What you will need to do to pick out the correct replacement hub that will fit the spindles of your trailer is use a dial or digital caliper to get exact measurements of where the seal and bearings of your old hub rides. With that information I can determine what spindle you have and what hub would fit.

You also want to determine what bolt pattern wheels you have so that you pick out a hub that will fit your wheels.

Since you have an outer bearing of 15123 that portion of the spindle should be 1.25 inches. Based on that most likely the inner bearing portion of the spindle will have a 1.750 diameter and any of the hubs that are at the link on the right will fit it. But you need to measure to be sure.
