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.

2-1/2 x 3-5/8 inch top-plate casters for light institutional and furniture-grade frames. Expect wheel diameters 3 in, stainless treads, and capacities 200 lb. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These light-duty options cover everyday light institutional and furniture-grade frames without jumping to extreme forged series.
