Nothing we stock carries more per wheel than these super heavy duty wheels, rated 360kg to 1,995kg across 100mm to 300mm, and the Colson X1 series sits at the top. Colson and Easyroll build for the heaviest rolling jobs.
The treads are polyurethane or rubber on cast iron or carbon steel centres, four wheels are all-metal cast iron, and the bearings are roller, ball or precision. A wheel that is cast iron right through can damage a good floor. Filter by load capacity, then confirm axle bore. Before you settle on a rating, work out how much of the total each wheel must carry using the buyer's guide.
