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 3" Cast Iron Wheels

Diameter: 9 inCapacity: up to 7,000 lb

This collection gathers industrial casters used on heavy warehouse carts, die carts, and plant fixtures. Expect wheel diameters 9 in, cast iron treads, and capacities 3,000 to 7,000 lb. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Replace worn corners in matched sets when possible so the cart tracks straight under load. These heavy-duty options cover everyday heavy warehouse carts, die carts, and plant fixtures without jumping to extreme forged series.
