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.

5" x 1-1/4" Rubber Casters for finished floors and quiet institutional carts. Typical builds show wheel diameters 3, 4, 5 in, rubber treads, and plate-mount frames. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. These light-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
