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 1-1/4" Polyurethane Casters

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

This collection gathers plate-mount casters used on warehouse carts on epoxy and smooth concrete. Catalog chips cover wheel diameters 3, 4, 5 in, polyurethane treads, and capacities 300 to 350 lb. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. These light-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
