When you buy furniture to be placed on hardwood floors, you must also buy hardwood floor casters to prevent damage from moving heavy objects. The casters are attached to the bottom of the legs of the furniture. This link : https://www.castercity.com/furniture-casters-hardwood-floors/
What makes a good caster wheel?
There are many types of casters for different surfaces. Some are best for protecting hardwood floors, while others are designed for carpeted floors. Casters are important for furniture that weighs over 200 pounds.
If your casters are made of hard plastic or nylon, they will pierce and scratch your floors. They will also gouge them. It is better to use softer materials.
Urethane casters are an excellent choice for floors made of granite or marble. Their smoothness makes them great for lobbies, lobby areas, and classrooms. You can find these casters in the same color options as nylon casters.
Soft Rubber Wheels are another option for hardwood floors. These casters are available in two and three-inch diameters and come in a variety of colors. This coating should work on most low-pile rugs.
Albion 01 Series is one of the best-selling light-duty casters. With a single ball bearing raceway and a swivel section that has a 2 to 4 inch diameter, these casters offer a smooth gliding experience on hard surfaces.
Another option is the Shepherd Baron Series. These casters are heat treated to improve wear. They are suitable for medical equipment, fixtures, and office furniture. Besides being available in a variety of color options, these casters also have double ball bearing raceways.
