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.

Polyolefin casters here serve light institutional and furniture-grade frames. You will see wheel diameters 4, 5 in, polyolefin treads, and plate-mount frames across the SKUs listed below. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. These light-duty options cover everyday light institutional and furniture-grade frames without jumping to extreme forged series.
