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.

2-11/16 x 3-5/8 inch top-plate casters for light institutional and furniture-grade frames. You will see wheel diameters 2-11/16, 3.5, 4, 5 in, polyolefin, steel, and stainless treads, and capacities 230 to 300 lb across the SKUs listed below. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles.
