Load Weight & Wheel Size

The first consideration for caster selection is to determine the combined weight of the equipment and maximum load on this equipment. Generally, the greater the weight, the larger the wheel required for the caster. Larger wheels distribute weight and roll more easily over floor obstructions.

       To determine the load capacity for each caster, divide the combined weight of the equipment and maximum load by the number of casters to be used. This is the load that each caster and wheel must support. Always select a caster and wheel that are rated for a capacity greater than the calculated load per caster. This allows for unusual conditions that could change the performance of the caster.
