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.

Diameter: 4, 5, 6, 8 inTread: 2 inCapacity: up to 1,200 lb

Duralast Polyurethane Wheels for bake carts, metalworking fixtures, and debris-heavy floors. Expect wheel diameters 4, 5, 6, 8 in, polyurethane and phenolic treads, and plate-mount frames. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. These medium-duty options cover everyday bake carts, metalworking fixtures, and debris-heavy floors without jumping to extreme forged series.
