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.

10" x 3" Cast Iron Casters

Plate sizes: 6-1/4 x 7-1/2Diameter: 6, 10 inTread: 3, 4 inCapacity: up to 8,400 lb

6-1/4 x 7-1/2 inch top-plate casters for warehouse carts on epoxy and smooth concrete. Typical builds show wheel diameters 6, 10 in, polyurethane and cast iron treads, and capacities 3,000 to 8,400 lb. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. Larger plates spread bolt stress on thick frames under continuous tow abuse. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
