CORTECO 19035225 ACM TC9Y 35x50x8.5/12 mm Oil Seal - Simmerring

1. Technical Specification

The dimensions 35x50x8.5/12 mm, ACM material and Honda OE reference are used in commercial catalogue identification.

Some listings use a rounded axial dimension of 9/12 mm. For technical identification, the more precise designation 8.5/12 mm should be retained.

2. TC9Y Radial Shaft Seal Construction

CORTECO 19035225 belongs to a specialized category of radial shaft seals designed to restrict lubricant leakage from rotating mechanical assemblies.

The TC9Y construction incorporates an additional dust exclusion lip and is associated with a spring-assisted primary sealing arrangement.

Main Functional Components

Primary sealing lip

The primary lip contacts the rotating shaft surface and restricts lubricant leakage from the sealed assembly.

Additional dust exclusion lip

The secondary lip helps prevent dust, small particles and external contamination from reaching the primary sealing interface.

Garter spring

A spring-assisted sealing arrangement helps maintain contact pressure between the primary lip and the shaft surface.

The exact spring configuration should be confirmed using the manufacturer's technical drawing.

ACM elastomer

Polyacrylate rubber provides elasticity and resistance to many lubricating oils used in mechanical assemblies.

Dual axial dimensions

The specified dimensions of 8.5 mm and 12 mm represent two axial construction measurements.

The precise location of the features responsible for the greater overall dimension requires confirmation from the manufacturer drawing.

3. What Does TC9Y Mean?

TC9Y is a construction profile designation used to identify this CORTECO radial shaft seal.

For this reference, the profile is associated with an additional dust exclusion lip and a spring-assisted primary sealing arrangement.

The complete TC9Y designation should be retained when selecting a replacement.

It should not automatically be considered interchangeable with:

• TC

• TC9

• HTC9

• RHTC9

• LHTC9

Differences may involve sealing lip geometry, protective elements, axial construction and installation requirements.

The TC9Y designation alone does not establish a particular hydrodynamic twist direction.

4. ACM Material - Technical Properties

ACM (Acrylic Rubber), also known as polyacrylate rubber, is a synthetic elastomer widely used in technical sealing applications involving lubricating oils.

It generally provides good resistance to many mineral oils and elevated operating temperatures.

Typical ACM Properties

• Good resistance to many mineral oils.

• Good resistance to thermal ageing.

• Good resistance to ozone.

• Suitable for selected dynamic shaft sealing applications.

• Limited resistance to fuels and certain organic solvents.

• Low-temperature performance dependent on compound formulation.

The actual performance of a particular ACM oil seal depends on its elastomer formulation and operating conditions.

5. Chemical Resistance of ACM

This table describes general ACM material characteristics and does not represent confirmed chemical resistance testing for CORTECO 19035225.

6. Temperature Resistance

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

Specialized formulations may have different temperature limits.

This range is general material guidance and is not a confirmed operating specification for CORTECO 19035225.

During product selection, the lubricant temperature, shaft rotational speed, lubrication conditions and frictional heating at the sealing lip must be considered.

7. Dimensions 35x50x8.5/12 mm Explained

The designation 35x50x8.5/12 mm identifies a seal with two specified axial construction measurements.

It should not automatically be treated as equivalent to a standard 35x50x8 mm or 35x50x12 mm oil seal.

The greater axial dimension may affect installation clearance and the position of the sealing elements relative to the shaft.

The exact dimensional geometry should be verified using the manufacturer's technical drawing.

8. Application - Honda Differential and Drive Axle

CORTECO 19035225B is catalogued for selected Honda differential and drive axle sealing applications.

In these assemblies, the seal restricts lubricant leakage where a rotating shaft passes through a stationary housing.

Commercial catalogue listings have associated the reference with selected Honda CR-V II (RD) variants, including certain 2.0 petrol and 2.2 CTDi versions.

However, a catalogue association does not establish compatibility with every vehicle configuration.

Correct selection requires verification of the original equipment reference, vehicle identification number and installation position.

9. Honda OE Reference 91203PWT003

Honda 91203-PWT-003 is associated with this CORTECO replacement reference in commercial catalogues.

The original part may also be described in Honda-related listings as a Mount Assembly Oil Seal.

The exact installation position must be confirmed against the relevant vehicle and assembly documentation.

10. Reference Numbers and Product Identification

For accurate product identification, the complete CORTECO reference should be used together with the Honda OE number where applicable.

11. Comparison with Other 35x50 mm Oil Seals

Radial shaft seals with similar nominal diameters may have different axial dimensions, elastomer materials and construction profiles.

These seals should not automatically be considered interchangeable.

CORTECO 19035225 differs in its TC9Y construction, ACM material and dual axial dimensions.

A standard TC 35x50x8 mm oil seal should not be used as a replacement without confirming technical compatibility.

12. CORTECO 19035225 Selection Criteria

Correct product selection requires verification of the complete manufacturer reference and installation requirements.

The following parameters should be checked:

Manufacturer reference

CORTECO 19035225 or 19035225B.

Sealing material

ACM polyacrylate rubber.

Construction profile

TC9Y.

Shaft diameter

35 mm nominal.

Housing bore

50 mm nominal.

Axial dimensions

8.5 mm and 12 mm.

Operating medium

The lubricant and its additives must be compatible with ACM.

Operating conditions

Temperature, shaft speed and pressure must remain within the permissible limits of the exact seal.

Mating surfaces

The shaft and housing must meet the installation requirements.

Honda OE compatibility

The original equipment reference must correspond to the specific vehicle and assembly.

Installation position

The seal must match the intended differential or drive axle arrangement.

The overall axial construction requires particular attention because an incorrectly selected seal may interfere with adjacent components or position the sealing lip incorrectly.

13. Installation and Maintenance Recommendations

Before installation, thoroughly clean the shaft and housing bore.

The shaft contact surface should be free from burrs, deep scratches, corrosion and excessive wear.

Recommended installation practices include:

• Verifying the Honda OE reference and TC9Y profile.

• Checking housing dimensions and available installation clearance.

• Protecting the sealing lips from sharp edges.

• Using suitable installation tools.

• Maintaining correct alignment during insertion.

• Preparing the sealing surfaces according to the vehicle manufacturer's instructions.

• Checking for lubricant leakage after commissioning.

Incorrect installation may damage the sealing lip, cause oil leakage or accelerate shaft wear.
