In many cases, you'll want a swiveling, double-locking caster with a solid polyurethane wheel and a load rating in the 200-300 lb. range. A 2-3" wheel diameter will suit most applications. Larger wheels can be helpful if you need to roll out of a garage and onto the rough surface of a driveway.

How do I choose the right caster?

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.

What type of casters are best?

If the objects you are seeking casters for are not too heavy, then nylon casters are probably the safest choice. Nylon casters are typically smooth and non-abrasive and are usually installed 'ready polished' so they will not cause any issues with your hardwood flooring.
