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 4" Forged Steel Wheels

Diameter: 8 inTread: 3, 4 inCapacity: up to 23,000 lb

8" x 4" Forged Steel Wheels for forging carts, aerospace fixtures, and multi-ton movers. Catalog chips cover wheel diameters 8 in, steel treads, and industrial frames. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These extreme-duty options cover everyday forging carts, aerospace fixtures, and multi-ton movers without jumping to extreme forged series.
