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.

Rubber casters here serve finished floors and quiet institutional carts. You will see wheel diameters 8, 10, 12 in, rubber treads, and industrial frames across the SKUs listed below. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. These medium-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
