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.

4" x 2" Casters

Diameter: 4 inTread: 2 inCapacity: up to 1,600 lb

4" x 2" Casters for warehouse carts, racks, and everyday plant fixtures. Catalog chips cover wheel diameters 4 in, industrial frames, and capacities 800 to 1,600 lb. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These medium-duty options cover everyday warehouse carts, racks, and everyday plant fixtures without jumping to extreme forged series.
