This 293mm solid rubber wheel on a plastic centre is ideally suited for sack trucks and trolleys that require a large diameter wheel for ease of movement. The 1 bore size can be reduced down using the pair of reducing bushes to either 1/2 (12.5mm ) or to 20mm. Using reducing bushes increases the hub length by 4mm and reduces the load capacity by 50%.
