I really wish there was a way to determine what bearings a trailer needed without actually pulling the wheel off and checking, but there isn't. The only two solution I have for you would be to remove the hubs and get the numbers that are stamped on the bearing or for you to remove the hubs and use a digital or dial caliper to measure where the bearings and seal ride (see pic).

With that info I can help you figure out what you need.
