6 x 3 Dual Wheel Green Poly on Cast iron Swivel Caster 6,000 lbs Capacity
Caster Barn's Medium Duty Dual wheel casters offers higher weight capacities with minimal overall heights, better load distribution, great floor protection and increased mobility than single wheel casters by spreading the weight over a wider floor surface while offering wheel differential action, resulting in less friction between the wheels and the floor, requiring less effort for the caster to swivel and maneuver. Caster Barn's Kingpinless Casters are designed for unsurpassed durability and used in abusive and demanding shock-load applications that may cause traditional kingpin casters to fail. The top plate and inner raceway is a unique one piece construction (stronger than machined and & welded designs); the inner and outer raceways are made from hot forged (ASTM 1045) steel, are precision machined and hardened and are held together by 1/2 hardened (HRC45) steel ball bearings. The legs are made from 3/8 steel and are uniformly double welded to the outer raceway, for optimum mobility, strength & stability. 3/4 grade 5 axle with lock nut.
