Woody, we press them in there. Generally, with aluminum, if you cut a hole .003 undersize a bearing should stay in. Mind you, in a situation like what is pictured, a flanged bearing is a better application. It was a lip that you can press against one side, so it prevents it from being pushed out in one direction. You should not need to epoxy bearing.

We don't have an accurate scale in our lab, so we can't give an exact answer to it, but my estimate is about 50 pounds. The wheels are custom made. They are 4" delrin with aluminum hubs and urethane treads.
