Ball casters are round balls that allows them to move in any direction and are mounted via a plate or stem, depending on the style you select. We offer stem ball casters that can support up to 300 lbs and plate casters that can support up to 3000 lbs.
Guidelines for Selecting the Right Caster Load Capacity:
In order to determine the load capacity for each caster, you must divide the combined weight and maximum load of the equipment by the number of casters to be used.
(Equip Weight + Max Load Weight) / # of Casters = Approx. Load Capacity
Example: unit weight is 100 lbs and max load is 500 lbs. The number of casters that will be used is 4.
So the formula is: (100 + 500)/4 = 150 lbs load capacity.
