Bearing Seals Caravan and Boat Trailers

Bearing seals for caravan and boat trailers are what keep your bearing lube intact, ensuring the proper function of your wheels.

Seals for trailers and caravans are one of the most important—yet often forgotten—components of the axle system. This is because you’re in serious trouble if your seal fails.

How do I get the Right Bearing Seal?

This is a tough question but you will be surprised by the simple answer.

Let’s look at Dexter 2t drums. There are many seals that fit the same bearing combination.

Generally, we can identify the correct part by the inner bearing number. However, to be entirely sure, measure the ID of the axle where the seal fits and the OD of the drum where the seal is housed.

Some Dexter seals can vary by only a few millimetres so accuracy is essential.

Bearing Seals (Caravan And Boat Trailers) At Couplemate

We only sell seals that have a spring on the inside lip of the seal. (excluding Holden LM Seals) Look for this spring before you install your hub or drum. Sometimes, you’ll pop it right out—if you knock it into position with a little too much muscle.

Some Key Info On Your Bearing Seals

The spring provides a little tension on the rubber lip of the seal against the axle journal. Neither low-quality seals nor marine seals have springs to provide this tension.

As a result, marine seals are a tight fit on the axle and fit loosely into the steel housing in the disc or drum. Consequently, these seals push firmly against their axle shoulders.

We make most of our quality bearing seals from metal casting and include a spring on the inside of the seal. This spring puts pressure on the lip of the seal to ensure a tighter fit into the axle seal journal.
