You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and theyrnmay not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because mostrnapplications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have anyrndoubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation
