This 22 Series (to 325 lb/ea) aisle groups plate-mount casters built for warehouse carts on epoxy and smooth concrete. Expect wheel diameters 3-1/2 to 8 in, polyurethane and stainless treads, and capacities 250 to 1,250 lb. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. Replace worn corners in matched sets when possible so the cart tracks straight under load. These medium-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
