CORTECO 19026774 ACM HTC9 35x55x9/15.5 mm Oil Seal - Toyota

1. Technical Specification

The complete designation CORTECO 19026774 ACM HTC9 35x55x9/15.5 mm should be retained during technical identification and procurement.

2. Radial Shaft Seal Construction

CORTECO 19026774 belongs to the radial shaft sealing category.

Radial shaft oil seals are designed to restrict lubricant leakage along rotating shafts while helping protect mechanical assemblies from external contamination.

The stated HTC9 configuration includes a primary sealing lip and an additional dust lip.

Its functional components include:

• A primary elastomeric sealing lip contacting the rotating shaft.

• An additional dust lip helping restrict the entry of external contaminants.

• ACM sealing material providing the required elastomeric contact.

• A seal body designed for installation in an appropriately dimensioned housing bore.

The precise internal reinforcement arrangement and garter spring configuration should be verified against the manufacturer's technical drawing.

3. HTC9 Profile - Technical Identification

HTC9 is a seal profile designation used in CORTECO product identification.

For CORTECO 19026774, the stated configuration includes an additional dust lip and two height dimensions: 9 mm and 15.5 mm.

The profile designation is important because shaft seals with identical nominal inside and outside diameters may have different lip arrangements, overall heights and mounting requirements.

HTC9 must not automatically be treated as interchangeable with TC, SC, HTC9Y or RHTC9Y profiles.

Dimensional similarity alone does not establish constructional equivalence.

4. ACM Polyacrylate Rubber - Material Properties

ACM (Acrylic Rubber) is a synthetic polyacrylate elastomer used in technical sealing applications, particularly where resistance to lubricating oils at elevated temperatures is required.

ACM compounds are commonly used in automotive transmission and drivetrain sealing systems.

Typical ACM characteristics

• Good resistance to many lubricating oils.

• Suitable heat resistance for selected elevated-temperature applications.

• Good resistance to thermal ageing in appropriately formulated compounds.

• Mechanical properties suitable for selected rotating shaft seals.

• Limited compatibility with certain water-based and aggressive chemical media.

• Low-temperature flexibility dependent on the compound formulation.

For many conventional ACM compounds, an approximate operating temperature range of -20°C to +150°C is commonly referenced.

This is general material information and not a confirmed temperature rating for CORTECO 19026774.

The permissible temperature range must be established from manufacturer documentation and actual operating conditions.

5. Dimensions 35x55x9/15.5 mm Explained

The dimensional designation identifies four important geometric parameters.

The 15.5 mm overall height is particularly important when evaluating installation space.

A shaft seal with dimensions 35x55x9 mm but a different overall profile may not be a suitable replacement.

Correct identification requires consideration of the complete dimensions and HTC9 design.

6. Toyota Differential and Drivetrain Applications

CORTECO 19026774 is associated with selected Toyota differential and drivetrain shaft sealing applications.

In these arrangements, a radial shaft seal helps retain lubricant inside the mechanical assembly while allowing the shaft to rotate.

The additional dust lip helps restrict the entry of dirt and other contaminants into the primary sealing area.

The exact mounting position depends on the differential or drivetrain construction.

Compatibility with a specific Toyota vehicle, model year, engine or transmission must not be assumed from dimensions alone.

The appropriate OE reference and vehicle configuration should be verified before installation.

7. Toyota OE Reference Numbers

The following Toyota numbers have been supplied as cross-reference identifiers for CORTECO 19026774.

These numbers are provided as identification references and require confirmation against the relevant manufacturer or vehicle parts catalogue.

They do not establish universal interchangeability between all listed Toyota components.

Vehicle-specific compatibility should be confirmed using the relevant OE number, vehicle identification data and assembly specifications.

8. CORTECO 19026774 Compared with Other 35x55 mm Oil Seals

Different radial shaft seals may share nominal dimensions of 35 mm inside diameter and 55 mm outside diameter.

However, they may differ in:

• Elastomer material.

• Primary sealing lip geometry.

• Additional dust lip configuration.

• Basic and overall height.

• Internal reinforcement.

• Shaft rotation requirements.

• Intended operating medium.

• Installation orientation.

For CORTECO 19026774, the principal identification characteristics are the manufacturer part number, ACM material, HTC9 profile and complete dimensions of 35x55x9/15.5 mm.

Any proposed alternative must be evaluated for dimensional and functional compatibility.

9. Oil Seal Selection and Engineering Considerations

Correct selection of CORTECO 19026774 requires verification of the shaft diameter, housing bore, installation depth and operating environment.

Important engineering considerations include:

Shaft Diameter and Surface Condition

The nominal shaft diameter is 35 mm.

The shaft contact surface must meet the requirements for radial shaft sealing, including appropriate surface finish, dimensional accuracy and running characteristics.

Housing Bore

The nominal housing bore diameter is 55 mm.

The bore must provide suitable retention and correct positioning of the seal.

Installation Height

The complete 35x55x9/15.5 mm geometry must be considered.

The additional profile height may affect installation clearance and positioning.

Operating Medium

The sealing material is ACM.

Compatibility with the actual lubricant must be confirmed, particularly where specialized transmission fluids or additives are involved.

Shaft Speed and Temperature

Permissible rotational speed and operating temperature depend on the seal construction, lubrication, shaft condition and elastomer formulation.

No exact operating limits should be assigned without manufacturer documentation.

Rotation Direction

The shaft rotation direction specification has not been confirmed for this product.

A directional sealing feature must not be assumed without verification of the exact CORTECO profile.

10. Installation and Maintenance

Before installing CORTECO 19026774, inspect the shaft and housing surfaces for damage, contamination and dimensional irregularities.

The shaft contact area should be free from defects that could damage the sealing lip or accelerate wear.

Recommended installation considerations include:

• Cleaning the shaft and housing bore.

• Protecting the sealing lip from sharp edges.

• Using suitable installation tools.

• Maintaining the correct installation orientation.

• Avoiding tilting during insertion.

• Following the manufacturer's recommendations for lip preparation and lubrication.

• Confirming sufficient clearance for the 15.5 mm overall profile height.

Incorrect installation may result in premature leakage, sealing lip damage or reduced service life.
