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.

4 x 4-1/2 inch top-plate casters for chemical, food-contact, and washdown carts. Typical builds show wheel diameters 5, 6, 8 in, nylon treads, and capacities 1,000 to 1,250 lb. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. These medium-duty options cover everyday chemical, food-contact, and washdown carts without jumping to extreme forged series.
