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.

Colson Ergonomic Polyurethane Total Lock Threaded Stem Casters

Diameter: 3-1/2, 4, 5 inTread: 1-1/4 inCapacity: up to 300 lbStem: threaded

Colson threaded-stem and plate-mount casters for carts and fixtures in carts that must lock wheel and swivel together. Typical builds show wheel diameters 3-1/2, 4, 5 in, polyurethane treads, and capacities 250 to 300 lb. Replace worn corners in matched sets when possible so the cart tracks straight under load. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These light-duty options cover everyday carts that must lock wheel and swivel together without jumping to extreme forged series.
