Do you have something that would replace this hardware. The only markings I can identify are first on the wheel hub "OTI5"

I'm afraid we cannot replace this complete roller housing. We do not have anything that matches. Could you get away with just replacing the wheel by itself? If so, consider our 81-228 or 81-236, along with the 81-310 axle repair kit.
