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.

4 x 4-1/2 inch top-plate casters for V-groove track and guided rail systems. You will see wheel diameters 4, 5, 6 in, steel treads, and capacities 700 to 1,200 lb across the SKUs listed below. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set.
