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.

3.5" x 1.25" Stainless Steel Casters

Casters on the 2-1/2 x 3-5/8 plate pattern suit light institutional and furniture-grade frames. Expect wheel diameters 3, 3.5 in, steel and stainless treads, and capacities 200 to 250 lb. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. These light-duty options cover everyday light institutional and furniture-grade frames without jumping to extreme forged series.
