CORTECO 19016578 ACM TC9 Oil Seal 35x56x9/14.8 mm Simmerring

CORTECO 19016578 ACM TC9 35x56x9/14.8 mm is a radial shaft oil seal manufactured from ACM polyacrylate rubber. It features the TC9 construction, an additional dust lip and a compound axial dimension of 9/14.8 mm. The seal is catalogued for specific drivetrain, axle and differential applications associated with HONDA, HYUNDAI, MAZDA and MITSUBISHI OE references.

Technical data - CORTECO 19016578

CORTECO 19016578 - precise product identification

The complete designation is:

CORTECO 19016578 ACM TC9 35x56x9/14.8 mm

This identifies the product much more precisely than the basic 35x56 mm dimensions alone.

When selecting this seal or a replacement, verify:

• CORTECO part number 19016578
• ACM material
• TC9 construction
• 35 mm inside diameter
• 56 mm outside diameter
• 9/14.8 mm axial dimensions
• additional dust lip
• installation position
• corresponding OE reference
• operating conditions

The full 9/14.8 mm dimension is particularly important. CORTECO 19016578 should not be reduced to a generic 35x56x9 oil seal when searching for a technically suitable replacement.

Dimensions of CORTECO 19016578

The nominal dimensions are:

35x56x9/14.8 mm

where:

• 35 mm - inside diameter
• 56 mm - outside diameter
• 9 mm - basic seal width
• 14.8 mm - overall / additional axial dimension associated with the seal construction

The 35 mm inside diameter corresponds to the nominal shaft sealing diameter.

The 56 mm outside diameter corresponds to the nominal housing bore.

The complete 9/14.8 mm axial specification should be retained when identifying the product.

Why is the 9/14.8 mm dimension important?

CORTECO 19016578 is not simply a conventional oil seal with one 9 mm width dimension.

The full catalogue dimension is:

35x56x9/14.8 mm

The additional 14.8 mm value reflects the extended geometry of the seal construction.

This is important when comparing the product with other seals such as:

• 35x56x8
• 35x56x9
• 35x56x9/12.5
• 35x56x9/14.5
• 35x56x9/15
• 35x56x10

Similar basic dimensions do not establish technical equivalence.

ACM - Polyacrylate Rubber

CORTECO 19016578 is manufactured from:

ACM - Polyacrylate Rubber

ACM is an elastomer widely used in automotive sealing technology, including appropriately designed sealing systems exposed to lubricating oils and elevated operating temperatures.

Material selection is a fundamental part of radial shaft seal specification.

A seal specified as:

ACM 35x56x9/14.8

should therefore not automatically be replaced by an identically sized seal manufactured from:

• NBR
• FKM/FPM
• VMQ

These elastomer families have different operating characteristics.

ACM vs NBR

ACM and NBR are different elastomer materials.

NBR is widely used for conventional oil and grease sealing applications, while ACM is commonly selected for particular automotive applications requiring the characteristics of polyacrylate rubber.

Therefore:

NBR 35x56x9/14.8

is not automatically equivalent to:

ACM 35x56x9/14.8

even if the nominal dimensions are identical.

ACM vs FKM/FPM

FKM/FPM belongs to the fluoroelastomer family and has different thermal and chemical characteristics from ACM.

A dimensional match therefore does not establish material equivalence.

When replacing CORTECO 19016578, the required elastomer should be checked against the original specification and actual operating conditions.

What does TC9 mean?

TC9 is the construction/profile designation used for CORTECO 19016578.

For this product, the seal incorporates an additional dust lip and a geometry represented by the complete 35x56x9/14.8 mm dimensional specification.

The full identification:

ACM TC9 35x56x9/14.8

is therefore considerably more useful for technical selection than searching only for:

35x56 oil seal

or:

35x56x9 oil seal

Seals sharing the same shaft and housing diameters can differ significantly in their lip arrangement, axial geometry and elastomer material.

Additional dust lip

CORTECO 19016578 incorporates an additional dust lip.

Its function is to help protect the primary sealing area against contamination approaching from the external side.

Depending on the operating environment, the additional lip can help reduce exposure to:

• dust
• dirt
• fine particles
• external contaminants

This is an important construction feature in drivetrain, axle and differential sealing applications.

CORTECO 19016578 drivetrain and differential applications

CORTECO 19016578 is catalogued for specific applications within the:

drivetrain / axle / differential sealing system

In these applications, the radial shaft seal operates on a rotating component and helps retain lubricant within the protected mechanical assembly.

The exact installation position depends on the design of the particular vehicle.

Before installation, verify:

• OE reference
• vehicle model
• drivetrain configuration
• installation position
• original seal construction

• MD707184 CORTECO
• CORTECO 19016578 MITSUBISHI

Why can MD707184 appear under more than one vehicle brand?

Cross-reference catalogues may associate the same reference with more than one vehicle manufacturer, particularly where components, transmissions or drivetrain systems share technical origins.

For CORTECO 19016578, MD707184 appears in cross-reference data associated with HYUNDAI and MITSUBISHI.

The exact application should always be confirmed for the specific vehicle before installation.

Why are 35x56x9 dimensions alone not enough?

Many radial shaft seals can share a 35 mm inside diameter and 56 mm outside diameter.

They may differ in:

• total width
• extended axial geometry
• elastomer material
• seal profile
• lip construction
• dust lip
• directional features
• intended operating medium
• application

Therefore, a generic:

35x56x9 oil seal

should not automatically be considered a replacement for:

CORTECO 19016578 ACM TC9 35x56x9/14.8

How to select a replacement for CORTECO 19016578

Before selecting an equivalent seal, verify:

• CORTECO reference 19016578
• 35 mm inside diameter
• 56 mm outside diameter
• full 9/14.8 mm axial specification
• ACM material
• TC9 construction
• additional dust lip
• installation position
• corresponding OE reference
• operating medium
• operating temperature
• shaft speed
• shaft sealing surface condition

Matching the basic dimensions does not guarantee technical interchangeability.

Installation of CORTECO 19016578

Before installation, carefully inspect and clean the shaft and seal housing.

Check for:

• wear grooves
• scratches
• corrosion
• burrs
• sharp edges
• contamination
• mechanical damage

The seal should be installed squarely and evenly using an appropriate installation tool.

Avoid tilting, twisting or deforming the seal during assembly.

Protect the sealing lip during installation

The sealing lip should not be pulled unprotected across:

• sharp edges
• threads
• splines
• grooves
• burrs

Where necessary, use an appropriate installation sleeve.

Damage to the sealing lip during installation can result in leakage even when the correct seal has been selected.

Check the shaft sealing surface

Before installing a new seal, inspect the surface on which the sealing lip operates.

Check particularly for:

• wear grooves caused by the previous seal
• corrosion
• scratches
• surface irregularities
• excessive wear
• mechanical damage

If the mating surface is significantly damaged, replacing the radial shaft seal alone may not eliminate the source of leakage.
