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.

6" 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. Expect wheel diameters 4, 6, 8 in, phenolic treads, and capacities 800 to 1,400 lb. Phenolic shrugs off heat and oils that soften rubber or poly on bake and shop carts. Replace worn corners in matched sets when possible so the cart tracks straight under load. These medium-duty options cover everyday bake carts, metalworking fixtures, and debris-heavy floors without jumping to extreme forged series.
