4" x 2" Ductile Steel V-Groove Wheel Swivel Caster - 1,250 Lbs Capacity

4" x 2" Ductile Steel V-Groove Wheel Swivel Caster - Part # 146DVRB420S Ductile V-Groove wheels are designed to guide equipment along inverted angle iron tracks but can also function without a track due to the tread on both sides of the V-groove. Made from a combination of alloys that provide excellent tensile strength, these wheels come with extra thick treads, hubs & walls. Ductile steel is a step up from cast iron, offering higher capacity & temperatures. For even greater capacity, consider the heavier-duty forged steel wheels. * Please note temperature ratings are dependent upon the bearing selected. Unless noted otherwise in the options, bearings will have a 180°F temperature rating.
