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.

Diameter: 1-3/16 inCapacity: up to 850 lb

Stainless Steel Ball Transfer Units for heavy warehouse carts, die carts, and plant fixtures. Expect wheel diameters 1-3/16 in, steel and stainless treads, and industrial frames.
