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.

8" x 3" Polyurethane Casters

Polyurethane casters here serve warehouse carts on epoxy and smooth concrete. Typical builds show wheel diameters 8 in, polyurethane treads, and industrial frames. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. 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.
