Technical data - CORTECO 01034358

What does CORTECO 01034358 NBR B1BAOFSLSFX7 mean?

The complete product designation is:

CORTECO 01034358 NBR B1BAOFSLSFX7 125x180x12/15 mm

This provides considerably more precise identification than using the basic dimensions alone.

CORTECO - manufacturer of the sealing component.

01034358 - base CORTECO product number.

01034358B - reference format used for this seal in aftermarket catalogue systems.

82034358 - additional CORTECO reference associated with this product.

125x180x12/15 mm - complete dimensional designation of the seal.

The full profile and dimensional notation should be retained when identifying or cross-referencing this product.

Dimensions of CORTECO 01034358

The exact catalogue dimensions are:

125x180x12/15 mm

where:

• d = 125 mm - inside diameter
• D = 180 mm - outside diameter
• basic axial width = 12 mm
• additional overall axial dimension = 15 mm

The complete:

12/15 mm

notation is important.

The product should not be simplified to 125x180x12 mm, because the 15 mm value forms part of the dimensional identification of this specific construction.

NBR - Nitrile Rubber

The CORTECO catalogue confirms:

NBR - nitrile rubber

for product 01034358.

NBR is one of the most widely used elastomer families for radial shaft oil seals and is commonly selected for applications involving compatible oils and lubricants.

When evaluating this seal for a particular assembly, consider:

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

A specific temperature range should not be assigned to CORTECO 01034358 solely from generic NBR material data. The permissible operating conditions depend on the exact compound and application.

B1BAOFSLSFX7 construction

The exact CORTECO profile designation is:

B1BAOFSLSFX7

This is one of the most important technical identification parameters for CORTECO 01034358.

When evaluating an equivalent seal, the complete combination should be considered:

CORTECO 01034358 + NBR + B1BAOFSLSFX7 + 125x180x12/15 mm

Individual letters within B1BAOFSLSFX7 should not be assigned detailed construction meanings unless those meanings are explicitly confirmed by manufacturer documentation for this exact product.

This prevents confusion with other CORTECO profiles that may share similar basic dimensions.

Additional dust protection

Product data for CORTECO 01034358B confirms an:

additional dust lip

This auxiliary sealing feature helps protect the primary sealing area against external contamination.

Depending on the operating environment, this may include:

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

This additional sealing feature should be considered when comparing CORTECO 01034358 with alternative 125x180 mm radial shaft seals.

Why are 125x180 mm dimensions not enough?

The basic:

125x180 mm

diameters do not uniquely identify CORTECO 01034358.

Different radial shaft seals can have the same shaft and housing diameters while differing in:

• axial width
• elastomer material
• sealing lip geometry
• additional dust protection
• construction profile
• intended application
• operating characteristics

For this product, the complete dimensional designation:

125x180x12/15 mm

and the construction identification:

NBR B1BAOFSLSFX7

are particularly important.

CORTECO 01034358 vs a standard 125x180x12 mm oil seal

CORTECO 01034358 should not automatically be replaced by a standard:

125x180x12 mm

radial shaft seal.

The exact CORTECO product has the complete dimensional designation:

125x180x12/15 mm

and profile:

B1BAOFSLSFX7

When comparing an alternative, verify:

• d = 125 mm
• D = 180 mm
• 12/15 mm axial dimensions
• NBR material
• B1BAOFSLSFX7 profile
• additional dust protection
• ZF reference
• exact installation position

Matching basic dimensions do not confirm full technical interchangeability.

How to select CORTECO 01034358 correctly

The safest starting point is the exact product reference:

CORTECO 01034358 / 01034358B

or one of the confirmed ZF references:

0501322162

or:

0750112251

Then verify:

1. 125 mm inside diameter
2. 180 mm outside diameter
3. complete 12/15 mm axial dimensions
4. NBR material
5. B1BAOFSLSFX7 profile
6. additional dust protection
7. exact installation position
8. requirements of the specific assembly

Selection and interchangeability checklist

Before ordering, check:

• CORTECO 01034358 / 01034358B
• CORTECO 82034358
• ZF 0501322162 or 0750112251, where applicable
• inside diameter 125 mm
• outside diameter 180 mm
• complete width 12/15 mm
• NBR material
• B1BAOFSLSFX7 profile
• additional dust lip
• installation position

Do not select this product solely by the 125x180 mm shaft and housing diameters.

Installation of CORTECO 01034358

Because of its large diameter and specific construction, CORTECO 01034358 should be installed evenly and squarely.

Before installation, inspect:

• shaft sealing surface
• wear grooves
• scratches
• burrs
• corrosion
• seal housing
• alignment
• shaft runout
• bearing play

Protect the functional sealing surfaces and additional dust lip against cutting, folding or other mechanical damage.

A suitable installation tool should apply force evenly around the appropriate seal surface. A large-diameter radial shaft seal should not be driven into position by applying concentrated force at individual points.

What should be checked if the previous seal was leaking?

If the previous Simmerring was leaking, determine whether another mechanical issue contributed to the failure before installing CORTECO 01034358.

Check:

• shaft sealing surface
• shaft wear groove
• radial runout
• bearing play
• bearing condition
• alignment
• seal housing condition
• lubricant level
• correct lubricant specification
• system pressure and breather condition, where applicable

Installing a new seal may not permanently eliminate leakage if the actual cause is a worn shaft, excessive bearing clearance, misalignment or another mechanical problem.
