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.

Match a 2-1/2 x 3-5/8 top plate when bolting casters under light institutional and furniture-grade frames. Typical builds show wheel diameters 3 in, polyolefin, steel, and stainless treads, and capacities 200 lb. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. These light-duty options cover everyday light institutional and furniture-grade frames without jumping to extreme forged series.
