be retained in the product designation and when selecting a replacement.

Additional Dust Lip

CORTECO 12015758B features a confirmed additional dust lip.

Its function is to help reduce the ingress of external contamination toward the primary sealing area.

This feature is particularly relevant in wheel hub and axle sealing positions where the seal can be exposed to contamination from the surrounding environment.

The dust lip should therefore be considered when comparing this product with alternative seals of similar dimensions.

Alternating Twist

One of the important construction characteristics of CORTECO 12015758B is:

Alternating Twist

This describes the hydrodynamic sealing geometry associated with the sealing contact area.

Unlike seals specified with a single right-hand or left-hand directional twist, this CORTECO reference is identified with an alternating twist configuration.

This characteristic should be retained when identifying a technically equivalent replacement.

NBR - Nitrile Butadiene Rubber

CORTECO 12015758B is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is widely used for radial shaft and wheel hub sealing applications and is compatible with many commonly used mineral oils and lubricating greases.

Actual compatibility should always be verified against the specific lubricant, additives, temperature and operating conditions.

CORTECO 12015758B - Front Axle

The specified installation position for this exact CORTECO reference is:

Front axle

The product is catalogued as a:

wheel hub / radial shaft oil seal

The installation position is an important identification parameter because commercial vehicles can use different sealing designs depending on the axle and hub configuration.

CORTECO 12015758B - DAF Application

The older CORTECO dimensional catalogue identifies:

12015758 - NBR - B2SLSFDRWX6 - 100x140x15/20.5 - DAF

Application catalogues associate this reference with DAF commercial vehicle ranges.

The OE numbers provide a more precise basis for product identification than vehicle model names alone.

Vehicle compatibility should therefore be confirmed using the OE reference together with the exact axle and vehicle configuration.

DAF OE Numbers

Confirmed DAF OE references for CORTECO 12015758B include:

DAF 0363355
DAF 1238034

Cross-reference:

DAF 0363355 -> CORTECO 12015758B

DAF 1238034 -> CORTECO 12015758B

These OE numbers are particularly useful when identifying the correct seal for a specific DAF axle or wheel hub assembly.

CORTECO 12015758B Cross-Reference

Cross-reference catalogues associate this seal with references including:

DAF: 0363355, 1238034
DT Spare Parts: 5.20100
FEBI BILSTEIN: 12282
SAMPA: 050.307
SKT: 412319
AUGER: 57294

Cross-reference numbers should be used as an identification aid.

Before installing an alternative product, its complete dimensions, seal construction and application requirements should be compared.

12015758 vs 12015758B

Both references can appear when searching for this product:

12015758
12015758B

The older CORTECO dimensional catalogue lists:

12015758 - NBR - B2SLSFDRWX6 - 100x140x15/20.5 - DAF

The current complete product reference is:

CORTECO 12015758B

For current product identification, ordering and SEO, 12015758B should therefore be used as the primary reference.

The number 12015758 should remain in the description as an alternative search reference.

12015758B vs 82015758

CORTECO also assigns this product the Trade Number:

82015758

The two numbers serve different identification purposes:

12015758B - CORTECO Part Number
82015758 - CORTECO Trade Number

Both references are valuable for technical product searches and cross-referencing.

Why Is the Complete Designation Important?

The basic 100x140 mm diameters alone do not completely identify this wheel hub seal.

The complete specification includes:

100x140x15/20.5 mm - dimensions
NBR - elastomer material
B2SLSFDRWX6 - CORTECO design
Dust Lip - yes
Twist - alternating
Installation Position - front axle

These characteristics should be considered together when selecting a replacement.

How to Select CORTECO 12015758B

For correct identification, verify:

Manufacturer: CORTECO
Part Number: 12015758B
Trade Number: 82015758
Dimensions: 100x140x15/20.5 mm
Material: NBR
Design: B2SLSFDRWX6 Simmerring
Dust Lip: Yes
Twist: Alternating twist
