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.

Diameter: 3 inCapacity: up to 1,200 lb

3-13 x 4-13 inch top-plate casters for bake carts, metalworking fixtures, and debris-heavy floors. Expect wheel diameters 3 in, phenolic and nylon treads, and capacities 300 to 1,200 lb. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These medium-duty options cover everyday bake carts, metalworking fixtures, and debris-heavy floors without jumping to extreme forged series.
