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.

12" x 5" Polyurethane Wheels

Diameter: 12 inTread: 5 inCapacity: up to 9,000 lb

This collection gathers industrial casters used on warehouse carts on epoxy and smooth concrete. Expect wheel diameters 12 in, polyurethane treads, and capacities 3,400 to 9,000 lb. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
