When identifying or ordering the product, the complete designation should be retained wherever possible.

32x45x7 mm - Mounting Dimensions

The dimensions specify:

• 32 mm - nominal shaft diameter.

• 45 mm - nominal housing bore diameter.

• 7 mm - nominal axial seal width.

These dimensions define the nominal installation geometry.

They do not independently establish the permissible operating pressure, shaft speed or temperature range.

NBR - Nitrile Rubber

NBR stands for acrylonitrile-butadiene rubber, commonly known as nitrile rubber.

It is widely used in industrial sealing applications involving many mineral oils, greases and lubricants.

Its suitability depends on the chemical composition of the operating medium, temperature and the specific elastomer formulation.

NBR should not be assumed to be compatible with every fluid or chemical.

BABSL0,5 - Special Seal Design Profile

BABSL0,5 identifies a specific CORTECO rotary shaft seal construction.

It must not be treated as automatically equivalent to a standard BASL or any other double lip oil seal with matching dimensions.

This version is marketed as a pressure-resistant rotary shaft oil seal and incorporates an additional dust lip.

The complete designation BABSL0,5 should be preserved when identifying the component.

The element 0,5 must not be interpreted as an independently verified operating pressure rating without supporting manufacturer documentation.

Original Equipment Reference Numbers

The following OE and catalogue cross-references are associated with CORTECO 19026533B.

These numbers are catalogue references and do not establish compatibility with every vehicle or machine manufactured by the listed companies.

Before ordering, verify the exact mechanical assembly, original part number and operating requirements.

Construction and Operating Principle

Primary Sealing Lip

The primary sealing lip operates in contact with the rotating shaft surface.

Its purpose is to restrict the escape of the operating medium from the sealed mechanical assembly.

Effective sealing depends on:

• Correct sealing lip contact geometry.

• Shaft surface condition.

• Suitable lubrication.

• Operating temperature.

• Rotational speed.

• Pressure conditions.

• Shaft alignment.

• Correct installation.

Additional Dust Lip

The additional lip helps reduce the entry of external contaminants into the primary sealing area.

It provides an extra barrier against dust and fine particles.

However, it does not automatically guarantee complete protection against pressurised water, immersion or aggressive cleaning conditions.

NBR Sealing Elastomer

The NBR elastomer forms the flexible sealing element that operates against the shaft surface.

Its chemical and thermal suitability must be verified for the actual operating medium.

BABSL0,5 Pressure-Resistant Design

Rotary shaft seals intended for applications involving elevated pressure require careful consideration of sealing lip geometry, support conditions and shaft operating parameters.

Pressure capability cannot be transferred from another CORTECO profile to BABSL0,5 without technical verification.

Commercial product information describes this version as pressure-resistant.

One supplier specifies a pressure value below 10 bar. However, without complete test conditions, this must not be interpreted as a universal continuous operating pressure limit.

The permissible pressure for a specific application must be verified in relation to shaft speed, temperature, lubricant and installation conditions.

CORTECO 19026533B vs Other 32x45x7 mm Oil Seals

CORTECO offers other rotary shaft seals with the same nominal dimensions.

Identical dimensions do not establish technical interchangeability.

CORTECO 19026533B vs CORTECO 12011139

Both products have dimensions of 32x45x7 mm and use NBR sealing material.

However, their design profiles differ:

• CORTECO 19026533B - BABSL0,5.

• CORTECO 12011139 - BASL.

The simmering.pl commercial catalogue identifies 12011139 as superseded by 19026533B.

This does not mean that every BASL oil seal can be replaced with a BABSL0,5 version.

The requirements of the specific assembly must still be checked.

CORTECO 19026533B vs Standard BA Oil Seals

The BA profile represents a different sealing construction.

Matching dimensions of 32x45x7 mm do not confirm identical sealing lip geometry or permissible operating conditions.

Particular care is required when replacing a pressure-resistant seal with a standard design.

Selection and Interchangeability

Before purchasing CORTECO 19026533B, verify the following:

1. Original manufacturer part number.

2. BABSL0,5 design profile.

3. Nominal shaft diameter of 32 mm.

4. Nominal housing bore diameter of 45 mm.

5. Seal width of 7 mm.

6. NBR elastomer material.

7. Type of operating medium.

8. Operating pressure.

9. Shaft rotational speed.

10. Operating temperature.

11. Shaft surface condition.

12. Installation geometry and support conditions.

In pressure-related sealing applications, matching dimensions alone are not sufficient.

The seal construction must also be compatible with the operating requirements of the assembly.

Can a Standard 32x45x7 mm Oil Seal Replace BABSL0,5?

Not automatically.

A standard oil seal may have a different sealing lip construction and different pressure capabilities.

The replacement must be assessed against the original technical requirements.

Can Another CORTECO Profile Be Used?

Only if the replacement is supported by a manufacturer cross-reference or an appropriate technical assessment.

Similar dimensions and materials do not establish complete equivalence.

Why Is Pressure Important?

Pressure acting on the sealing lip can influence contact forces, friction, temperature and wear.

The relationship between pressure and permissible shaft speed must be considered when selecting a pressure-resistant rotary shaft seal.
