Casters:
These are wheels attached to a mounting plate (or stem) that allows for easy movement of furniture and equipment. Casters can swivel (providing flexibility) or have fixed wheels (providing straight movement).
Commonly used on office chairs, carts, storage units, and other furniture to facilitate movement.
Wheels:
These can be standalone wheels used for various applications like carts, trolleys, bikes, and more. They may come in different sizes and materials.
Can be designed for specific surfaces (e.g., rubber wheels for soft floors, hard wheels for concrete).
Both casters and wheels are essential features in facilitating mobility, providing convenience, and enhancing functionality in various home and industrial settings. If you need more specific information about a type of caster or wheel, feel free to ask!
