Sorry, Kesta, but I didn't see your original post.  If you have 8 bolt wheels on that size trailer, it is most likely that you have 5200# or 6000# axles.  The bearings are the same for 5200#, 6000# and 7000# Dexter axles.  The inner bearing/race would be 25580/25520, and the outer bearing/race would be 14125A/14276.  There are two seal possibilities, one with a 2.25" ID and one with a 2.125" ID.  The brakes will be 12" x 2".  Some other brand axles can use Dexter hubs, etc.  It is likely that the axles on your Exiss are either Dexter or compatible.

I'm not sure that any of this answers your questions, so if I can help further, let me know.  Feel free to call me at 317-846-5839.
