CORTECO 12011992 NBR COMBI SF4 65x85x13/17 Shaft Seal

Product Overview

CORTECO 12011992 NBR COMBI SF4 65x85x13/17 is a specialized COMBI radial shaft seal designed for demanding rotating-shaft applications, particularly in agricultural machinery and drive assemblies.

The seal has a 65 mm shaft diameter, 85 mm housing diameter and 13/17 mm stepped overall construction. It is manufactured from NBR (Nitrile Butadiene Rubber) and is cross-referenced with GOLDONI 6220165 / 06220165. Available catalogue data also identifies 12011992B as a corresponding CORTECO reference.

COMBI SF4 Seal Design

The COMBI SF4 designation identifies a specialized sealing configuration intended for applications where the shaft sealing position requires more protection than a conventional single-lip radial oil seal.

COMBI-type seals combine the primary lubricant-sealing function with additional protection of the sealing area against external contamination. This makes this type particularly relevant to agricultural machinery, transmissions, axles and drive assemblies exposed to dirt and demanding operating environments.

For replacement purposes, the complete COMBI SF4 construction should be matched rather than selecting a conventional 65x85 radial shaft seal based only on its basic diameters.

Dimensions 65x85x13/17 mm

Catalogue dimensions for CORTECO 12011992 / 12011992B are:

Shaft Diameter: 65 mm
Housing Diameter: 85 mm
Width H: 13 mm
Overall / Secondary Height H1: 17 mm
Material: NBR
Design: COMBI SF4
Weight: approximately 0.10 kg

The 13/17 mm configuration is an important identification feature and must be considered when selecting a replacement.

NBR Sealing Material

The seal is manufactured from NBR (Nitrile Butadiene Rubber). NBR is widely used in shaft sealing applications because of its good resistance to many mineral oils and lubricating greases and its useful mechanical properties.

Product data for this specific seal identifies NBR as the sealing material and lists an operating range of approximately -40°C to +100°C, with short-term exposure up to +120°C. Actual suitability depends on the lubricant, shaft speed and operating conditions.

GOLDONI 6220165 Cross Reference

One of the most important identification features of this CORTECO seal is its association with GOLDONI agricultural machinery.

Relevant catalogue references include:

CORTECO: 12011992
CORTECO: 12011992B
GOLDONI: 6220165
GOLDONI: 06220165

The GOLDONI reference 6220165 is directly associated with the 65x85x13/17 COMBI seal.

Additional cross-reference data also associates this seal with Lombardini 38100214 and Maschio 495M38100214R, expanding its identification in agricultural equipment applications.

Agricultural Machinery Applications

CORTECO 12011992 COMBI SF4 is particularly relevant to agricultural machinery where rotating shafts operate in environments exposed to dust, soil and other external contamination.

Cross-reference catalogues associate the seal with:

• GOLDONI agricultural machinery
• MASCHIO equipment
• LOMBARDINI applications
• agricultural drive systems
• transmission assemblies
• rotating shafts and axles

Compatibility should be confirmed using the OE number, original seal reference and installation dimensions, rather than machine brand alone.

Replacement Identification

When replacing CORTECO 12011992, verify:

• CORTECO 12011992 or 12011992B reference
• 65 mm shaft diameter
• 85 mm housing diameter
• 13/17 mm installation dimensions
• NBR material
• COMBI SF4 construction
• GOLDONI 6220165 / 06220165 reference
• exact installation position

A conventional 65x85 oil seal should not automatically be considered a replacement. The COMBI SF4 construction and 13/17 mm geometry are important parts of the product specification.

Operational Advantages

• Specialized COMBI SF4 construction.
• Exact 65x85x13/17 mm dimensions.
• NBR sealing material.
• Designed for rotating shaft applications.
• Additional protection for contaminated working environments.
• Direct cross-reference to GOLDONI 6220165.
