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 plate-mount casters used on light institutional and furniture-grade frames. Typical builds show wheel diameters 3-1/2 in and stainless treads. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. Replace worn corners in matched sets when possible so the cart tracks straight under load. These light-duty options cover everyday light institutional and furniture-grade frames without jumping to extreme forged series.
