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. Typical builds show wheel diameters 4, 5, 6 in, steel treads, and capacities 700 to 1,200 lb. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. These medium-duty options cover everyday V-groove track and guided rail systems without jumping to extreme forged series.
