CORTECO 12011344 NBR B1 105x125x12 mm Rotary Shaft Seal

CORTECO 12011344 NBR B1 105x125x12 mm Rotary Shaft Seal

CORTECO 12011344 is an NBR rotary shaft seal with a B1 profile and dimensions 105x125x12 mm. The CORTECO dimensional catalogue associates this reference with NEW HOLLAND applications. The complete part number 12011344, B1 profile, NBR material and exact dimensions are the key identification parameters when selecting or replacing this radial shaft seal.

Technical Data - CORTECO 12011344

Dimensions

The complete dimensions of CORTECO 12011344 are:

105x125x12 mm

where:

• 105 mm - inside diameter

• 125 mm - outside diameter

• 12 mm - seal width

Dimensions are an essential selection criterion, but they should not be used as the only basis for determining interchangeability.

B1 Profile

CORTECO specifies the seal profile as:

B1

B1 is the manufacturer's construction designation and should be considered when identifying a replacement seal.

The safest identification is based on the complete specification:

CORTECO 12011344 + NBR + B1 + 105x125x12 mm

A different rotary shaft seal with the same 105x125x12 mm dimensions should not automatically be considered equivalent.

Seals with identical dimensions can differ in material, profile and construction.

NBR Material

CORTECO 12011344 is manufactured from:

NBR - nitrile butadiene rubber

NBR is one of the most widely used elastomers for rotary shaft sealing applications.

It provides good resistance to many:

• mineral oils

• mineral greases

• commonly used lubricants

• media compatible with nitrile rubber

However, NBR is not universally compatible with every fluid.

For unusual lubricants, hydraulic fluids or other media, material compatibility should be verified for the actual operating conditions.

A specific operating temperature range should not be assumed solely from the general properties of NBR. Actual seal performance also depends on shaft speed, lubrication, medium and the complete sealing arrangement.

Rotary Shaft Seal Function

CORTECO 12011344 belongs to the group of radial rotary shaft seals.

Its primary function is to seal the interface between:

a rotating shaft

and

a stationary housing.

A correctly selected rotary shaft seal helps retain the appropriate lubricant within the mechanical assembly and limits contamination through the shaft passage.

Actual sealing performance depends on the complete system, including shaft condition, alignment, speed, lubrication and environmental conditions.

NEW HOLLAND Application

The CORTECO dimensional catalogue associates part number:

12011344

with:

NEW HOLLAND

This is useful identification information, but the machine manufacturer alone is not sufficient to confirm compatibility.

NEW HOLLAND includes many machines, models and mechanical assemblies.

Before installation, compatibility should therefore be confirmed using available information such as:

• CORTECO part number

• OE reference, where available

• machine model

• machine serial number

• assembly type

• dimensions of the removed seal

• seal profile

CORTECO 12011344 should not be assigned to a specific NEW HOLLAND model without confirmation in the appropriate parts catalogue.

CORTECO 12011344 vs Other 105x125x12 Seals

Other CORTECO rotary shaft seals can exist with the same dimensions:

105x125x12 mm

but with different materials or profiles.

This means:

dimensions alone do not uniquely identify a rotary shaft seal.

Two seals can have identical:

• inside diameter

• outside diameter

• width

while differing in:

• elastomer material

• seal profile

• lip construction

• application

• operating characteristics

For this reason, the complete reference should be used:

CORTECO 12011344 NBR B1 105x125x12 mm

NBR vs FPM/FKM

Rotary shaft seals with dimensions 105x125x12 mm may also be available in FPM/FKM material.

This does not automatically make them interchangeable.

NBR

Nitrile rubber offers good compatibility with many common mineral oils and greases and is widely used in conventional mechanical sealing applications.

FPM/FKM

Fluoroelastomer is selected where different thermal or chemical resistance characteristics are required.

Material selection should correspond to the requirements of the actual machine and sealing position.

An NBR seal should not automatically be replaced by an FPM/FKM seal, or vice versa, simply because the dimensions are identical.

How to Select CORTECO 12011344

The most reliable identification criterion is the manufacturer's part number:

12011344

If the number on the removed seal cannot be identified, check:

1. Shaft diameter - 105 mm.

2. Housing bore diameter - 125 mm.

3. Seal width - 12 mm.

4. Profile - B1.

5. Material - NBR.

6. Machine application.

7. OE reference, if available.

8. Construction of the removed seal.

Matching 105x125x12 mm dimensions alone does not confirm full interchangeability.

Shaft Inspection Before Installation

Before fitting a new rotary shaft seal, inspect the shaft surface where the sealing lip operates.

Check for:

• wear grooves

• corrosion

• scratches

• sharp edges

• contamination

• mechanical damage

• excessive shaft play

A damaged running surface can cause premature wear or leakage even when the correct new seal is installed.

Installation

The sealing lip should be protected from damage during installation.

The seal should be installed:

• evenly

• square to the housing bore

• with a suitable installation tool

• without direct impact on sensitive sealing components

The machine manufacturer's instructions should also be followed regarding installation depth, lubrication and preparation of the shaft surface.

FAQ

What are the dimensions of CORTECO 12011344?

The dimensions are:

105x125x12 mm

What material is used?

The specified material is:

NBR

What is the profile of CORTECO 12011344?

CORTECO specifies:

B1

Is CORTECO 12011344 a rotary shaft seal?

Yes. It is a radial rotary shaft seal.

Is it a Simmerring?

The product belongs to the radial shaft seal category commonly referred to as an oil seal or Simmerring.

Which machine manufacturer is associated with 12011344?

The CORTECO dimensional catalogue indicates:

NEW HOLLAND

Does 12011344 fit every NEW HOLLAND machine?

No. Compatibility must be confirmed for the exact machine model and mechanical assembly.

Is every 105x125x12 mm seal interchangeable with 12011344?

No. Material, profile, construction and application must also be checked.

Is NBR resistant to oil?

NBR provides good resistance to many mineral oils and greases. Compatibility with the actual lubricant or medium should nevertheless be verified.

Can an FKM seal with the same dimensions replace 12011344?

Interchangeability should not be assumed. Identical dimensions do not guarantee the same profile, construction or application requirements.

CORTECO 12011344 - Quick Technical Answer

CORTECO 12011344 is an NBR radial rotary shaft seal with a B1 profile and dimensions 105x125x12 mm. The CORTECO dimensional catalogue associates this reference with NEW HOLLAND applications. Selection should be based on the complete 12011344 reference, NBR material, B1 profile and dimensions because another 105x125x12 mm seal is not automatically interchangeable.
