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.

Plate sizes: 3-1/8 x 4-1/8Bolt holes: 2-3/8 x 3-3/8 slotted to 3-7/16Diameter: 3 inTread: 1-1/4 inCapacity: up to 275 lb

Match a 3-1/8 x 4-1/8 top plate when bolting casters under finished floors and quiet institutional carts. Typical builds show wheel diameters 3 in, rubber treads, and capacities 275 lb. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. These light-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
