CORTECO 01035208 FPM BAUM4SLX7 55x75x8 mm - Gearbox Radial Shaft Oil Seal Simmerring

CORTECO 01035208 FPM BAUM4SLX7 55x75x8 mm - Gearbox Radial Shaft Oil Seal Simmerring

CORTECO 01035208 FPM BAUM4SLX7 55x75x8 mm is a radial shaft oil seal from the Simmerring family for specified Mercedes-Benz transmission applications. The CORTECO catalogue identifies this seal with FPM fluoroelastomer material and BAUM4SLX7 profile. Its dimensions are 55 mm inside diameter, 75 mm outside diameter and 8 mm width. The product is also referenced as CORTECO 01035208B and 82035208.

Technical data - CORTECO 01035208

What does CORTECO 01035208 FPM BAUM4SLX7 mean?

The complete product identification is:

CORTECO 01035208 FPM BAUM4SLX7 55x75x8 mm

Each element helps distinguish this seal from other products that may share the same basic dimensions.

CORTECO - manufacturer of the sealing component.

01035208 - base CORTECO product number.

01035208B - reference format used for this product in aftermarket catalogue systems.

82035208 - additional CORTECO reference associated with this seal.

FPM - fluoroelastomer sealing material.

BAUM4SLX7 - CORTECO profile designation for this specific construction.

55x75x8 mm - nominal dimensions of the radial shaft seal.

Product data for CORTECO 01035208B also confirms an additional dust lip.

Dimensions of CORTECO 01035208

The CORTECO catalogue specifies:

55x75x8 mm

where:

• d = 55 mm - inside diameter
• D = 75 mm - outside diameter
• B = 8 mm - width

The 55 mm inside diameter corresponds to the nominal shaft diameter at the sealing surface.

The 75 mm outside diameter corresponds to the nominal seal housing diameter.

The axial width is 8 mm.

These dimensions are important for identification, but dimensions alone are not sufficient to establish full technical interchangeability.

FPM fluoroelastomer

The material confirmed by the CORTECO catalogue for product 01035208 is:

FPM - fluoroelastomer

The designation FKM is also widely used internationally for this elastomer family.

FPM/FKM materials are commonly used for technical radial shaft seals operating in contact with oils and lubricants and in applications requiring the properties of a fluoroelastomer.

When selecting this seal, consider:

• lubricant type
• operating temperature
• shaft speed
• shaft surface condition
• lubrication conditions
• transmission design
• equipment manufacturer requirements

A specific operating temperature range should not be assigned to CORTECO 01035208 solely from generic FPM material data. Actual operating limits depend on the exact compound and application.

FPM/FKM should also not automatically be described as Viton. Viton is a trademark for specific fluoroelastomer materials, while FPM and FKM identify the general elastomer family.

BAUM4SLX7 construction

The exact profile specified for CORTECO 01035208 is:

BAUM4SLX7

This designation is an important part of the technical identity of the seal.

When evaluating a replacement, the complete combination should be considered:

CORTECO 01035208 + FPM + BAUM4SLX7 + 55x75x8 mm

A different 55x75x8 mm Simmerring with another CORTECO profile should not automatically be considered technically equivalent.

Individual letters or numbers within BAUM4SLX7 should not be assigned detailed construction meanings unless these are explicitly confirmed by manufacturer documentation for this exact product.

Additional dust lip

Product data for CORTECO 01035208B confirms an:

additional dust lip

The additional lip helps protect the primary sealing area against contamination entering from the external side.

Depending on the operating environment, contamination may include:

• dust
• dirt
• fine particles
• moisture
• general operating contamination

The dust lip is therefore an important construction feature when comparing CORTECO 01035208 with alternative radial shaft seals.

CORTECO 01035208 - Mercedes-Benz application

The CORTECO dimensional catalogue associates product:

01035208

with:

MERCEDES

Additional application data identifies CORTECO 01035208B as a shaft seal used in specified Mercedes-Benz gearbox and transmission applications.

