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.

Flangeless

Diameter: 1, 1-1/2 inCapacity: up to 250 lb

Flangeless for chemical, food-contact, and washdown carts. Expect wheel diameters 1, 1-1/2 in, nylon, steel, and stainless treads, and industrial frames. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These light-duty options cover everyday chemical, food-contact, and washdown carts without jumping to extreme forged series.
