Trailer Bearing Seal: The Unsung Hero of Your Rig

Why Trailer Bearing Seals Matter?

Your trailer's bearing seals play a crucial role in the safety and longevity of your rig. They protect the delicate wheel bearings from contamination, which can lead to premature wear and failure. In fact, bearing seals account for up to 80% of trailer bearing failures.

Trailer bearing seals prevent:

• Dirt and moisture from entering the bearing assembly
• Grease from leaking out
• Corrosion and rust from forming on the bearings

Types of Trailer Bearing Seals

There are two main types of trailer bearing seals:

• Lip seals: These are the most common type of seal, and they use a rubber lip to create a barrier between the bearing and the environment. Lip seals are relatively inexpensive and easy to replace.
• Labyrinth seals: These seals use a series of labyrinthine passages to create a barrier between the bearing and the environment. Labyrinth seals are more expensive than lip seals, but they are also more effective at preventing contamination.

How to Choose the Right Trailer Bearing Seal

When choosing a trailer bearing seal, it is important to consider the following factors:

• The type of trailer: Some trailers, such as boat trailers, require special seals that are designed to withstand water and salt.
• The size of the bearing: The seal must be the correct size for the bearing it is protecting.
• The operating conditions: The seal must be able to withstand the operating conditions, such as temperature and speed.

How to Install a Trailer Bearing Seal

Installing a trailer bearing seal is a relatively simple process, but it is important to do it correctly to ensure that the seal is effective. The following steps will help you install a trailer bearing seal:

1. Remove the old seal. Use a seal puller to remove the old seal from the bearing.
2. Clean the bearing. Use a clean rag to clean the bearing and the seal bore.
3. Apply sealant. Apply a thin layer of sealant to the bearing and the seal bore.
4. Install the new seal. Press the new seal into the seal bore until it is fully seated.
5. Lubricate the seal. Apply a thin layer of grease to the seal lip.
