This page shows all of our Standard Swivel Hollow Kingpin Casters, sometimes referred to as Stemless Casters. Available in sizes from 3" up to 5" diameters with capacities up to 350 lbs per caster. These Casters are a lifesaver to many customers when they have a unique or uncommon stem size and need to adapt and attach casters. Stemless Casters are explicitly made to accommodate any stem, bolt, or mounting hardware 1/2" diameter and under where a standard caster can not connect. Some equipment may have permanent stems, but the customer may want to add casters; this is where hollow kingpin casters come in handy. Easily slide your stem directly through the center of our stemless caster, add a nut to the bottom of the stem to secure it, and you are now good to roll.
