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 3" Polyurethane Wheels

Diameter: 6 inTread: 2-1/2, 3 inCapacity: up to 9,000 lb

This collection gathers industrial casters used on warehouse carts on epoxy and smooth concrete. Expect wheel diameters 6 in, polyurethane treads, and capacities 1,600 to 9,000 lb. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
