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.

272 series dual-wheel casters spread load across two treads on a 4-1/2 x 6-1/4 plate for carts that need capacity without a taller single wheel. Phenolic, rubber, and cast-iron dual wheels in 3-1/4 to 6-1/4 inch diameters carry about 500 to 1,200 lb. Combined tread width near 4-1/2 inches improves flotation on soft floors. Bolt holes typically slot 2-7/16 x 4-15/16 toward 3-3/8 x 5-1/4. Match overall height when mixing with single-wheel corners.
