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.

4-1/2 x 6-1/4 inch top-plate casters for heavy warehouse carts, die carts, and plant fixtures. Typical builds show wheel diameters 8 in, steel treads, and capacities 6,000 lb. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. Larger plates spread bolt stress on thick frames under continuous tow abuse. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade.
