CORTECO 19037034 49.5x100/105x25 NBR RWDR-K7 Wheel Hub Seal JOHN DEERE RE185799

CORTECO 19037034 49.5x100/105x25 NBR RWDR-K7 Wheel Hub Seal JOHN DEERE RE185799

CORTECO 19037034 / 19037034B is an NBR rotary shaft seal for a wheel hub, manufactured in the RWDR-K7 design with dimensions of 49.5x100/105x25 mm. The seal has a 49.5 mm inside diameter, two outside diameters of 100 mm and 105 mm, and a height of 25 mm.

A key cross-reference for this product is JOHN DEERE RE185799, making the OE number particularly important when identifying the correct wheel hub seal for JOHN DEERE agricultural machinery.

CORTECO 19037034 – characteristics

The key confirmed identification data are:

• Trade number: 82037034
• Seal design: RWDR-K7
• Product type: Rotary shaft seal
• Application: Wheel hub
• Inside diameter: 49.5 mm
• Outside diameter: 100 mm
• Additional outside diameter: 105 mm
• Height: 25 mm
• Material: NBR

• JOHN DEERE OE reference: RE185799

Dimensions of CORTECO 19037034

This wheel hub seal has a characteristic stepped external geometry with two outside diameters.

The complete dimension should be retained as:

49.5x100/105x25 mm

It should not be simplified to 49.5x100x25 mm because the additional 105 mm outside diameter is an important part of the seal geometry.

RWDR-K7 seal design

CORTECO identifies this seal with the construction designation:

RWDR-K7

This designation is important when identifying an equivalent because the dimensions alone do not fully describe the geometry and functional design of the seal.

A standard radial shaft seal with similar basic diameters should therefore not automatically be considered interchangeable with an RWDR-K7 wheel hub seal.

NBR – Nitrile Butadiene Rubber

CORTECO 19037034 is manufactured from NBR – Nitrile Butadiene Rubber, commonly referred to as nitrile rubber.

NBR is widely used in sealing technology, particularly for components operating in contact with many mineral oils and greases.

For this exact CORTECO reference, NBR is part of the product specification. Material should therefore be considered together with dimensions, seal geometry and OE reference when evaluating an alternative.

JOHN DEERE wheel hub seal

CORTECO 19037034B is catalogued as a:

shaft seal, wheel hub

with an outer installation position.

In a wheel hub assembly, the sealing system separates the lubricated working area from the external environment. It helps retain lubricant while restricting the ingress of dirt and other contaminants into the protected assembly.

Correct installation and compatibility with the specific hub design remain essential.

CORTECO 19037034 and JOHN DEERE RE185799

The principal OE reference associated with this seal is:

JOHN DEERE RE185799

This is especially useful when searching international parts catalogues, workshop inventories and replacement-part databases.

The product may therefore be encountered under search combinations such as:

JOHN DEERE RE185799 wheel hub seal
RE185799 oil seal
RE185799 rotary shaft seal
RE185799 hub seal
CORTECO 19037034
CORTECO 19037034B
19037034 RE185799
19037034B RE185799
RWDR-K7 49.5x100/105x25
49.5x100/105x25 NBR seal

These variations help identify the exact reference without changing the actual product designation.

Applications in JOHN DEERE machinery

Replacement-parts catalogues associate CORTECO 19037034B / JOHN DEERE RE185799 with a range of JOHN DEERE agricultural machines.

References can be found for machines from several JOHN DEERE tractor families, including selected models from the 8000, 8010, 8020 and 8030 generations and some later 7R and 8R applications.

However, machine model alone should not be used as definitive proof of fitment.

Depending on production year, axle configuration and machine specification, different seals may be fitted to apparently similar tractors.

The safest identification method is to confirm JOHN DEERE OE number RE185799 against the parts documentation for the specific machine.

CORTECO 19037034 or 19037034B?

The reference can be encountered in two forms:

19037034

and

19037034B

Older CORTECO/TG Ersatzteile catalogue data identify the product as 19037034, while more recent aftermarket catalogues commonly use 19037034B.

The associated technical identification remains:

NBR – RWDR-K7 – wheel hub – 49.5x100/105x25 mm – JOHN DEERE RE185799

For inventory, invoicing and ordering, the number shown on the current CORTECO packaging or current manufacturer documentation should take precedence.

19037034 vs standard oil seals

This product should not be selected solely by comparing its 49.5 mm shaft diameter with a conventional oil seal.

CORTECO 19037034 has:

• RWDR-K7 construction,
• stepped 100/105 mm external geometry,
• 25 mm overall height,
• NBR material,
• wheel hub application,
• specific JOHN DEERE OE cross-reference.

These characteristics provide a much more precise identification than the shaft diameter alone.

Selecting an equivalent for CORTECO 19037034

When evaluating an equivalent, verify:

1. JOHN DEERE OE reference RE185799,
2. seal design RWDR-K7,
3. inside diameter 49.5 mm,
4. first outside diameter 100 mm,
5. second outside diameter 105 mm,
6. height 25 mm,
7. NBR material,
8. outer installation position,
9. wheel hub and axle configuration,
10. documentation for the specific JOHN DEERE machine.

Matching only the basic dimensions does not establish full interchangeability.

The RWDR-K7 construction and stepped 100/105 mm outside geometry are particularly important.

Are CORTECO 19037034 and 19037034B the same reference?

The older reference 19037034 and the newer 19037034B are associated in catalogue data with the same 49.5x100/105x25 mm NBR RWDR-K7 wheel hub seal and JOHN DEERE RE185799 identification.

Can this seal be selected by dimensions alone?

No. In addition to 49.5x100/105x25 mm, the RWDR-K7 construction, NBR material, OE reference and compatibility with the specific hub assembly should be verified.

Does CORTECO 19037034 fit every JOHN DEERE tractor?

No. Fitment should be confirmed using OE reference RE185799 and the parts documentation for the specific machine, axle and configuration.
