Randy, I have only purchased top mounted pillow block roller bearings here for conveyor equipment drive systems. They specialize in motion machinery equipment. I would call and ask as they can supply many brands of bearings.
Hi Randy. We may have the bearings for your dirt bike wheel. Without knowing what you have it's impossible to say. If it's a standard size we would have it on the shelf. One problem we run into with dirt bikes and other automotive type applications is often the factory will take a standard bearing and have it modified in some way so they can capture the aftermarket sales. In that case we would not be able to help you. I would think a rear wheel bearing would be standard but I'm not certain of that. If you have dimensions (it's most likely metric) and you could take a picture of what you have, one of our sales people would be happy to look into it for you.
I wouldn't be surprised if they do carry (or can order) them. I've bought bearings there for a variety of applications.
