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.

8" x 2-1/2" Ductile Steel Wheels

Diameter: 8 inTread: 2-1/2 to 3 inCapacity: 4,000 to 6,000 lb per wheelBrand: Durastar

The two ductile iron replacement wheels here come from Durastar, 8 in across on 2-1/2 to 3 in treads, rated 4,000 to 6,000 lb per wheel. You will find an 8 x 2-1/2 in ductile V-Groove industrial wheel rated 4,000 lb and an 8 x 3 in ductile V-Groove industrial replacement wheel rated 6,000 lb here. Ductile iron takes shock better than cast iron and still handles heat. Temperature ratings sit at -20°F to 800°F for most of the page.