The exact installation position depends on the particular transmission configuration.

For this reason, selection should be based on the OE number and transmission identification in addition to the 55x75x8 mm dimensions.

CORTECO 01035208 vs Mercedes-Benz 0139978046

A confirmed OE reference for this seal is:

MERCEDES-BENZ 0139978046

It may also be written as:

A0139978046

The reference relationship is therefore:

CORTECO 01035208 / 01035208B

MERCEDES-BENZ 0139978046

MERCEDES-BENZ A0139978046

These references provide a much more precise identification route than searching only by dimensions.

The exact transmission and installation position should still be confirmed before fitting.

Mercedes-Benz transmission applications

Application data associated with CORTECO 01035208 / 01035208B includes specified Mercedes-Benz transmission configurations from families such as:

• 717.900
• 717.901
• 717.902
• 717.903
• 717.930
• 717.933
• 718.800
• 718.801
• 718.811

Transmission data also includes designations from the:

UG 3/40

and:

UG 3/65

families.

These are application references for specified transmission configurations and should not be interpreted as universal compatibility with every Mercedes-Benz gearbox.

The safest identification combines:

OE number + transmission type + dimensions + seal construction

Alternative designations and reference numbers

Useful identification and search variants include:

• CORTECO 01035208
• CORTECO 01035208B
• 01035208 CORTECO

CORTECO 01035208 vs other 55x75x8 mm oil seals

The CORTECO catalogue demonstrates why the basic:

55x75x8 mm

dimensions should not be used as the only selection criterion.

Other radial shaft seals can share these dimensions while differing in:

• elastomer material
• sealing profile
• lip configuration
• construction
• intended application

For CORTECO 01035208, the particularly important identification combination is:

FPM + BAUM4SLX7 + 55x75x8 mm

When comparing an alternative seal, verify:

• inside diameter: 55 mm
• outside diameter: 75 mm
• width: 8 mm
• FPM material
• BAUM4SLX7 profile
• additional dust lip
• OE reference
• transmission type
• installation position

Identical dimensions do not automatically confirm technical interchangeability.

How to select CORTECO 01035208 correctly

The safest starting point is the exact CORTECO reference:

01035208 / 01035208B

or the confirmed Mercedes-Benz OE reference:

0139978046 / A0139978046

Then verify:

1. dimensions 55x75x8 mm
2. FPM material
3. BAUM4SLX7 profile
4. additional dust lip
5. transmission type
6. installation position
7. requirements of the specific assembly

For Mercedes-Benz applications, the exact transmission or assembly number should be checked where available.

Selection and interchangeability checklist

Before ordering, verify:

• CORTECO 01035208 / 01035208B
• Mercedes-Benz 0139978046 / A0139978046, where applicable
• d = 55 mm
• D = 75 mm
• B = 8 mm
• FPM material
• BAUM4SLX7 profile
• additional dust lip
• transmission type
• exact installation position

Selection based only on the 55x75x8 mm dimensions is not sufficient.

Installation of CORTECO 01035208

Before installation, thoroughly clean the shaft sealing surface and seal housing.

Inspect:

• shaft sealing surface
• wear grooves
• scratches
• burrs
• corrosion
• housing condition
• alignment
• excessive shaft play

During installation, protect both the primary sealing area and the additional dust lip against damage.

The Simmerring should be pressed evenly and squarely into the housing using a suitable installation tool.

Avoid damaging the sealing area when passing the seal over shaft edges, splines or other sharp features.

What should be checked if the gearbox seal was leaking?

If the previous seal was leaking, inspect the surrounding components before installing CORTECO 01035208.

Check:

• shaft sealing surface
• shaft runout
• bearing play
• bearing condition
• alignment
• seal housing
• lubricant level
• correct lubricant specification
• transmission breather, where applicable

Replacing the Simmerring alone may not eliminate leakage if the actual cause is shaft wear, excessive bearing play, misalignment or another mechanical problem.
