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.

6" x 3" Polyurethane Casters

Diameter: 6 inTread: 3 inCapacity: up to 2,400 lb

Polyurethane casters here serve warehouse carts on epoxy and smooth concrete. You will see wheel diameters 6 in, polyurethane treads, and plate-mount frames across the SKUs listed below. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
