Rotary Shaft Seal CORTECO 01031080 FPM B1VISLRS Oil Seal 39,4x52x7/8

CORTECO 01031080 FPM B1VISLRS 39.4x52x7/8 mm - VOLVO TRUCK Radial Shaft Oil Seal Simmerring

CORTECO 01031080 FPM B1VISLRS 39.4x52x7/8 mm is a radial shaft oil seal from the Simmerring family for specified VOLVO TRUCK applications. It is manufactured from FPM fluoroelastomer and features the B1VISLRS profile. The exact catalogue dimensions are 39.4x52x7/8 mm. The product is also referenced as CORTECO 01031080B.

Technical data - CORTECO 01031080

What does CORTECO 01031080 FPM B1VISLRS mean?

The complete technical identification is:

CORTECO 01031080 FPM B1VISLRS 39.4x52x7/8 mm

CORTECO - manufacturer of the sealing component.

01031080 - base CORTECO product number.

01031080B - catalogue reference associated with this product.

FPM - fluoroelastomer material used for the sealing element.

B1VISLRS - exact CORTECO profile designation.

39.4x52x7/8 mm - complete catalogue dimensions.

VOLVO TRUCK - application group identified in CORTECO catalogue data.

Exact dimensions of CORTECO 01031080

The complete catalogue size is:

39.4x52x7/8 mm

where:

• d = 39.4 mm - inside diameter
• D = 52 mm - outside diameter
• B1 = 7 mm - basic axial width
• B2 = 8 mm - additional axial dimension

For technical identification, the complete:

39.4x52x7/8 mm

designation should be retained.

It should not be simplified to:

39.4x52x7 mm

because the 8 mm value forms part of the complete geometry of this specific CORTECO Simmerring.

FPM fluoroelastomer

CORTECO specifies the material as:

FPM

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

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

Correct seal selection should take into account:

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

A specific operating temperature range should not be assigned to CORTECO 01031080 solely from generic FPM material properties. Actual limits depend on the exact compound and application conditions.

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

B1VISLRS profile

The exact profile designation for this product is:

B1VISLRS

This code forms an integral part of the technical identity of CORTECO 01031080.

When evaluating a potential equivalent, the complete combination should therefore be considered:

FPM + B1VISLRS + 39.4x52x7/8 mm

Individual characters within B1VISLRS should not be assigned unsupported technical meanings unless explicitly defined by CORTECO for this exact product.

CORTECO 01031080 - VOLVO TRUCK application

CORTECO catalogue data associates:

01031080B

with:

VOLVO TRUCK

The seal is therefore catalogued for specified Volvo commercial-vehicle applications.

Aftermarket application catalogues also identify CORTECO 01031080B as a crankshaft oil seal in Volvo applications.

This should not, however, be interpreted as confirmation that the seal fits every Volvo truck, engine or engine version.

Before ordering, verify:

• original seal reference
• exact installation position
• complete dimensions
• seal profile
• engine or assembly version
• OE reference, if available for the specific vehicle

Why is the 39.4 mm diameter important?

The exact inside diameter of CORTECO 01031080 is:

39.4 mm

It should not automatically be rounded to:

39 mm

or:

40 mm

The shaft diameter is a critical parameter in radial shaft seal selection.

Even a relatively small dimensional difference may affect the interaction between the sealing lip and shaft surface.

For this reason, searches for a generic 40x52x7 oil seal should not be treated as equivalent to an exact search for CORTECO 01031080.

Why is the 7/8 mm dimension important?

The complete axial geometry is specified as:

7/8 mm

The correct full size is therefore:

39.4x52x7/8 mm

Reducing the designation to 39.4x52x7 mm removes part of the dimensional information describing this particular seal construction.

This can be especially important when comparing seals with identical or very similar primary diameters.

Alternative designations and reference numbers

Confirmed CORTECO references:

• 01031080
• 01031080B

A specific VOLVO OE number should not be assigned to this product without reliable confirmation for the exact CORTECO reference.

CORTECO 01031080 vs a standard 40x52x7 oil seal

A standard:

40x52x7 mm

oil seal should not automatically be considered an alternative to CORTECO 01031080.

The exact CORTECO specification is:

FPM B1VISLRS 39.4x52x7/8 mm

Important differences to verify include:

• exact 39.4 mm inside diameter
• 52 mm outside diameter
• complete 7/8 mm axial geometry
• FPM material
• B1VISLRS profile
• sealing construction
• exact installation requirements

A difference between 39.4 mm and 40 mm should not be ignored when selecting a radial shaft oil seal.

How to select CORTECO 01031080 correctly

The safest starting point is the exact manufacturer reference:

CORTECO 01031080

or:

CORTECO 01031080B

Then verify:

1. inside diameter - 39.4 mm
2. outside diameter - 52 mm
3. basic axial width - 7 mm
4. additional axial dimension - 8 mm
5. FPM material
6. B1VISLRS profile
7. construction of the original seal
8. exact installation position
9. Volvo vehicle, engine or assembly version

Selection and interchangeability checklist

Before ordering, verify:

• CORTECO 01031080 / 01031080B
• d = 39.4 mm
• D = 52 mm
• B1 = 7 mm
• B2 = 8 mm
• FPM material
• B1VISLRS profile
• original seal construction
• VOLVO TRUCK application
• exact installation position

Matching or similar basic dimensions do not automatically confirm full technical interchangeability.

Installation of CORTECO 01031080

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 Simmerring evenly and squarely using an appropriate installation tool.

Protect the sealing elements 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 assembly before installing a new CORTECO 01031080.

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 leakage caused by shaft wear, excessive clearance, misalignment or another mechanical fault.
