Repair an old trailer

I have an old boat trailer where the bearings are integrated in the wheel (there is no hub) and the wheel is held on by a castle nut. One of the wheels is gone, and I don't know where to find a replacement. I'll post a pic shortly.

Anyone have any experience with this type of setup that might know where I can find the parts I need?

I think their 8" fixed hub integral wheel is what i was looking for - thank you very much!

You're welcome. I wasn't quite sure of your setup but looking through their hubs I thought that was what you described. I've used them a few times and they have pretty much everything and prices are great.
