CORTECO 01033385 FPM B2VISLSFDRW 80x150x12/20 mm - VOLVO Radial Shaft Oil Seal Simmerring

CORTECO 01033385 FPM B2VISLSFDRW 80x150x12/20 mm is a radial shaft oil seal from the Simmerring family for specified VOLVO construction and working machinery applications. It is manufactured from FPM, features an additional dust lip and an Alternating Twist hydrodynamic sealing structure. The exact dimensions are 80x150x12/20 mm. The catalogue reference is CORTECO 01033385B, while the confirmed VOLVO OE reference is 4717577.

Technical data - CORTECO 01033385

What does CORTECO 01033385 FPM B2VISLSFDRW mean?

The complete technical identification is:

CORTECO 01033385 FPM B2VISLSFDRW 80x150x12/20 mm

CORTECO - manufacturer of the sealing component.

01033385 - base CORTECO product number.

01033385B - catalogue reference associated with this product.

FPM - fluoroelastomer material used for the sealing element.

B2VISLSFDRW - exact profile designation specified for CORTECO 01033385.

80x150x12/20 mm - complete dimensional specification.

Product data also confirms an additional dust lip and an Alternating Twist hydrodynamic sealing structure.

Exact dimensions of CORTECO 01033385

The complete catalogue dimensions are:

80x150x12/20 mm

where:

• d = 80 mm - inside diameter
• D = 150 mm - outside diameter
• B1 = 12 mm - basic axial width
• B2 = 20 mm - additional axial dimension

For technical identification, the complete:

80x150x12/20 mm

designation should be retained.

It should not be simplified to:

80x150x12 mm

because the 20 mm value forms part of the complete geometry of this specific CORTECO seal.

FPM fluoroelastomer

CORTECO specifies the material as:

FPM

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 their material properties are appropriate for the operating environment.

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 01033385 solely from generic FPM 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.

B2VISLSFDRW profile

The exact profile designation is:

B2VISLSFDRW

This profile forms an important part of the technical identity of CORTECO 01033385.

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

FPM + B2VISLSFDRW + 80x150x12/20 mm

Individual characters within the B2VISLSFDRW code should not be assigned unsupported technical meanings unless explicitly defined by CORTECO for this exact product.

Alternating Twist hydrodynamic structure

Product data for CORTECO 01033385B specifies:

Alternating Twist

This refers to a variable hydrodynamic sealing structure incorporated into the sealing system.

Some European catalogues describe this feature as a variable twist or variable thread.

This construction characteristic should be considered when evaluating a technically appropriate replacement.

An Alternating Twist structure should not automatically be treated as equivalent to a seal designed with a single right-hand or left-hand hydrodynamic direction.

Additional dust lip

CORTECO 01033385B features an:

additional dust lip

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

This can be particularly relevant in construction and working machinery exposed to:

• dust
• dirt
• sand
• fine particles
• mud and operating contamination
• moisture

The additional dust lip is therefore an important construction characteristic when comparing CORTECO 01033385 with potential alternatives.

CORTECO 01033385 - VOLVO application

CORTECO catalogue data associates 01033385B with:

VOLVO working / construction machinery

The seal should therefore be identified primarily as a CORTECO sealing component for specified Volvo heavy-equipment applications.

This does not mean that CORTECO 01033385 fits every Volvo construction machine, wheel loader, excavator or other piece of Volvo equipment.

Exact compatibility should be verified using:

• CORTECO product number
• VOLVO OE number
• machine model
• serial number
• exact mechanical assembly
• installation position

CORTECO 01033385 and VOLVO 4717577

The confirmed VOLVO OE reference associated with this product is:

4717577

The reference relationship is:

CORTECO 01033385

CORTECO 01033385B

VOLVO 4717577

The OE number 4717577 provides an important identification route when searching by Volvo technical documentation or by the reference found on the original component.

The exact installation position should still be verified for the specific Volvo machine.

Important note about reference 82033385

The number:

82033385

appears in some aftermarket data associated with CORTECO 01033385B.

However, this number is also used as an official reference for a completely different Case IH / New Holland component.

For unambiguous product identification, it is therefore safer to use:

CORTECO 01033385 / 01033385B

and:

VOLVO 4717577

when identifying this radial shaft oil seal.

This reduces the risk of confusing two unrelated product entities in catalogue searches, procurement systems and online search engines.

CORTECO 01033385 vs a standard 80x150x12 oil seal

Matching the basic dimensions does not confirm complete technical interchangeability.

The full specification of CORTECO 01033385 includes:

FPM + B2VISLSFDRW + 80x150x12/20 mm + additional dust lip + Alternating Twist

When comparing a replacement, verify:

• inside diameter - 80 mm
• outside diameter - 150 mm
• complete 12/20 mm axial geometry
• FPM material
• B2VISLSFDRW profile
• sealing lip construction
• additional dust lip
• hydrodynamic structure
• installation position
• OE reference

A standard 80x150x12 mm radial shaft oil seal should therefore not automatically be considered a replacement for CORTECO 01033385.

Why is the 12/20 mm dimension important?

CORTECO 01033385 has the complete dimensional specification:

80x150x12/20 mm

Both axial values are relevant to the geometry of this particular seal construction:

12 mm

and:

20 mm

When identifying the original seal or evaluating a replacement, both values should therefore be considered.

Reducing the designation to 80x150x12 mm removes part of the information required to identify the specific seal geometry.

How to select CORTECO 01033385 correctly

The safest starting point is the exact manufacturer reference:

CORTECO 01033385 / 01033385B

or the confirmed OE reference:

VOLVO 4717577

Then verify:

1. inside diameter - 80 mm
2. outside diameter - 150 mm
3. basic axial width - 12 mm
4. additional axial dimension - 20 mm
5. FPM material
6. B2VISLSFDRW profile
7. additional dust lip
8. Alternating Twist hydrodynamic structure
9. exact installation position

Selection and interchangeability checklist

Before ordering, verify:

• CORTECO 01033385 / 01033385B
• VOLVO 4717577, where applicable
• d = 80 mm
• D = 150 mm
• B1 = 12 mm
• B2 = 20 mm
• FPM material
• B2VISLSFDRW profile
• additional dust lip
• Alternating Twist
• original seal construction
• exact installation position

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

Installation of CORTECO 01033385

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

Inspect:

• shaft sealing surface
• wear grooves
• scratches and burrs
• corrosion
• housing condition
• alignment
• shaft runout
• bearing play
• condition of mating components

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

Special care should be taken to protect the sealing elements and additional dust lip against cutting, folding or deformation during installation.

What should be checked if the previous seal was leaking?

Before installing a new CORTECO 01033385, inspect:

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

In construction machinery, contamination and the condition of components protecting the seal from the external environment should also be checked.

Replacing the seal alone may not permanently solve leakage if the underlying cause is shaft wear, excessive clearance, misalignment or another mechanical fault.
