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 18 series aisle groups plate-mount casters built for finished floors and quiet institutional carts. Typical builds show wheel diameters 6 in, rubber treads, and capacities 450 to 600 lb. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet.
