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 2-1/2" Ductile Steel Wheels — 1" Roller Bearing Hamilton

Diameter: 6 inTread: 3 inCapacity: up to 7,000 lb

6" x 2-1/2" Ductile Steel for heavy warehouse carts, die carts, and plant fixtures. Expect wheel diameters 6 in, steel treads, and industrial frames. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. These heavy-duty options cover everyday heavy warehouse carts, die carts, and plant fixtures without jumping to extreme forged series.
