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. Expect wheel diameters 6 in, polyurethane and nylon treads, and capacities 1,200 lb. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. 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.
