The railroad wheels below have been used in many applications: railbikes of many guys designs, they are so strong, they are being used in several Nuclear Power Plants to guide the containment covers.  So far - so good, let me know if that doesn't work.  I did not supply wheels to Chernobyl or 3 Mile Island.
