CORTECO 19019968 NBR BASF 28.5x43x6.5 mm Rotary Shaft Seal

CORTECO 19019968 NBR BASF 28.5x43x6.5 mm Rotary Shaft Seal

CORTECO 19019968 is an NBR radial rotary shaft seal with a BASF profile and dimensions 28.5x43x6.5 mm. The manufacturer reference, NBR material, BASF design and exact dimensions are the key identification parameters when selecting a replacement seal. The product can also be found commercially under the reference 19019968B.

Technical Data - CORTECO 19019968

Dimensions

The complete dimensions of CORTECO 19019968 are:

28.5x43x6.5 mm

where:

• 28.5 mm - inside diameter

• 43 mm - outside diameter

• 6.5 mm - seal width

The unusual 28.5 mm inside diameter is an important identification parameter.

A 28 mm or 29 mm seal should not automatically be considered a replacement for the specified 28.5 mm version.

BASF Profile

CORTECO specifies the construction profile as:

BASF

BASF is the profile designation associated with this particular CORTECO seal design.

When selecting a replacement, both dimensions and construction should be considered.

The safest identification is therefore:

CORTECO 19019968 + NBR + BASF + 28.5x43x6.5 mm

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

NBR Material

CORTECO 19019968 is manufactured from:

NBR - nitrile butadiene rubber

NBR is one of the most widely used elastomers in rotary shaft sealing technology.

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 or chemical.

For unusual oils, lubricants or other operating media, compatibility should be verified for the actual application.

A specific temperature range should not be assigned to CORTECO 19019968 solely on the basis of general NBR properties unless that range has been confirmed for the exact product and operating conditions.

Radial Rotary Shaft Seal

CORTECO 19019968 belongs to the radial rotary shaft seal category.

This type of seal operates between a rotating shaft and a stationary housing.

Its function is to help retain the appropriate lubricant within the mechanical assembly while limiting contamination through the shaft passage.

Actual sealing performance depends on the complete mechanical system, including:

• shaft surface condition

• radial runout

• alignment

• mechanical clearances

• operating medium

• lubrication

• operating conditions

CORTECO 19019968 and 19019968B

Two references may be encountered when searching for this product:

19019968

and

19019968B

For accurate identification, the following technical data should also be verified:

NBR + BASF + 28.5x43x6.5 mm

This helps reduce the risk of selecting an incorrect seal when using different catalogues, ERP systems or supplier databases.

Reference AS12167

The reference:

AS12167

is also associated with the 28.5x43x6.5 mm specification in CORTECO catalogue data.

It can therefore be useful when identifying or searching for the product.

However, a reference number alone should not be used as the sole basis for interchangeability without checking the seal design and technical specification.

Why Dimensions Alone Are Not Enough

Dimensional compatibility is essential when selecting a rotary shaft seal, but dimensions do not provide the complete product specification.

Seals with identical or similar dimensions can differ in:

• elastomer material

• profile

• sealing lip geometry

• outside surface construction

• intended application

• operating characteristics

For this reason, the preferred identification for this product is:

CORTECO 19019968 NBR BASF 28.5x43x6.5 mm

Shaft Inspection Before Installation

Before installing a new seal, inspect the running surface carefully.

Check for:

• wear grooves

• corrosion

• scratches

• sharp edges

• contamination

• mechanical damage

• excessive shaft play

• misalignment

A new seal installed on a damaged running surface may develop leakage prematurely.

Installation

CORTECO 19019968 should be installed evenly and square to the housing bore.

During installation, protect the sealing lip against:

• cutting

• folding

• excessive deformation

• contact with sharp edges

A suitable installation tool should be used to apply force evenly to the appropriate surface of the seal.

Direct hammer blows to the functional sealing components should be avoided.

How to Select the Correct Seal

Before ordering, verify:

1. CORTECO reference - 19019968.

2. Inside diameter - 28.5 mm.

3. Outside diameter - 43 mm.

4. Width - 6.5 mm.

5. Material - NBR.

6. Profile - BASF.

7. Construction of the removed seal.

8. Operating medium and conditions.

Dimensions 28.5x43x6.5 mm alone should not be considered sufficient proof of full interchangeability.

FAQ

What are the dimensions of CORTECO 19019968?

The dimensions are:

28.5x43x6.5 mm

What material is used?

CORTECO specifies:

NBR

What is the profile?

The profile is:

BASF

Is CORTECO 19019968 a rotary shaft seal?

Yes. It is a radial rotary shaft seal.

Is it an oil seal?

Yes. It belongs to the radial shaft seal category commonly referred to in English as a rotary shaft seal or oil seal.

Can the reference 19019968B also be found?

Yes. The product is also encountered commercially under the reference 19019968B.

Is the inside diameter exactly 28.5 mm?

Yes. The specified inside diameter is:

28.5 mm

Can a 28x43x6.5 mm seal replace it?

This should not be assumed. The specified nominal inside diameter is 28.5 mm, and changing this dimension affects the interaction between the sealing lip and shaft.

Can a 29x43x6.5 mm seal be used instead?

It should not automatically be considered interchangeable. The nominal shaft diameter and complete seal specification must match the requirements of the assembly.

Is NBR suitable for oil?

NBR offers good resistance to many mineral oils and greases. Compatibility should nevertheless be verified for the specific lubricant or operating medium.

Is every 28.5x43x6.5 mm oil seal interchangeable with CORTECO 19019968?

No. Material, profile and seal construction should also be verified.

CORTECO 19019968 - Quick Technical Answer

CORTECO 19019968 is an NBR radial rotary shaft seal with a BASF profile and dimensions 28.5x43x6.5 mm. The reference 19019968B is also encountered commercially. Correct selection should consider the complete part number, NBR material, BASF profile and exact dimensions because dimensional similarity alone does not confirm full interchangeability.
