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 4-1/2 inch top-plate casters for bake carts, metalworking fixtures, and debris-heavy floors. Catalog chips cover wheel diameters 6 in, phenolic treads, and capacities 1,200 lb. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. Phenolic shrugs off heat and oils that soften rubber or poly on bake and shop carts. These medium-duty options cover everyday bake carts, metalworking fixtures, and debris-heavy floors without jumping to extreme forged series.
