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: 4 inTread: 1-1/4, 2 inCapacity: up to 300 lb

4" x 1-1/4" Rubber Wheels for finished floors and quiet institutional carts. Catalog chips cover wheel diameters 4 in, rubber treads, and industrial frames. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. These light-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
