Extra Heavy Duty Dual-Wheel Swivel Caster, 6" x 3" Duralast Polyurethane (95A) on Cast Iron Wheels

These forged steel dual wheel casters are built on the reliable Extra Heavy Duty (EHD) swivel caster platforms, which means flexibility if you need to match an existing bolthole pattern or overall height dimension. Dual wheel casters address the problem of how to minimize overall height and maximize load capacity on resilient tread wheels. Dual wheel casters also improve stability and swivel more easily than wider-face single wheels because differential action reduces the "scrubbing" effect of soft treads against the floors. All models have forged steel mounting plate and horn base with 1" integrally forged kingpins and precision tapered thrust bearings. Legs are 3/8" thick. Main Load Bearing - large diameter raceway CNC-machined for HPIa,, Swivel Technology. Secondary Load Bearing - precision tapered roller bearing capped with grease retainer.
