Your old drum is worn and braking feels uneven. You install this 12" hub and drum for 5,200 to 7,000 lb axles. Pre-greased bearings and a setup that matches your axle help the brakes apply evenly again.
Designed for 5,200 lb to 7,000 lb axle spindles, this hub and drum fits many equipment and cargo trailers. Matching your bearing sizes is the easiest way to confirm compatibility.
The hub and drum are built as one unit, so replacing both at once helps maintain proper alignment between braking and bearing surfaces.
Bearings are pre-packed and races are installed, which cuts down installation time and helps ensure everything is properly seated.
The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.
On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)
To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)
Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

Hi everybody. Andy here with etrailer.com. Let's take a real quick look at this Terran Industries trailer hub and drum assembly. Now this is designed to fit your 7,000 pound trailer axles and it's going to work with most standard trailer axle setups. This 12 inch brake drum is going to provide the surface for your brake shoes to grip during braking. And the eight on six and a half inch bolt pattern is a common fit for most heavy duty trailer wheels.
As you can see, the lug nuts are included with this and the bearings are also included and they are, this is going to be pre-greased. So this does come with the inner bearing that is already included. That's already installed there. Number 25580 and you can see probably a little bit there that it's already greased inside. And then you're going to get the outer bearing that you're going to have to install of 14125A.
And then the inner and outer bearing races are already pressed in again with grease inside. And then you probably already saw the grease seal on the back here that's already pressed in along with a grease cap. Everything to keep your bearings properly greased and protected from contaminants. And I mentioned the lug nuts are included for the half inch studs. Now if you happen to have any other further questions, don't hesitate to reach back out to us.
We do wanna be sure that you're getting exactly what you want and need. But I think that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.
