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.

Polyurethane casters here serve warehouse carts on epoxy and smooth concrete. Catalog chips cover wheel diameters 6, 8, 10 in, polyurethane treads, and plate-mount frames. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
