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.

8" x 2" Phenolic Casters

Match a 4 x 4-1/2 top plate when bolting casters under bake carts, metalworking fixtures, and debris-heavy floors. Catalog chips cover wheel diameters 8 in, phenolic treads, and capacities 1,250 lb. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. These medium-duty options cover everyday bake carts, metalworking fixtures, and debris-heavy floors without jumping to extreme forged series.
