150mm Heavy Duty Top Plate Fixed Castor (Fabricated Castor – Twin Wheel). The Top Plate measures 175x150mm with 105x80mm Fixing Hole Centres. The load capacity of this dual wheel castor is 1100kg.
The Wheel has a Polyurethane Tyre (92 Shore A) on a Cast Iron Centre Wheel with Ball Bearings. The polyurethane tyre is abrasion resistant with a low rolling resistance. The elasticity of the polyurethane allows the wheel absorb some of the rolling vibrations. This provides the user with a smoother and quieter operation yet is gentler on concrete floors compared to hard treads such as Cast Iron.
