Wheel Hub Oil Seal Application

CORTECO 19016518B is catalogued as a front axle wheel hub oil seal.

In this application, the seal forms part of the protection system for a lubricated wheel hub assembly.

Its purpose is to help prevent lubricant loss and reduce contamination entering the sealed area.

Sealing performance depends on several factors:

• Condition of the mating surface.

• Correct installation.

• Proper interference fit.

• Wheel bearing condition.

• Lubricant compatibility.

• Vehicle operating conditions.

• Correct selection for the hub assembly.

A damaged or incorrectly fitted wheel hub seal may contribute to lubricant leakage and contamination of the bearing assembly.

CORTECO 19016518 - Nissan and Other Catalogue Applications

CORTECO 19016518B is associated in replacement-parts catalogues with selected vehicles, including:

These references indicate catalogue associations, not universal compatibility with every version of the listed vehicles.

Correct fitment must be confirmed using the vehicle variant, model year, drivetrain configuration and original equipment part number.

TB Seal Profile - Why Construction Matters

TB is the construction profile designation used for this CORTECO oil seal.

It should not automatically be considered identical to BA, BASL, B1SL or TC profiles.

Different sealing profiles may vary in:

• Sealing lip geometry.

• Outer-case construction.

• Spring arrangements.

• Dust protection features.

• Installation requirements.

• Housing fit.

When selecting a replacement, compare the complete technical designation rather than relying only on the dimensions 54x65x13 mm.

NBR Sealing Material

NBR, or Nitrile Butadiene Rubber, is widely used in automotive and industrial sealing applications.

Typical material characteristics include:

• Good resistance to many mineral oils.

• Compatibility with many mineral-based greases.

• Good mechanical properties.

• Suitability for appropriately designed dynamic sealing applications.

Actual performance depends on the specific NBR compound, temperature and sealing medium.

The exact hardness, permissible pressure, maximum shaft speed and operating temperature range should not be assumed without manufacturer specifications.

How to Select the Correct CORTECO 19016518 Oil Seal

Before ordering, verify:

1. CORTECO reference 19016518 or 19016518B.

2. Inside diameter - 54 mm.

3. Outside diameter - 65 mm.

4. Width - 13 mm.

5. TB construction profile.

6. NBR sealing material.

7. Original equipment part number.

8. Installation position.

9. Wheel hub and bearing assembly design.

10. Compatibility with the vehicle manufacturer's catalogue.

For automotive applications, matching dimensions alone is not sufficient to confirm correct fitment.

Wheel Hub Oil Seal Installation Guidelines

Before installing the CORTECO 54x65x13 mm oil seal, inspect the shaft, mating surface and housing bore.

Check for:

• Wear grooves.

• Corrosion.

• Scratches.

• Sharp edges.

• Contamination.

• Bearing play.

• Incorrect component alignment.

• Damage to the installation bore.

Use an appropriate installation tool to press the seal evenly into position.

Avoid deforming the seal or damaging its sealing surfaces.

Installation orientation and lubrication requirements must follow the vehicle manufacturer's service instructions.

Correct wheel bearing adjustment and the condition of mating components are also important for reliable sealing.
