GRN KASSETTE 45x70x14/17 NBR Cassette Seal

GRN KASSETTE 45x70x14/17 NBR Cassette Seal

GRN KASSETTE 45x70x14/17 NBR is a cassette-type rotary sealing unit designed for demanding rotating assemblies, particularly axle, wheel hub and drivetrain sealing positions used in agricultural and mobile machinery. It has an inside diameter of 45 mm, outside diameter of 70 mm and width specification of 14/17 mm. A corresponding reference is CORTECO 12015392B with the RWDR-K7 profile.

Technical Data - GRN KASSETTE 45x70x14/17

Dimensions 45x70x14/17 mm

The complete dimensional designation is:

45x70x14/17 mm

where:

• 45 mm - inside diameter
• 70 mm - outside diameter
• 14 mm - basic width of the seal assembly
• 17 mm - additional width dimension associated with the cassette construction

The complete 14/17 mm width designation is important for correct identification and should not be reduced to a single dimension when comparing replacement seals.

What Is a KASSETTE Seal?

KASSETTE refers to a cassette-type sealing construction, which is more complex than a conventional single radial shaft seal.

A cassette seal is an integrated sealing assembly whose individual components are designed to operate together as a complete unit.

This type of construction is particularly useful in demanding mechanical assemblies where the sealing system must help retain lubricant while protecting the sealing area against external contamination.

Cassette Seal vs Conventional Oil Seal

A conventional radial shaft seal normally operates directly against a prepared shaft surface.

A cassette seal is a more complex integrated sealing system.

For this reason, a cassette seal should not be replaced by a conventional oil seal simply because the 45 mm and 70 mm diameters match.

The replacement should correspond to the required:

• construction
• dimensions
• width
• sealing material
• sealing arrangement
• reference number

NBR Material

GRN KASSETTE 45x70x14/17 uses:

NBR - Nitrile Butadiene Rubber

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

Compatibility should nevertheless be checked for the actual operating medium and conditions.

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

CORTECO 12015392B Reference

An important corresponding reference for the 45x70x14/17 NBR cassette seal is:

CORTECO 12015392B

Additional CORTECO designations associated with this product include:

82015392

and:

RWDR-K7

CORTECO 12015392B is specified as an NBR cassette-type seal with dimensions 45x70x14/17 mm.

OE and Cross-Reference Numbers

The following reference numbers are associated with this 45x70x14/17 mm cassette seal configuration:

These references are particularly useful when identifying a cassette seal because selection should be based on both dimensional and constructional compatibility.

CARRARO 132741

The reference:

CARRARO 132741

is an important OE cross-reference associated with the 45x70x14/17 cassette seal.

If the removed component or machine documentation specifies CARRARO 132741, this number can be used as an important identification criterion when selecting the GRN KASSETTE seal.

CASE IH 247519A1

The corresponding CASE IH reference is:

247519A1

For installation in CASE IH machinery, compatibility should additionally be confirmed for the exact machine model and mechanical assembly.

DANA 3765528M1

The following reference is also associated with this seal:

DANA 3765528M1

This reference can assist in identifying the seal in assemblies incorporating DANA axle or drivetrain components.

MASSEY FERGUSON References

The associated MASSEY FERGUSON references include:

053965R1

3765528M1

3785500M1

Because several reference numbers are associated with this seal, the number from the machine documentation or removed component should be compared carefully before ordering.

POTTINGER 415.900

The POTTINGER reference is:

415.900

The OE number provides an additional identification criterion, particularly in agricultural machinery where similar axle and drivetrain components can be used across different machine models.

Typical Applications of Cassette Seals

Cassette sealing systems of this type are commonly encountered in demanding mechanical assemblies such as:

• axles
• wheel hubs
• drivetrain systems
• final drives
• agricultural machinery assemblies
• construction machinery
• mobile equipment

This does not mean that GRN 45x70x14/17 is universally suitable for every such application.

Dimensional, constructional and reference compatibility must be confirmed.

Why Are Cassette Seals Used in Demanding Environments?

Axle and wheel hub assemblies can operate in environments exposed to:

• dust
• mud
• water
• fine mineral particles
• contamination generated during machine operation

At the same time, the sealing system must help retain lubricant inside the protected assembly.

The integrated cassette construction is designed for sealing positions where protection against external contamination is particularly important.

Why Are 45x70 Dimensions Alone Not Enough?

A cassette seal should never be selected solely on the basis of its two diameters.

The complete designation:

45x70x14/17 mm

contains important information about the dimensions of the sealing assembly.

A conventional seal such as:

45x70x10 mm

or:

45x70x12 mm

should not automatically be considered a replacement for a 45x70x14/17 KASSETTE seal.

How to Select GRN KASSETTE 45x70x14/17

Before ordering, verify:

1. Inside diameter - 45 mm.
2. Outside diameter - 70 mm.
3. Width - 14/17 mm.
4. Construction - KASSETTE.
5. Material - NBR.
6. OE or cross-reference number.
7. Construction of the removed seal.
8. Dimensions and condition of the installation position.

If available, compare the existing part with CARRARO 132741, CASE IH 247519A1, CORTECO 12015392B, DANA 3765528M1, MASSEY FERGUSON 053965R1 / 3765528M1 / 3785500M1 or POTTINGER 415.900.

Inspection Before Installation

Before installing the new cassette seal, thoroughly clean and inspect the complete sealing position.

Check for:

• damaged mating surfaces
• corrosion
• contamination
• bearing condition
• excessive play
• misalignment
• housing damage
• the cause of the previous leakage

Replacing the seal without correcting excessive mechanical play or damaged mating components can result in premature failure.

Installation of a Cassette Seal

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

During installation:

• use a suitable installation tool
• avoid direct impact on functional sealing components
• do not separate the components of the cassette assembly
• keep sealing surfaces clean
• avoid tilting the seal during installation
• follow the installation procedure specified for the particular mechanical assembly

Correct installation is especially important because a cassette seal functions as an integrated sealing unit.
