Technical data - CORTECO 01033389

What does CORTECO 01033389 FPM BABSL05 mean?

The complete technical identification is:

CORTECO 01033389 FPM BABSL05 28x40x6/6.5 mm

CORTECO - manufacturer of the sealing component.

01033389 - base CORTECO product number.

01033389B - aftermarket catalogue reference associated with this product.

82033389 - additional CORTECO reference.

FPM - fluoroelastomer material used for the sealing element.

BABSL05 - precise profile designation used in current product data.

28x40x6/6.5 mm - complete dimensional specification.

Exact dimensions of CORTECO 01033389

The complete dimensions are:

28x40x6/6.5 mm

where:

• d = 28 mm - inside diameter
• D = 40 mm - outside diameter
• B1 = 6 mm - basic axial width
• B2 = 6.5 mm - additional axial dimension

For technical identification, the complete:

28x40x6/6.5 mm

designation should be retained.

It should not be unnecessarily simplified to:

28x40x6 mm

because the 6.5 mm value forms part of the complete geometry of this specific CORTECO seal.

FPM fluoroelastomer

CORTECO specifies:

FPM

for CORTECO 01033389.

FPM is the European designation commonly used for the fluoroelastomer material family also widely designated as FKM.

Fluoroelastomers are used in technical radial shaft sealing applications where the properties of this material family are required by the operating environment.

Correct selection should take into account:

• operating medium
• lubricant specification
• operating temperature
• shaft speed
• shaft surface condition
• lubrication conditions
• pressure conditions
• design of the sealing position

A specific operating temperature range should not be assigned to CORTECO 01033389 solely from generic FPM material properties. Actual operating limits depend on the exact compound and application.

FPM/FKM should also not automatically be described as Viton. Viton is a trademark used for specific fluoroelastomer materials.

BABSL05 profile

Current product data for CORTECO 01033389B specifies:

BABSL05

Older CORTECO dimensional catalogue data may show the shorter designation:

BABSL

For current product identification, the more specific:

BABSL05

designation is therefore useful and should be retained.

The key identification combination is:

FPM + BABSL05 + 28x40x6/6.5 mm

Individual characters within the BABSL05 code should not be assigned unsupported technical meanings unless explicitly defined by CORTECO for the exact product.

Additional dust lip

CORTECO 01033389B incorporates an:

additional dust lip

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

Depending on the operating environment, this can include:

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

The additional dust lip is an important construction characteristic when CORTECO 01033389 is compared with potential alternatives.

CORTECO 01033389 and VOLVO 11999321

A confirmed OE reference associated with this seal is:

VOLVO 11999321

The reference relationship is:

CORTECO 01033389 / 01033389B

CORTECO 82033389

VOLVO 11999321

The OE reference provides an important basis for identifying the correct seal.

The exact installation position and machine configuration should still be verified before ordering.

Agricultural machinery applications

Application data associates CORTECO 01033389B with specified agricultural tractor and machinery configurations from manufacturers including CASE IH, Ford and New Holland.

Catalogue applications include selected models within families such as:

• CASE IH MXM
• Ford 8160, 8260, 8360 and 8560
• New Holland M
• New Holland TM

Selected catalogue listings include MXM120, MXM130, MXM140, MXM155, MXM175 and MXM190, as well as TM115, TM120, TM125, TM130, TM135, TM140, TM150, TM155, TM165, TM175 and TM190.

These model families should not be interpreted as confirmation of compatibility with every version or installation position.

For reliable selection, verify the part number, machine configuration and exact sealing position.

CORTECO 01033389 vs a standard 28x40x6 oil seal

Matching the basic:

28x40x6 mm

dimensions alone does not confirm full technical interchangeability.

The complete specification of CORTECO 01033389 is:

FPM BABSL05 28x40x6/6.5 mm

Other relevant characteristics include:

• FPM material
• BABSL05 profile
• complete 6/6.5 mm axial geometry
• additional dust lip
• requirements of the exact installation position

A standard 28x40x6 radial shaft oil seal should therefore not automatically be considered an equivalent.

Why is the 6/6.5 mm dimension important?

CORTECO specifies two axial values for this product:

6 mm

and:

6.5 mm

The complete size should therefore be written as:

28x40x6/6.5 mm

The 6.5 mm value forms part of the complete geometry of this particular seal construction.

Reducing the product designation to 28x40x6 mm removes information that can be important when identifying the correct part or evaluating interchangeability.

How to select CORTECO 01033389 correctly

The safest starting point is the exact manufacturer reference:

CORTECO 01033389 / 01033389B

or the confirmed OE reference:

VOLVO 11999321

Then verify:

1. inside diameter - 28 mm
2. outside diameter - 40 mm
3. basic axial width - 6 mm
4. additional axial dimension - 6.5 mm
5. FPM material
6. BABSL05 profile
7. additional dust lip
8. exact installation position

Selection and interchangeability checklist

Before ordering, verify:

• CORTECO 01033389 / 01033389B
• CORTECO 82033389
• VOLVO 11999321, where applicable
• d = 28 mm
• D = 40 mm
• B1 = 6 mm
• B2 = 6.5 mm
• FPM material
• BABSL05 profile
• additional dust lip
• construction of the original seal
• exact installation position

Matching the basic dimensions alone does not confirm full technical interchangeability.

Installation of CORTECO 01033389

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

Inspect:

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

Install the seal evenly and squarely using an appropriate installation tool.

Protect the primary sealing lip and additional dust lip against cutting, folding or deformation during installation.

What should be checked if the previous seal was leaking?

If the previous Simmerring was leaking, inspect the surrounding components before installing a new CORTECO 01033389.

Check:

• shaft sealing surface
• wear groove
• shaft runout
• bearing play
• bearing condition
• alignment
• seal housing
• lubricant type and level
• assembly breather, where applicable

Replacing the seal alone may not permanently solve a leak caused by shaft wear, excessive clearance, misalignment or another mechanical fault.
