Rigid Caster Wheel, Heavy Duty, 1000 lb, 8 in Dia Wheel, Mold-On Rubber Wheel, Roller Wheel Bearing, Corrosion Resist

These heavy-duty, double-ball race swivel casters are specially designed with extra-large raceways. Main load raceway features 1/2 in steel ball bearings that roll freely under maximum rated loads. Hardened 5/16 in steel ball bearings roll smoothly in hardened lower raceway. They are also designed to accommodate 2 in and 2 1/2 in tread width wheels. All components are cold-formed for demanding loads and rugged services. These casters boast an extra margin of strength that will result in long, dependable service on any heavy-duty application. The Series 34 rigid casters meet the same operating requirements. They're built tough with structurally formed legs with extra-heavy top plates to withstand heavy loads and continuous shocks.
