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. I attached a link down below that shows all of the bearings we offer as well.

In order to pick out the correct bearing buddy you will need know the pilot hole of your hub. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver to pry off the cap.

Clean the grease off and measure the opening with a caliper like the digital caliper # PTW80157.
