    Caster Load Capacity:

  • Equation for estimating load capacity: add furniture weight + furniture load divided by the number of casters needed equals the weight individual casters must support.
  • If load capacity is provided it is prudent to use heavier load capacity then needed.
  • Caster's overall strength is affected by size of complete caster, material caster is made of and wheel size including diameter and width.
  • Mobility has an affect on load capacities. Casters are made for occasional rolling. When stationary less stress is place on caster then when moving.
  • Generally speaking larger casters support more weight and roll easier.


  • Industry standards for antique style casters are often not provided. Our casters are quality reproductions designed to be used on furniture. They are very serviceable under normal conditions. As with all antique casters they are made for occasional rolling.
