CORTECO 01002493 NBR B1 30x55x12 mm - Radial Shaft Oil Seal Simmerring FENDT

CORTECO 01002493 NBR B1 30x55x12 mm - Radial Shaft Oil Seal Simmerring FENDT

CORTECO 01002493 NBR B1 30x55x12 mm is a radial shaft oil seal from the Simmerring family, manufactured from NBR nitrile butadiene rubber. The seal has a 30 mm inside diameter, 55 mm outside diameter and 12 mm width. CORTECO identifies this version with the B1 construction. The product is catalogued for FENDT applications, with FENDT OE reference X550215309000 associated with CORTECO 01002493B.

Technical data - CORTECO 01002493

What does CORTECO 01002493 NBR B1 mean?

The complete designation:

CORTECO 01002493 NBR B1 30x55x12 mm

should be considered as a set of parameters identifying this specific radial shaft seal.

CORTECO - manufacturer.

01002493 - catalogue number identifying the specific CORTECO product.

NBR - elastomer material, Nitrile Butadiene Rubber.

B1 - CORTECO construction designation for this seal.

30x55x12 mm - nominal seal dimensions.

All of these parameters should be considered when selecting a replacement. Dimensions alone are not sufficient to establish full interchangeability.

Dimensions of CORTECO 01002493

The nominal dimensions are:

30x55x12 mm

where:

• d = 30 mm - inside diameter
• D = 55 mm - outside diameter
• B = 12 mm - width

These dimensions are associated with CORTECO references 01002493 and 01002493B.

The product should not be identified only as a "30x55x12 oil seal", because seals with the same nominal dimensions can differ in material, construction and intended application.

NBR - Nitrile Butadiene Rubber

CORTECO 01002493 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomer families for radial shaft oil seals. It is commonly used in sealing systems operating with compatible mineral oils, lubricants and greases.

Correct material selection should nevertheless consider:

• operating medium
• operating temperature
• shaft surface speed
• pressure conditions
• lubrication
• shaft surface condition

A universal operating temperature range is intentionally not assigned here to CORTECO 01002493 because the exact limits should be based on manufacturer data for the specific elastomer compound and actual operating conditions.

B1 construction

CORTECO identifies the construction of this seal as:

B1

The construction designation is an important part of product identification.

Therefore:

CORTECO 01002493 NBR B1 30x55x12 mm

provides more precise technical identification than simply:

30x55x12 mm

When selecting an alternative seal, the B1 construction should be compared with the construction of the original component.

A different CORTECO profile with identical 30x55x12 mm dimensions should not automatically be treated as a direct replacement for B1.

CORTECO 01002493 and 01002493B

Two related reference formats can be found in catalogues:

01002493

and:

01002493B

The CORTECO dimensional catalogue identifies the product using reference 01002493, while aftermarket catalogue systems also list:

01002493B

For product identification and cross-reference searches, both formats can therefore be useful.

The base CORTECO product number remains:

01002493

CORTECO 01002493 for FENDT

CORTECO catalogue data associates:

01002493 NBR B1 30x55x12 mm

with:

FENDT

Cross-reference catalogue data additionally connects CORTECO 01002493B with the OE reference:

FENDT X550215309000

This provides a more precise method of product identification than selecting a seal solely according to its 30x55x12 mm dimensions.

FENDT X550215309000

The confirmed OE reference associated with this seal is:

FENDT X550215309000

The catalogue relationship is:

FENDT X550215309000 - CORTECO 01002493B

This OE number can be used when identifying a replacement seal.

Compatibility with a specific tractor, transmission, axle or other assembly should still be verified according to the machine documentation or OE catalogue.

A specific FENDT tractor model should not be assigned solely from the OE number without confirming the exact application.

Alternative designations and reference numbers

Natural identification and search variants include:

• CORTECO 01002493
• 01002493 CORTECO
• CORTECO 01002493B
• 01002493B CORTECO
• CORTECO 01002493 NBR
• CORTECO 01002493 B1
• CORTECO 01002493 NBR B1
• CORTECO 01002493 30x55x12
• CORTECO 01002493 NBR B1 30x55x12
• CORTECO B1 30x55x12
• CORTECO Simmerring 30x55x12
• CORTECO oil seal 30x55x12
• CORTECO radial shaft seal 30x55x12
• FENDT X550215309000
• X550215309000

Confirmed OE reference:

FENDT X550215309000

OE references should be distinguished from alternative ways of writing the CORTECO product designation.

CORTECO 01002493 vs other 30x55x12 oil seals

The dimensions:

30x55x12 mm

are not sufficient to confirm full technical interchangeability.

Another 30x55x12 mm seal can differ in:

• elastomer material
• seal profile
• sealing lip construction
• outside diameter construction
• application
• operating requirements

For this specific SKU, the important identification set is:

CORTECO 01002493 + NBR + B1 + 30x55x12 mm

When the seal is selected for a FENDT application, the OE reference:

X550215309000

provides an additional identification parameter.

CORTECO 01002493 vs FPM 30x55x12

A seal manufactured from FPM should not automatically be considered equivalent to CORTECO 01002493 simply because it has the same dimensions.

NBR and FPM belong to different elastomer families and have different chemical and thermal characteristics.

Material substitution should therefore be based on the operating medium, temperature, shaft conditions and equipment requirements rather than dimensions alone.

CORTECO 01002493 vs another B1 30x55x12 seal

Even when another product is described as:

B1 30x55x12

full interchangeability should still be verified.

Check:

• manufacturer designation
• exact dimensions
• elastomer material
• seal construction
• OE reference
• installation requirements
• operating medium
• machine application

Matching a generic profile description does not independently confirm that two seals are identical in every technical detail.

How to select a replacement for CORTECO 01002493

Before selecting an alternative seal, verify:

• CORTECO reference 01002493 or 01002493B
• FENDT OE reference X550215309000
• 30 mm shaft diameter
• 55 mm housing diameter
• 12 mm width
• NBR material
• B1 construction
• operating medium
• operating temperature
• lubrication conditions
• shaft condition
• requirements of the specific machine or assembly

Identical 30x55x12 mm dimensions do not automatically establish full technical interchangeability.

Confirmed application

Confirmed catalogue information associates CORTECO 01002493 with:

FENDT

and the OE reference:

X550215309000

A specific tractor model or installation position is intentionally not stated without sufficiently reliable catalogue confirmation for that exact application.

This prevents the seal from being incorrectly assigned to a machine using a different version or seal construction.

Installation of CORTECO 01002493

Before installation, thoroughly clean the shaft and seal housing.

Inspect the shaft surface in the sealing lip contact area for:

• scratches
• corrosion
• burrs
• sharp edges
• wear grooves

The sealing lip should be protected against damage from threads, splines and sharp shaft edges during assembly.

Where required, use a suitable installation sleeve or protective tool.

Correct installation method

CORTECO 01002493 should be installed evenly and squarely using an appropriate installation tool.

Do not apply installation force directly to the functional sealing lip.

Before operation, verify:

• correct seal orientation
• correct seating depth
• absence of seal deformation
• condition of the shaft surface
• condition of the housing
• absence of sealing lip damage

Correct installation is essential even when the correct seal reference has been selected.

Why can a new oil seal still leak?

Replacing the radial shaft seal does not always eliminate the original cause of leakage.

The complete sealing system should also be inspected for:

• shaft wear
• excessive runout
• damaged sealing surface
• incorrect installation
• housing damage
• incorrect seal material
• incorrect seal construction

A pronounced wear groove on the shaft can cause leakage even after a new Simmerring has been installed.
