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 chemical, food-contact, and washdown carts. Expect wheel diameters 4, 5, 8 in, nylon, steel, and stainless treads, and capacities 300 to 1,250 lb. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. These medium-duty options cover everyday chemical, food-contact, and washdown carts without jumping to extreme forged series.
