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.

DuraStar 8" x 2-1/2" Polyurethane for chemical, food-contact, and washdown carts. Typical builds show wheel diameters 6, 8, 10 in, polyurethane and nylon treads, and plate-mount frames. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs. These medium-duty options cover everyday chemical, food-contact, and washdown carts without jumping to extreme forged series.
