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.

Casters w/ Polyurethane Wheels · 3"–5" · 300–350 lb

Diameter: 3, 4, 5 inTread: 1-1/4 inCapacity: up to 350 lb

This collection gathers industrial casters used on warehouse carts on epoxy and smooth concrete. Expect wheel diameters 3, 4, 5 in, polyurethane treads, and capacities 300 to 350 lb. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. These light-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
