How to Choose the Right Caster for Your Needs

Your Guide to buying the best Casters


Casters are an incredibly useful tool, perfect for items that need to be moved around quickly and easily. They can be used in a variety of contexts and are available in a range of sizes, types, and styles, making them a useful addition to both commercial and residential spaces. This buying guide will provide you with an overview of the different types of casters, their uses and benefits, and how to best choose the right caster for your needs.

Key features

  1. Load Capacity: The maximum weight capacity of the caster. Make sure it is sufficient for the particular application.
  2. Wheel Material: Made from metal, rubber, or plastic, each material offers different benefits and should be chosen based on the environment, weight capacity, and floor surface.
  3. Mount Type: Options include top-plate, threaded stem, and plate with holes. Choose a mount type that is compatible with the caster size and application.
  4. Wheel Diameter: The larger the wheel diameter, the easier it is to move heavier items. Smaller wheel diameters are more maneuverable.
  5. Wheel Type: Options include hard and soft rubber wheels as well as swivel caster wheels. Use hard rubber wheels for heavier loads and soft rubber wheels for lighter items.
  6. Bearing Type: Ball bearings offer a more durable option while roller bearings roll easier. Choose the bearing type that is most suitable for the application.

Important considerations


  • Ease of Mobility: Casters provide an easy way to move heavy objects since they can be attached to the bottom of furniture or industrial equipment, making them easily mobile.
  • Durability: Casters are generally made with a strong steel or aluminum frame, providing long-lasting use and supporting heavy loads.
  • Variety of Options: There are a variety of caster types and sizes available, making them suitable for a variety of needs.
  • Lower Price: Casters are generally less costly than purchasing and installing a permanent lift system.


  • Durability: Casters may not last as long as other kinds of wheels, making them less durable and potentially requiring more frequent replacements.
  • Noise: Depending on the materials, casters may cause more noise when used on a hard surface.
  • Mobility: While casters provide mobility, they may not have the same capacity as wheels with bearings, making them less suitable for heavier loads.
  • Cost: Casters may be more expensive than other wheel options.

Best alternatives

  1. Wheels - These are an alternative to casters that provide smooth, easy mobility over flat surfaces.
  2. Rollers - Rollers are cylindrical components that are used instead of casters when movement on a curved or irregular surface is required.
  3. Feet - Feet are also an alternative to casters and are typically used to provide additional stability.
  4. Slides - Slides are used in place of casters to provide a smoother motion across a variety of surfaces.
  5. Glides - Glides are an alternative to casters that provide a low-friction, low-impact method of moving furniture and other items.

An interesting fact about casters is that some of them have the ability to levitate. This phenomenon has been studied since the mid-19th century, when scientists conducted experiments using magnets and electric charges. Some believe that the ability to levitate is related to the power of one's imagination. Theories have been proposed to explain this phenomenon, but to date, no definitive answers have been found. This curious phenomenon has been documented in various books and articles, including one by the British physicist, Michael Faraday, who wrote about it in his 1832 book, Experimental Researches in Electricity.
