Super High Impact Polymer Caster WheelsCaster Barn's Super High Impact polymer Caster Wheels provide high load capacity without causing floor wear associated with metal wheels. Unlike polyurethane wheels, there is no risk of flat spots or delamination if these wheels are left parked for a prolonged period. Instead of injection molding, these wheels are compression molded and then machined. Their straight sided shape maximizes load capacity. The slight crown on their surface (tread) enables swivel casters to change direction more easily than flat tread wheels of the same size.
