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.

This collection gathers plate-mount casters used on heavy warehouse carts, die carts, and plant fixtures. Catalog chips cover wheel diameters 4 in, stainless treads, and capacities 750 to 3,200 lb. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. These heavy-duty options cover everyday heavy warehouse carts, die carts, and plant fixtures without jumping to extreme forged series.
