These 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, reduced initial start forces, and extended swivel caster life. In addition, use of these wheels eliminates the need for costlier dual-wheel casters. The 6 x 3 and 8 x 3 sizes are triple-wheel design.
Two tread designs are offered (crown and flat face) along with three hardnesses (80A, 95A, & 75D). The wheels are non-marking and maintenance free.
