Determining Capacity of an Old Trailer Axle with No Information on the Axle
Question:
I measured the spindle with a caliper. The trailer side where in think the grease packing sits measured 1.6020 inches. The interior bearing sits at 1.2520 inches. And the exterior bearing sits at 0.7475 inches. Also I learned that it's a drop axle. Thank you again for looking into weight limits and cross over part numbers for me.

The 15123 bearing is still common but I could not find any information on the 09057 bearing. But given that your hubs have the 4 bolt pattern it is likely that the axle is rated under 3,000 pounds. Most likely it is a 2,000 pound axle.
Measure the spindle where the 09057 bearing rides using calipers such as # PTW80157 I can see if there is a different bearing with the same inner diameter that is commonly used with 15123 and go from there.
Since you still have the trailer frame as well you can search it on the outboard and inboard sides for a plate that may have the capacity information listed. Or if you know the manufacturer and model of the trailer it came from I could potentially figure it out that way too.
