Why use Japanese Kits?
At Couplemate, we’ve found NSK Japanese bearings to be reliable for Caravans at high speed under all conditions.

We also recommend the use of High-Temperature axle grease, even in used in boat trailer bearings.

We stock only Japanese bearing kits, as these work well even when your caravan is running at high speeds.

All you have to do is give us a call, and we will deliver your bearing kits anywhere in Australia.

When considering caravan bearings, it is wise to select Japanese bearings rather than no-name, Chinese or Indian bearings.

For years Couplemate used Chinese bearings, and we regret it. The cost of warranty work was immense; however, the customer dissatisfaction level was higher and persuaded us to dump all bearings except for Japanese bearings.

In the last 15 years, we have had zero complaints from Japanese bearings. Problems from collapsed bearings have been found to originate from lack of servicing, magnet wear or brake shoe wear.

The Importance Of Seals In Your Bearing Kit
One of the essential things about bearing kits is the often-forgotten seal.

What are the oldest bearings?
The earliest bearings were made of wood, and animal fat was used to lubricate them. The ancient Egyptians used tree trunks as roller bearings to move large, heavy stones, which were used in the construction of pyramids. The earliest recovered example of a rolling element bearing is from 40 BC.

At Couplemate, we’re not all for the 100% rubber seal; we’d instead suggest a rubber seal with a metal outer. These have a spring around the inner rubber lip, to put a little tension on the axle journal—a great way to close the gap of 0.01mm.

We also do not suggest seals with a rubber outer casing, as they are difficult to install and are generally low-quality seals.
