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" Polyurethane Wheels

Capacity: up to 15,500 lb

Polyurethane casters here serve warehouse carts on epoxy and smooth concrete. Expect polyurethane treads, industrial frames, and capacities 1,550 to 15,500 lb. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. These extreme-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
