High-Capacity Flat-Free Casters with Rubber Wheels

These wheels cushion just as well as pneumatic casters over smooth or rough surfaces but are filled with polyurethane foam so they won't go flat. Their dual-wheel design provides better load distribution and easier turning than single-wheel casters.

The wheels have roller bearings for smooth rolling.
