CORTECO 12019930 165x190x15.5/16.5 NBR RWDR-K7 S2 Wheel Hub Seal

CORTECO 12019930 - Product Characteristics

CORTECO 12019930, catalogued as 12019930B, is an NBR wheel hub shaft seal with dimensions 165x190x15.5/16.5 mm. The exact design / trade designation is RWDR-K7 S2 Simmerring. The seal has a 165 mm inside diameter, 190 mm outside diameter and two specified axial dimensions of 15.5 and 16.5 mm.

The exact reference is catalogued for wheel hub sealing applications and is associated with LANDINI OE 3696866M2 and NEW HOLLAND OE 87309584 and 84251055. The additional CORTECO trade number is 82019930, and the EAN is 3358960480637.

Dimensions

Verified dimensional data for CORTECO 12019930B:

Inside Diameter: 165 mm
Outside Diameter: 190 mm
Width / Height 1: 15.5 mm
Width / Height 2: 16.5 mm
Complete Size: 165x190x15.5/16.5 mm
Material: NBR - Nitrile Butadiene Rubber
Design / Profile: RWDR-K7 S2
Trade Designation: RWDR-K7 S2 Simmerring
Additional CORTECO Number: 82019930
EAN: 3358960480637

For this exact reference, the complete 15.5/16.5 mm axial dimension is technically relevant. The product should therefore not be reduced to a generic 165x190x15.5 mm seal when identifying or comparing it.

RWDR-K7 S2 Construction

The specified construction for CORTECO 12019930B is RWDR-K7 S2.

Technical seal catalogues classify this configuration as a cassette-type shaft seal. A cassette seal differs structurally from a simple conventional radial shaft seal because the complete sealing arrangement incorporates additional structural elements as an integrated assembly.

This distinction is important when identifying CORTECO 12019930B. A conventional radial oil seal with the same 165 mm shaft diameter and 190 mm housing diameter should not automatically be considered equivalent.

The suffix S2 is retained as an integral part of the exact CORTECO design designation. It should not be omitted when searching for or technically comparing this reference.

NBR Material

CORTECO 12019930B is manufactured from NBR (Nitrile Butadiene Rubber).

The material forms part of the technical specification and should be considered together with the dimensions and RWDR-K7 S2 construction when selecting a replacement.

A seal manufactured from another elastomer should not automatically be treated as equivalent solely because its dimensions correspond to 165x190x15.5/16.5 mm.

No specific operating temperature range or detailed chemical-resistance limits are assigned here because these values were not confirmed for this exact CORTECO execution.

Wheel Hub Application

The exact 12019930B reference is catalogued as a shaft seal for the wheel hub. It also appears in agricultural spare-parts catalogues in final-drive sealing applications.

For clear technical identification, appropriate English product terms include:

wheel hub seal
wheel hub shaft seal
cassette shaft seal
RWDR-K7 S2 seal

Compatibility with a specific tractor or machine should be established through the OE reference and the equipment manufacturer's parts catalogue rather than dimensions alone.

LANDINI and NEW HOLLAND OE References

The following OE references are associated with CORTECO 12019930B:

LANDINI: 3696866M2
NEW HOLLAND: 87309584
NEW HOLLAND: 84251055

These references provide an important additional identification criterion, particularly because seals with the same shaft and housing diameters may use different materials or sealing constructions.

Selection and Interchangeability

A generic 165x190 mm oil seal should not automatically be considered a replacement for CORTECO 12019930B.

For technical interchange, compare:

• CORTECO reference 12019930 / 12019930B
• 165 mm inside diameter
• 190 mm outside diameter
• 15.5 mm first axial dimension
• 16.5 mm second axial dimension
• NBR material
• RWDR-K7 construction
• S2 variant
• cassette-type configuration
• wheel hub / final-drive installation position
• applicable LANDINI or NEW HOLLAND OE number

Matching only the inside and outside diameters is insufficient to establish technical interchangeability.
