What Are Hub Assemblies?

When a trailer is using brakes, the hub is referred to as a 'Hub / Drum Assembly'; when the trailer is not having brakes installed, the hub is called an 'Idler Hub'

IDLER HUB

HUB DRUM

What is the difference?

The Hub / Drum shown above is the housing for a brake assembly. The brake shoes push out onto the inside of that hub. On an axle assembly without brakes, that housing is not needed.

Now that you know which assembly you need, click on the link above the image to be directed to the category of your choice.
