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.

This collection gathers plate-mount casters used on finished floors and quiet institutional carts. You will see wheel diameters 3, 4, 5 in, polyolefin and rubber treads, and capacities 275 to 300 lb across the SKUs listed below. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. These light-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
