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.

This 850 series aisle groups plate-mount casters built for warehouse carts on epoxy and smooth concrete. You will see wheel diameters 6 to 15-3/8 in, polyurethane and steel treads, and capacities 12,000 to 30,000 lb across the SKUs listed below. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Larger plates spread bolt stress on thick frames under continuous tow abuse.
