Trailer makers unfortunately do not usually maintain records of the smaller components parts such as bearings that are used in the manufacture of their trailers but we do carry a broad assortment of replacement bearings, races and grease seals shown on the linked page.
The best way to select your new bearings is to pull one of your hubs and remove its inner and outer bearing and grease seal to obtain those items' part numbers. Then it is a simple matter of searching our site. You can refer to the linked photo to see the usual placement and appearance of bearing and seal part numbers.
You can also find the axle rating on the axle stickers and that can help narrow down the options.
If part numbers cannot be found you can measure the spindle where the bearings and seal ride and the hub bore with a precision caliper. Part numbers are the best and easiest way to find new bearings and seals. The linked articles will also help you with your bearing replacement.
