CORTECO 19016587 ACM TBW 40x64x12/17.5 mm

CORTECO 19016587 ACM TBW 40x64x12/17.5 mm - Differential Shaft Seal

CORTECO 19016587 ACM TBW 40x64x12/17.5 mm is a radial rotary shaft seal used in selected automotive drivetrain and differential applications. It is manufactured from ACM (polyacrylate rubber) and features the CORTECO TBW profile. The product is also encountered as CORTECO 19016587B and is catalogued for selected Mazda and Ford applications.

CORTECO 19016587 - Technical Data

What Does CORTECO 19016587 ACM TBW Mean?

The complete designation provides precise identification of this CORTECO shaft seal.

CORTECO - manufacturer and brand specialising, among other product groups, in automotive and industrial sealing technology.

19016587 - CORTECO product reference.

19016587B - reference also encountered in current parts catalogues.

82016587 - trade number associated with the product.

ACM - polyacrylate rubber used as the elastomer material.

TBW - CORTECO profile designation for this specific seal construction.

40x64x12/17.5 mm - nominal geometry comprising a 40 mm inside diameter, 64 mm outside diameter, 12 mm basic width and 17.5 mm overall construction dimension.

The TBW profile is an important part of product identification. Another seal with 40x64 mm diameters should not automatically be considered interchangeable with CORTECO 19016587.

CORTECO 19016587 Dimensions

The nominal dimensions are:

40x64x12/17.5 mm

where:

40 mm - inside diameter

64 mm - outside diameter

12 mm - basic width

17.5 mm - additional overall construction dimension

The 40x64x12/17.5 mm designation indicates a more complex geometry than a conventional shaft seal described by only three dimensions.

The complete 12/17.5 mm dimension is therefore particularly important when identifying an alternative.

A standard 40x64x12 mm seal should not automatically be treated as an equivalent to a 40x64x12/17.5 mm CORTECO TBW seal.

ACM - Polyacrylate Rubber

CORTECO specifies ACM, or polyacrylate rubber, as the elastomer material for reference 19016587.

ACM is used in technical sealing systems, including automotive drivetrain applications operating with compatible oils and lubricants.

However, general ACM properties should not be treated as the exact operating limits of this specific CORTECO seal.

Actual suitability depends on the specific elastomer compound, operating medium, temperature, shaft surface speed and construction of the complete sealing system.

For this reason, no unverified exact temperature, pressure, hardness or rotational speed limits are assigned to CORTECO 19016587.

CORTECO TBW Profile

CORTECO identifies the construction of this seal with the profile designation TBW.

TBW should be treated as an important manufacturer-specific identification characteristic when selecting the product or searching for an alternative.

The individual letters in TBW should not automatically be decoded using another seal manufacturer's nomenclature.

Profile designation systems can differ between manufacturers.

For accurate identification, compare the complete specification:

OE reference

CORTECO 19016587 - Differential Shaft Seal

CORTECO 19016587B is catalogued as a differential shaft seal.

The seal operates within the vehicle drivetrain, separating the lubricated area of the differential or axle assembly from the external environment.

The primary sealing area works against a rotating component, while the outside diameter of the seal is installed in a stationary housing.

Correct sealing performance depends on the condition of the mating surface, correct installation, compatibility of the ACM material with the operating medium and the correct geometry of the entire sealing arrangement.

Mazda Applications

CORTECO catalogues reference 19016587 ACM TBW 40x64x12/17.5 mm for selected Mazda applications.

Associated Mazda OE references include:

MAZDA M00527165

MAZDA M07427623A

Application catalogues associate the product with selected versions of vehicle families including:

Mazda 626 III

Mazda 626 III Station Wagon

Mazda B-Series

A vehicle family name alone does not confirm compatibility with every version.

Different model years, drivetrains, axles and differential configurations can use different seals.

Final selection should therefore be confirmed using the OE reference and exact vehicle specification.

Ford Applications

CORTECO 19016587B is also catalogued for selected Ford applications.

Associated Ford OE references include:

FORD 3647537

FORD XM347048CA

Application catalogues associate the seal with selected versions of:

Ford Ranger

For Ford Ranger applications, the exact vehicle version, drivetrain, axle and OE number should be verified before installation.

OE Numbers for CORTECO 19016587B

Important associated OE references include:

FORD 3647537

FORD XM347048CA

MAZDA M00527165

MAZDA M07427623A

OE references are particularly valuable when identifying automotive seals.

They help distinguish between products that may have similar diameters but different profiles, overall heights, materials or intended applications.

Installation Position

Application catalogues associate CORTECO 19016587B with positions related to the front or rear axle and differential assembly, depending on the specific vehicle.

Some applications may also specify an outer or left-side installation position.

However, an installation position listed for one vehicle should not be assumed to apply to every vehicle using the same CORTECO reference.

The exact location depends on the vehicle, axle design and drivetrain configuration.

CORTECO 19016587 vs Other 40x64 mm Shaft Seals

The basic 40x64 mm diameters are not sufficient to establish interchangeability.

CORTECO offers several seals with the same 40 mm inside diameter and 64 mm outside diameter but different profiles and construction dimensions.

Examples include:

CORTECO 19034980 ACM RHTC9Y 40x64x8/14.5

CORTECO 19035198 ACM RHTC9Y 40x64x9/15.5

CORTECO 19035207 ACM TB9Y 40x64x10/16

CORTECO 19016588 ACM TBSY 40x64x10/16

CORTECO 19016659 ACM TB5Y 40x64x12

CORTECO 19016587 ACM TBW 40x64x12/17.5

These products share the same basic 40x64 mm diameters but differ in profile and geometry.

This demonstrates why the complete designation is essential when selecting a rotary shaft seal.

PAYEN Cross-Reference

Cross-reference catalogues associate CORTECO 19016587B with:

PAYEN NJ813

A cross-reference number can assist with product identification but should not be treated as independent proof of complete technical interchangeability.

Before replacing the CORTECO product with another manufacturer's seal, compare the complete geometry, material, profile and intended application.

Selection and Interchangeability

Before purchasing or replacing CORTECO 19016587 / 19016587B, verify:

• complete CORTECO reference,
• full dimensions 40x64x12/17.5 mm,
• ACM elastomer material,
• TBW profile,
• OE number of the original seal,
• exact installation position,
• axle or differential type,
• drivetrain configuration,
• condition of the mating surface,
• operating lubricant,
• requirements of the specific application.

Identical inside and outside diameters do not automatically mean complete interchangeability.

The full 12/17.5 mm construction dimension is particularly important because CORTECO 19016587 has a defined geometry that cannot be identified from the 40x64 mm diameters alone.

Installation of CORTECO 19016587

Before installation, carefully clean the housing bore and mating surface.

The working surface should be free from corrosion, sharp edges, burrs and deep wear grooves that could damage the seal or cause leakage.

Install the seal squarely and evenly using a suitable installation tool.

Avoid striking or pressing directly on sensitive sealing elements.

Because CORTECO 19016587 has the specific 40x64x12/17.5 mm TBW construction, care should be taken not to damage or deform the extended geometry during installation.

The correct orientation and installation position should also be confirmed for the specific differential or axle assembly.
