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.

Polyurethane Casters - Duralast Rigid

Capacity: up to 2,700 lb

This collection gathers industrial casters used on warehouse carts on epoxy and smooth concrete. Expect polyurethane treads and capacities 1,150 to 2,700 lb. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
