CORTECO 01031063 100x125x10/14.5 NBR BADUOX7 Radial Shaft Seal

CORTECO 01031063 is an NBR radial shaft seal with BADUOX7 design and dimensions 100x125x10/14.5 mm. The nominal shaft diameter is 100 mm, the outside diameter is 125 mm, and the seal uses a 10/14.5 mm height configuration. CORTECO catalogues associate this exact reference with JOHN DEERE, while the corresponding OE reference is RE23143. Current catalogues also identify the product as 01031063B / 82031063.

CORTECO 01031063 - Product Characteristics

The CORTECO dimensional catalogue identifies the exact reference as:

Reference: 01031063
Material: NBR
Design: BADUOX7
Size: 100x125x10/14.5 mm
Catalogue Application: JOHN DEERE

This is therefore a specific radial shaft seal configuration and should not be identified only by the 100 mm and 125 mm diameters.

The full dimensions, NBR material and BADUOX7 design are all relevant when matching this exact product.

Current aftermarket catalogues identify the corresponding version as CORTECO 01031063B, with trade number 82031063 and design designation BADUOX7 Simmerring.

Dimensions

The verified dimensions are:

Nominal Shaft / Inner Diameter: 100 mm
Outside Diameter: 125 mm
Basic Seal Width / Height: 10 mm
Additional Overall Height: 14.5 mm
Commercial Size: 100x125x10/14.5 mm

The 10/14.5 mm dimension is technically important and should not be simplified to 100x125x10 mm when identifying this CORTECO reference.

The corresponding official John Deere RE23143 specification confirms:

Shaft Diameter: 100 mm
Seal Outer Diameter: 125 mm
Width: 10 mm

This supports the principal dimensional match between the CORTECO reference and the John Deere OE number.

BADUOX7 Seal Construction

The exact CORTECO design designation is BADUOX7.

This design code is an important part of the technical identification of 01031063 and should be considered when comparing the seal with other 100x125 mm products.

For the corresponding JOHN DEERE RE23143 OE seal, John Deere specifies:

Lip Design: Dual Lip
Spring: Garter Spring

The dual-lip configuration means that more than one lip function is incorporated into the seal design, while the garter spring provides controlled radial loading of the primary sealing lip.

For replacement selection, the BADUOX7 profile should therefore be considered alongside the dimensions and material.

NBR Material

CORTECO 01031063 BADUOX7 is manufactured from NBR, or nitrile butadiene rubber.

The NBR material is explicitly listed in the CORTECO dimensional catalogue for this exact reference.

Material should be treated as a technical selection parameter. A 100x125x10/14.5 seal manufactured from another elastomer should not automatically be treated as identical to the NBR BADUOX7 version.

No exact operating-temperature range is assigned here to CORTECO 01031063 because a generic NBR range does not prove the approved operating limits of this exact seal compound and application.

CORTECO 01031063 and JOHN DEERE RE23143

The relationship with John Deere is directly supported by catalogue data.

CORTECO lists:

01031063 - NBR - BADUOX7 - 100x125x10/14.5 - JOHN DEERE

Current cross-reference catalogues associate the corresponding 01031063B product with:

JOHN DEERE OE RE23143

The official John Deere catalogue identifies RE23143 as an Internal Oil Seal and confirms the 100 mm shaft diameter, 125 mm outer diameter, 10 mm width, dual-lip design and garter spring.

This provides a strong technical basis for the cross-reference between the CORTECO product and John Deere OE number.

Agricultural Machinery Application

CORTECO directly associates 01031063 BADUOX7 with JOHN DEERE in its dimensional catalogue.

The OE reference RE23143 is an original John Deere identification number for an internal oil seal.

This does not mean that the seal should be assumed to fit every John Deere agricultural machine. Final application verification should be based on the exact OE number, machine model, assembly information or serial-number-specific parts catalogue.

Where the John Deere parts documentation specifies RE23143, CORTECO 01031063 / 01031063B can be identified through that cross-reference.

Product and OE References

The following identifiers are associated with this product:

CORTECO: 01031063
CORTECO: 01031063B
CORTECO Trade Number: 82031063
CORTECO Design: BADUOX7 Simmerring
JOHN DEERE OE: RE23143
EAN: 3358960134400

The reference 01031063 appears in the CORTECO dimensional catalogue, while 01031063B is used in current aftermarket catalogues.

For precise product identification, both references are useful, but 01031063 remains the primary designation for this product page.

Selection and Interchangeability

A replacement for CORTECO 01031063 should not be selected from dimensions alone.

The following parameters should be compared:

• nominal shaft diameter: 100 mm,
• outside diameter: 125 mm,
• full height configuration: 10/14.5 mm,
• NBR material,
• BADUOX7 design,
• lip configuration,
• garter spring where OE-equivalent construction is required,
• JOHN DEERE OE RE23143,
• exact installation position in the machine.

A generic 100x125x10 oil seal should therefore not automatically be considered a technical replacement for this CORTECO product.

Installation Considerations

Before installation, inspect the shaft contact surface and seal housing for wear, corrosion, scoring or contamination.

The seal should be installed evenly without deforming the body or damaging the sealing lips.

The sealing lip must not be cut, folded or rolled during assembly.

Correct orientation must follow the design of the machine assembly. When replacing JOHN DEERE RE23143, the installation instructions for the specific John Deere machine or component should take priority over generic radial shaft seal guidance.
