The main difference between office chair casters and standard furniture casters, is that the office chairs normally have dual wheels on a single caster where the standard one has a single wheel. This allows easier movement over both carpeted and bare floors for the chairs. The single wheel ones tend to press in to a carpet and not roll as smoothly.
The standard caster and office chair one are both built with ball bearing at the axle, making them move easily over hard surfaces. The standard casters for heavier furniture, such as carts and larger pieces, mainly have a hard rubber wheel to handle any excess weight and long use. An office chair rarely moves any great distance with any real amount of weight on it.
Rubber Casters
The stationary caster differs with all others in that it is made with a flat bottom. This allows it to keep whatever piece of furniture it is attached to in one place while still allowing it to be moved quite easily to be cleaned behind and then slid back in place. These are very advantageous when the furniture is in a high dust or dirt area.
Cart casters differ greatly from office chair casters in that their wheels tend to be almost three times as big. These are designed specifically to handle heavy weight over a lot of moving around. Each cart is normally equipped with at least one or two casters with a locking mechanism to prevent unwanted movement.
The office chair caster tends to move much quieter than some cart wheels also. This allows for close proximity work and not to disturb others. If your chair moves around too much though, you may want to switch to a stationary style caster.
Choose your caster carefully, whether it is for your cart, cabinet or office chair. Make sure that it is rated for whatever weight you will be putting on it. A caster that is too light for the use being placed on it will break in a very short period of time.
