CORTECO 12011196 NBR BASL 65x90x10 mm Rotary Shaft Seal

CORTECO 12011196 NBR BASL 65x90x10 mm Rotary Shaft Seal

CORTECO 12011196 is an NBR radial rotary shaft seal with a BASL profile and dimensions 65x90x10 mm. The seal is cross-referenced with OE numbers from CARRARO, GOLDONI, JCB, JOHN DEERE, MERCEDES-BENZ, MERLO and NEW HOLLAND. Correct identification should be based on the complete CORTECO reference, dimensions, NBR material, BASL profile and the relevant OE number.

Technical Data - CORTECO 12011196

Dimensions

The complete dimensions are:

65x90x10 mm

where:

• 65 mm - inside diameter
• 90 mm - outside diameter
• 10 mm - width

When selecting a replacement, all three dimensions should be checked together with the BASL profile, NBR material and OE reference.

BASL Profile

CORTECO specifies the seal profile as:

BASL

The BASL designation is an important construction characteristic and should not be omitted when comparing alternative seals.

The safest product identification is:

CORTECO 12011196 + NBR + BASL + 65x90x10 mm

A seal with identical dimensions but a different profile should not automatically be considered fully interchangeable.

NBR - Nitrile Butadiene Rubber

CORTECO 12011196 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is widely used in radial shaft sealing technology because of its good resistance to many mineral oils and greases.

Typical advantages of NBR in compatible applications include:

• good resistance to many mineral oils
• good resistance to many lubricating greases
• good mechanical properties
• suitability for numerous conventional rotary shaft sealing applications

Material compatibility should nevertheless be verified against the actual lubricant or operating medium.

A specific temperature range should not be assigned to this exact CORTECO seal solely on the basis of general NBR properties.

Function of a Rotary Shaft Seal

A radial rotary shaft seal operates at the interface between a rotating shaft and a stationary housing.

Its primary functions are to:

• help retain lubricant inside the mechanical assembly
• reduce leakage along the rotating shaft
• help limit the ingress of external contamination
• protect the lubricated mechanical system

Actual sealing performance depends not only on the seal itself but also on shaft condition, alignment, runout, lubrication and the condition of the associated bearings and housing.

OE References

CORTECO 12011196 is cross-referenced with several original equipment numbers.

CARRARO

025278

GOLDONI

06220004

JCB

90407300

JOHN DEERE

ER025278

MERCEDES-BENZ

0029974147

MERLO

024937

NEW HOLLAND

536079

These references are valuable for product identification. Compatibility with a specific machine, axle or vehicle should still be confirmed using the relevant OE parts catalogue.

CORTECO 12011196 for CARRARO

The corresponding CARRARO reference is:

025278

This OE number is particularly useful when identifying the seal in axle and drivetrain parts catalogues.

CORTECO 12011196 for JOHN DEERE

The JOHN DEERE reference is:

ER025278

The similarity between CARRARO 025278 and JOHN DEERE ER025278 can be useful when identifying components used in compatible axle assemblies.

However, compatibility should always be checked for the exact machine and axle configuration.

CORTECO 12011196 for JCB

The corresponding JCB reference is:

90407300

When replacing the seal in JCB equipment, the OE number should be compared with the machine parts documentation before installation.

CORTECO 12011196 for MERCEDES-BENZ

The MERCEDES-BENZ OE reference is:

0029974147

The OE number provides a more precise identification criterion than selecting a seal solely by its 65x90x10 mm dimensions.

CORTECO 12011196 for NEW HOLLAND

The NEW HOLLAND reference associated with the seal is:

536079

The exact machine model and mechanical assembly should be checked before installation.

Why OE Numbers Matter

A rotary shaft seal should not be selected only by its dimensions.

Two seals can both measure:

65x90x10 mm

while differing in:

• profile
• sealing lip construction
• material
• external design
• application
• OE specification

Therefore, when an OE reference is available, it should be used together with the complete CORTECO part number.

Selecting the Correct Replacement

Before ordering CORTECO 12011196, verify:

1. CORTECO part number - 12011196.
2. Inside diameter - 65 mm.
3. Outside diameter - 90 mm.
4. Width - 10 mm.
5. Material - NBR.
6. Profile - BASL.
7. Relevant OE reference.
8. Construction of the removed seal.

Identical 65x90x10 mm dimensions alone do not confirm full interchangeability.

Inspection Before Installation

Before installing the new seal, inspect the complete sealing position.

Check the shaft for:

• wear grooves
• corrosion
• scratches
• mechanical damage
• sharp edges
• contamination

Also check:

• shaft play
• bearing condition
• alignment
• housing condition
• possible cause of the original leakage

Replacing the seal without correcting mechanical wear can result in premature leakage.

Installation

The seal should be installed evenly and square to the housing bore.

During installation:

• protect the sealing lip from sharp edges
• avoid folding or damaging the lip
• use an appropriate installation tool
• apply installation force evenly
• follow the equipment manufacturer's installation procedure

The correct mounting orientation and installation depth should correspond to the design of the specific mechanical assembly.
