Coul you give me the axis diameter and the plug size it uses,
It this a polyurethane wheel?
Polyurethane wheels, generally speaking, are used on caster wheels. They do not have shock absorption like a foam-filled wheel somewhat has, and if you were to slice through the wheel, it would be the same material all the way through. We would not consider this a polyurethane wheel.
As we are not the manufacturer of this wheel assembly, we do not have the axis diameter or plug size; however, this is compatible with the Activecare Spitfire 1310 or 1410.
