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 4" Polyurethane Casters

Diameter: 6 inTread: 4 inCapacity: up to 6,500 lb

This collection gathers industrial casters used on warehouse carts on epoxy and smooth concrete. You will see wheel diameters 6 in, polyurethane treads, and capacities 6,500 lb across the SKUs listed below. 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.
