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.

Casters on the 5-1/4 x 7-1/4 plate pattern suit finished floors and quiet institutional carts. Typical builds show wheel diameters 12 in, rubber and steel treads, and capacities 1,300 lb. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. These medium-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
