4" x 2" Cast lron V-Groove Wheel Kingpinless Swivel Brake Caster - 600 Lbs Capacity

4" x 2" Cast lron V-Groove Wheel Kingpinless Swivel Brake Caster - Part # P51042VIRBTLB V groove wheels are designed to guide equipment by rolling on inverted angle iron track, however, they can also operate off the track thanks to the tread on either side of the v-groove. Cast Iron is the standard metal wheel used by most unless a heavier capacity or greater impact strength metal wheel is needed. For applications requiring more capacity or impact strength, check out the ductile steel & forged steel wheel caster options.  *Please note temperature ratings are dependent upon the bearing selected. Unless noted otherwise in the options, bearings will have a 180°F temperature rating. * Our kingpinless swivel caster rigs outlast traditional kingpin designs by preventing stretch-induced plate & fork separation. Providing more durability & more capacity (depending on the wheel) while reducing downtime and replacements."
