These are premium versions of the 360-degree spinner wheels. They utilize advanced rubberized materials (like TPE or high-density TPU) and sometimes specialized magnetic or low-friction bearings designed specifically to dampen noise. They offer maximum maneuverability while prioritizing a near-silent roll, appealing to luxury and business travelers.

These are large, high-quality, fixed wheels typically found on traditional two-wheel upright luggage. They resemble rollerblade wheels, often made of durable polyurethane with sealed ball bearings. They are known for superior smoothness and durability on rougher terrain but only roll well when the bag is tilted and pulled (not pushed upright).

This refers to the function rather than the shape. Spinner wheels are full caster systems (like those in files dzcsd.jpg and dawda.jpg) that allow the luggage to be pushed or pulled in any direction without tilting, offering effortless movement through airports and smooth surfaces. They are characterized by a wide base and four or eight pivot points (four double wheels).

This set shows various configurations of black plastic wheels against a dark (black) background. It includes dual-wheel assemblies as well as a single, separate wheel component, highlighting the individual parts used in the full caster system.

This appears to be a single wheel mounted on a small, fixed housing. This type of wheel is typically used on the back or bottom of older-style upright luggage (two-wheel luggage) rather than modern 360° spinner luggage.
