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 2" Polyurethane Casters

Casters on the 4 x 4-1/2 plate pattern suit chemical, food-contact, and washdown carts. You will see wheel diameters 4 in, polyurethane, nylon, and stainless treads, and capacities 800 lb across the SKUs listed below. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. These medium-duty options cover everyday chemical, food-contact, and washdown carts without jumping to extreme forged series.
