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.

Atx Off-road Wheels

Diameter: 4, 5, 6, 8 inTread: 2 inCapacity: up to 400 lb

This collection gathers industrial casters used on outdoor and rough-yard carts. Expect wheel diameters 4, 5, 6, 8 in, polyolefin, thermo rubber (TPR), and rubber treads, and capacities 200 to 400 lb. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. These light-duty options cover everyday outdoor and rough-yard carts without jumping to extreme forged series.
