Specs:
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.

Hello etrailer friends and neighbors. I'm Steven with etrailer.com. Today we're looking at this Agricultural Trailer Hub Assembly for 11,500 pound axles. Now it is an 8 on 8" lug pattern, and again, it is for agricultural use only. Now that being said, this will fit farm trailers. It is designed for non-braked axles.
It's got a nice built-in grease circuit here on the top so you can lubricate everything. And again, it's got the eight lugs and studs included. I'll turn it around here for a back view real quick. Now again, I got that built-in grease fitting I told you about to easy lubrication. It also comes with the grease seal, the cap, the inner and outer bearings.
And like I mentioned, the lug studs and the lug nuts as well. The races are also already pressed in there from the factory, so you don't have to worry about installing those. Now this does work with a TRP spindle # SP-819275-145 and it has a max speed rating of 20 miles per hour. Again, this is ag use only, so you shouldn't be going faster than that anyways. It's rated 5,790 pounds.
Now the pilot hole diameter here, it's gonna fit a 6". The grease cap flange, the outer diameter on the grease cap flange itself is gonna be 3.16". And this does have a offset of -1.50, so -1.5". Now the inner bearing, that's gonna be your larger one here. The part number is 3780 with 2" diameter and the outer bearing, your smaller one is a part number 2790 or a 1.3125" inner diameter.
Again, the races are included, but the inner race is 3720, the outer race is 2720. Now it has an inner diameter of 2.50, so 2.5" on the inner diameter of the grease seal. The outer diameter of the grease seal is 3.756". Well folks, I know it's a lot of information. I hope this information's been helpful for you. Again, this is our look at the Ag Trailer Hub Assembly for 11,500 pound axles with 8 on 8" wheel stud pattern. I'm Steven, have a great day.
