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.

5" x 1-9/16" Polyurethane Casters

Plate sizes: 2 x 3, 2-1/2 x 3-5/8Bolt holes: 1-3/4 x 2-13/16; 2 x 4Diameter: 5 inTread: 1, 1-1/4, 1-3/8, 1-9/16 inCapacity: up to 660 lb

Casters on the 2 x 3 plate pattern suit warehouse carts on epoxy and smooth concrete. You will see wheel diameters 5 in, polyurethane treads, and capacities 400 to 660 lb across the SKUs listed below. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set.
