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" x 1-1/4" Stainless Steel Casters

Diameter: 4 inTread: 1-1/4 inCapacity: up to 300 lb

This collection gathers plate-mount casters used on finished floors and quiet institutional carts. Expect wheel diameters 4 in, rubber, steel, and stainless treads, and capacities 220 to 300 lb. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. These light-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
