The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Stainless casters here serve warehouse carts, racks, and everyday plant fixtures. Catalog chips cover wheel diameters 3 in, stainless treads, and plate-mount frames. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. These medium-duty options cover everyday warehouse carts, racks, and everyday plant fixtures without jumping to extreme forged series.
