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.

5" dia. Polyurethane Casters for warehouse carts on epoxy and smooth concrete. Expect wheel diameters 5 in, polyurethane treads, and industrial frames. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. These medium-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
