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.

9" x 5" Polyurethane Wheels

Diameter: 9 inCapacity: up to 4,100 lb

9" x 5" Polyurethane Wheels for warehouse carts on epoxy and smooth concrete. Catalog chips cover wheel diameters 9 in, polyurethane treads, and industrial frames. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. These medium-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
