Detailed Specifications and Design

The National 15118 taper bearing cone is manufactured to meet strict dimensional tolerances, ensuring compatibility with wheel hubs and axle assemblies that require a cone bore of approximately 1.1895 inches. The cone length of 0.8125 inches and radius of 0.1400 inches provide the necessary geometry for proper load distribution and rotational stability. This part is essential for maintaining the integrity of the wheel bearing assembly, reducing friction and wear over time.

Compatible Vehicle Applications

This wheel bearing cone is compatible with a range of automotive makes and models that specify a taper bearing cone with these dimensions. It is commonly used in driveline and axle systems where precise bearing fitment is critical. For example, vehicles requiring a 30.2130 mm cone bore and 20.6380 mm cone length in their wheel bearing assemblies can benefit from the National 15118 part.

Common Issues Addressed by National 15118

• Wheel bearing noise due to worn or damaged cones
• Excessive play or looseness in the wheel hub assembly
• Uneven tire wear caused by bearing misalignment
• Vibration or roughness during wheel rotation
• Preventing premature bearing failure in axle assemblies

Installation Notes and Tips

When installing the National 15118 taper bearing cone, ensure the cone bore and length match the vehicle’s specifications exactly. Proper cleaning and lubrication of the bearing surfaces are critical to prevent premature wear. Use appropriate tools to avoid damage to the cone radius and maintain the integrity of the bearing assembly. Torque specifications should be followed according to the vehicle manufacturer’s guidelines.
