CORTECO 01030122B 90x110x15.5 FPM B1BASLDRWX26 Radial Shaft Seal

CORTECO 01030122B 90x110x15.5 FPM B1BASLDRWX26 Radial Shaft Seal

CORTECO 01030122B is a radial shaft seal with nominal dimensions 90x110x15.5 mm, manufactured from FPM – fluoroelastomer. Current product data identifies the profile as B1BASLDRWX26, while the older CORTECO dimensional catalogue lists reference 01030122 as FPM B1BAVISLDRWX26 90x110x15.5.

The exact product data also identifies an auxiliary dust lip and an Alternating Twist sealing structure.

The key current product identification is:

CORTECO + 01030122B + 90x110x15.5 + FPM + B1BASLDRWX26

Important older search identification:

01030122 + B1BAVISLDRWX26

CORTECO 01030122B – Technical Characteristics

CORTECO 01030122B Dimensions

The principal nominal dimensions are:

d: 90 mm – nominal shaft diameter

D: 110 mm – nominal seal outside diameter

B: 15.5 mm – nominal axial width

Complete nominal size:

90x110x15.5 mm

The 15.5 mm width is particularly important when identifying this seal.

Products with the same:

d: 90 mm

and:

D: 110 mm

can have significantly different widths, materials and sealing profiles.

The complete CORTECO identification should therefore be used instead of selecting a seal based only on the 90 mm and 110 mm diameters.

FPM – Fluoroelastomer

The sealing material specified for CORTECO 01030122B is:

FPM – fluoroelastomer

FPM belongs to the family of fluorinated elastomeric materials used in technical sealing applications.

The material is an important part of the product identity:

01030122B + FPM + B1BASLDRWX26

However, the generic FPM material designation does not identify the exact compound formulation used in this specific seal.

Therefore, generic FPM properties should not be used to assign an exact:

• Shore A hardness
• minimum operating temperature
• maximum operating temperature
• maximum pressure
• maximum shaft surface speed
• detailed chemical compatibility range

to this exact CORTECO product without compound-specific documentation.

B1BAVISLDRWX26 vs B1BASLDRWX26

An important identification detail for this product is the difference between the older and current profile descriptions.

The older CORTECO catalogue identifies:

01030122 – B1BAVISLDRWX26

Current product data for:

01030122B

uses:

B1BASLDRWX26

For SEO, AI Search and technical identification, both designations are useful.

The current product page should primarily target:

CORTECO 01030122B B1BASLDRWX26

while retaining:

01030122 B1BAVISLDRWX26

as an older catalogue and search identifier.

This helps users searching from older CORTECO catalogues, packaging, invoices or machine documentation find the current product page.

Alternating Twist

For the exact CORTECO 01030122B, current product data specifies:

Swirl Type: Alternating Twist

This is a confirmed product-specific characteristic rather than an assumption based solely on the profile code.

The alternating hydrodynamic structure distinguishes this execution from seals specified with:

Left-hand Twist

or:

Right-hand Twist.

Rotation-related sealing geometry should be considered when evaluating potential replacements.

Auxiliary Dust Lip

CORTECO 01030122B is specified:

with dust lip

The auxiliary dust lip creates an additional barrier on the external side of the primary sealing area.

It helps protect the main sealing zone against external contamination.

The dust lip is therefore part of the exact product configuration and should be considered when comparing this seal with alternative 90x110 mm designs.

Mercedes-Benz OE Cross-References

The older CORTECO catalogue associates the product with:

MERCEDES TR

while current product data provides Mercedes-Benz OE references including:

0159976947

0129974047

A0159976947

Useful product search identifiers therefore include:

CORTECO 01030122B

CORTECO 01030122

CORTECO 82030122

B1BASLDRWX26

B1BAVISLDRWX26

Mercedes-Benz 0159976947

Mercedes-Benz 0129974047

Mercedes-Benz A0159976947

An OE cross-reference should still be checked against the exact vehicle and application before installation.

Drivetrain Application

Current catalogue data classifies CORTECO 01030122B as a shaft seal associated with the transfer case / drivetrain.

The exact installation position can depend on the specific Mercedes-Benz application.

For this reason, the safest primary technical description remains:

radial shaft seal

with transfer-case or drivetrain application treated as additional product-identification information rather than a universal installation position.

01030122 vs 01030122B

Older CORTECO documentation uses:

01030122

while current product databases identify the seal as:

01030122B

Both numbers belong to the same product identification line associated with the 90x110x15.5 FPM seal.

For the current product page:

01030122B

should be the primary part number.

The earlier:

01030122

should remain indexed as a secondary search reference.

CORTECO 01030122B vs Other 90x110 Shaft Seals

The 90x110 mm diameter combination occurs in numerous shaft-seal configurations.

Seals sharing these basic diameters may differ in:

• axial width
• elastomer
• sealing profile
• dust-lip configuration
• hydrodynamic structure
• rotation-related design
• application

For this product, the key identification is:

CORTECO 01030122B 90x110x15.5 FPM B1BASLDRWX26

This also distinguishes it from other CORTECO and GRN® products already available in similar 90x110 mm dimensions.

Dimensions alone should therefore never be used as proof of interchangeability.

Selection and Interchangeability

When selecting CORTECO 01030122B or evaluating a replacement, verify:

• current part number 01030122B
• earlier reference 01030122
• trade number 82030122
• shaft diameter d: 90 mm
• outside diameter D: 110 mm
• width B: 15.5 mm
• material FPM
• current profile B1BASLDRWX26
• older profile B1BAVISLDRWX26
• Alternating Twist
• auxiliary dust lip
• Mercedes-Benz OE reference
• exact vehicle and drivetrain application

A different 90x110x15.5 mm seal should not automatically be considered interchangeable.
