Rotary Shaft Seal CORTECO 01034350 BASFX2 Oil Seal 30x50x10

CORTECO 01034350 HNBR BASFX2 30x50x10 mm - Radial Shaft Oil Seal Simmerring

CORTECO 01034350 HNBR BASFX2 30x50x10 mm is a radial shaft sealing ring from the Simmerring family. Current CORTECO catalogue data identifies this product with HNBR material, BASFX2 profile and dimensions of 30x50x10 mm. The seal is also referenced as CORTECO 01034350B and 82034350. A confirmed Mercedes-Benz OE reference is 00097471057.

Technical data - CORTECO 01034350

What does CORTECO 01034350 HNBR BASFX2 mean?

The complete current product identification is:

CORTECO 01034350 HNBR BASFX2 30x50x10 mm

Each part of the designation helps distinguish this seal from other products with the same basic dimensions.

CORTECO - manufacturer of the sealing component.

01034350 - base CORTECO product number.

01034350B - reference format used for this seal in aftermarket catalogue systems.

82034350 - additional CORTECO reference associated with this product.

HNBR - hydrogenated nitrile rubber used as the elastomer material.

BASFX2 - exact CORTECO profile designation.

30x50x10 mm - nominal dimensions of the seal.

Important catalogue note: HNBR or NEM?

Two material-related designations can be encountered for CORTECO 01034350.

Older CORTECO dimensional catalogue data lists the product as:

01034350 NEM BASFX2 30x50x10

More recent CORTECO product data identifies the same reference as:

01034350B BASFX2 HNBR 30x50x10

For a current product listing, the recommended primary designation is therefore:

CORTECO 01034350 HNBR BASFX2 30x50x10 mm

The term NEM remains useful in the product description because customers may encounter it in older CORTECO catalogues, technical documentation and historical product searches.

Dimensions of CORTECO 01034350

The confirmed dimensions are:

30x50x10 mm

where:

• d = 30 mm - inside diameter
• D = 50 mm - outside diameter
• B = 10 mm - width

The inside diameter corresponds to the nominal diameter of the mating shaft surface.

The outside diameter corresponds to the nominal seal housing diameter.

The axial width is 10 mm.

Dimensions are essential for identification, but they are not sufficient on their own to establish full interchangeability.

HNBR - Hydrogenated Nitrile Rubber

Current product data identifies the material of CORTECO 01034350B as:

HNBR - Hydrogenated Nitrile Butadiene Rubber

HNBR is an elastomer family used in technical sealing components where its particular combination of material properties is required.

When selecting a seal for a specific application, consider:

• operating medium
• lubricant or fluid specification
• operating temperature
• shaft speed
• shaft surface condition
• lubrication conditions
• system pressure, where applicable
• assembly design
• equipment manufacturer requirements

A specific operating temperature range should not be assigned to CORTECO 01034350 solely from generic HNBR data. The permissible limits depend on the exact compound and application.

BASFX2 construction

The exact profile designation for this product is:

BASFX2

The profile is an important part of the technical identity of CORTECO 01034350.

When evaluating a replacement, consider the complete combination:

CORTECO 01034350 + HNBR + BASFX2 + 30x50x10 mm

A different radial shaft seal with dimensions of 30x50x10 mm should not automatically be considered equivalent.

Individual letters and numbers within BASFX2 should not be assigned detailed construction meanings unless these are explicitly confirmed by CORTECO documentation for this exact product.

CORTECO 01034350 and Mercedes-Benz 00097471057

A confirmed OE reference associated with CORTECO 01034350B is:

MERCEDES-BENZ 00097471057

The number may also appear in Mercedes-Benz formatting as:

A00097471057

The reference relationship is therefore:

CORTECO 01034350 / 01034350B

CORTECO 82034350

MERCEDES-BENZ 00097471057

The OE reference is particularly valuable for identification because many different radial shaft seals are available in the common 30x50x10 mm size.

Steering system application

CORTECO 01034350 / 01034350B appears in application data associated with sealing positions in power steering systems.

This information helps identify the intended use of the product but should not be interpreted as universal compatibility with every Mercedes-Benz steering system.

For a specific vehicle or steering assembly, verify:

• OE number
• steering gear or assembly type
• exact installation position
• dimensions
• material
• BASFX2 profile

Selection based only on the vehicle manufacturer is not sufficient.

CORTECO 01034350 vs a standard 30x50x10 mm oil seal

CORTECO 01034350 should not automatically be replaced by any standard:

30x50x10 mm

radial shaft seal.

Seals sharing identical nominal dimensions may differ in:

• elastomer material
• sealing profile
• lip geometry
• external construction
• operating characteristics
• intended application

For this product, the particularly important identification combination is:

HNBR + BASFX2 + 30x50x10 mm

For the relevant Mercedes-Benz application, the OE reference:

00097471057

provides another important identification parameter.

How to select CORTECO 01034350 correctly

The safest starting point is the exact product reference:

CORTECO 01034350 / 01034350B

or the confirmed Mercedes-Benz reference:

00097471057

Then verify:

1. inside diameter - 30 mm
2. outside diameter - 50 mm
3. width - 10 mm
4. HNBR material
5. BASFX2 profile
6. exact installation position
7. requirements of the specific assembly

If older documentation or the original seal is associated with the designation NEM BASFX2, this may also lead to CORTECO 01034350.

Selection and interchangeability checklist

Before ordering, verify:

• CORTECO 01034350 / 01034350B
• CORTECO 82034350
• Mercedes-Benz 00097471057, where applicable
• d = 30 mm
• D = 50 mm
• B = 10 mm
• HNBR material
• BASFX2 profile
• installation position
• requirements of the specific assembly

Matching 30x50x10 mm dimensions alone do not confirm full technical interchangeability.

Installation of CORTECO 01034350

Before installation, thoroughly clean the seal housing and mating surface.

Inspect:

• shaft surface
• wear grooves
• scratches
• burrs
• corrosion
• housing condition
• alignment
• excessive play in mating components

Install the seal evenly and squarely using a suitable installation tool.

Protect the functional sealing elements from folding, cutting or damage when passing over sharp edges or other potentially damaging features.

What should be checked if the previous seal was leaking?

If the previous seal leaked, replacing the Simmerring alone may not solve the underlying problem.

Check:

• mating surface condition
• shaft wear
• runout
• excessive play
• bearing or guiding element condition
• alignment
• seal housing
• correct operating fluid
• operating conditions of the assembly

A new seal can develop another leak if the underlying cause is excessive wear, misalignment or mechanical damage.
