High-Strength Polyurethane Wheels
These wheels have an iron core for greater capacities than other polyurethane wheels. They combine the abrasion resistance of plastic with the shock-absorbing qualities of rubber. Use them on smooth or rough floors and in areas with debris.
Ball bearings are the easiest to roll. They are sealed for the best protection against dust and debris.
