This unique polyurethane on aluminum wheels offer both ergonomic and economic advantages over standard polyurethane wheels. Two independent swivel surfaces roll on a common axle. The result is reduced rolling resistance, initial start forces, and extended swivel caster life. In addition, the use of these wheels eliminates the need for costlier dual-wheel casters.
