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.

40 Series casters for warehouse carts on epoxy and smooth concrete. You will see wheel diameters 4, 5, 6, 8 in, polyurethane, polyolefin, and stainless treads, and plate-mount frames across the SKUs listed below. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. These medium-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
