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 collection gathers industrial casters used on light institutional and furniture-grade frames. Typical builds show wheel diameters 5 in, polyolefin treads, and capacities 145 to 600 lb. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. These light-duty options cover everyday light institutional and furniture-grade frames without jumping to extreme forged series.
