Protect Your Bearings with Professional Seal Service

Hub seals are your trailer bearings’ first line of defense. If they fail, water, dirt, and road debris enter the hub and quickly damage bearings.

We provide:

✓ Inner and Outer Seal Replacement
✓ Premium Seal Installation
✓ Bearing Protection Service
✓ Grease Leak Repair

Replacing worn seals at the right time prevents larger and more expensive repairs later.

Signs Your Hub Seals Need Replacement

Seal failure often begins with small warning signs. Catching the issue early helps protect your trailer.

• Grease Leaking Around Wheels: Grease on the inside of your wheels or on the ground where your trailer sits usually indicates a failed inner seal allowing lubricant to escape.
• Contaminated Bearings: When seals fail, water and debris enter the hub. Contaminated grease causes rapid bearing wear and eventual failure.
• Grease Cap Will Not Stay On: Excess grease pressure caused by failed seals may push grease caps loose. This is a sign that internal sealing is compromised.
• Bearing Noise: Grinding or humming sounds from the wheels often result from contaminated bearings due to seal failure.
• Frequent Bearing Replacement: If you find yourself replacing bearings more often than expected, worn or improperly installed seals are often the root cause. Seals are inexpensive compared to bearings and hubs. Replacing them early protects the entire wheel assembly.

How Hub Seals Work

Hub seals perform two essential functions:

1. They keep grease inside the hub to properly lubricate bearings.
   
2. They keep contaminants such as water, dirt, and road salt out.

    

Most trailers use two seals per hub:

Inner Seals

Pressed into the hub on the spindle side. These seals create a tight barrier between the hub and spindle.

Outer Seals

Often referred to as grease caps, these protect the outer portion of the hub assembly.

Double Lip Seals

These seals offer enhanced protection by creating two sealing surfaces instead of one. They are commonly used in heavy duty applications.

When properly installed, seals maintain clean lubrication and protect expensive internal components.
