1. Classification by Structure
   Stem-mounted casters are fixed by directly inserting a metal rod into the chair leg, commonly found in cross-border export products, such as 3-inch transparent universal double wheels; flower-core PU double-sheet casters use double-layer polyurethane (PU) material, providing significant noise reduction, such as the 2.5-inch Amazon cross-border model; hollow casters reduce weight through hollow design while maintaining load-bearing capacity; snap-ring casters enable quick disassembly and assembly through a snap-ring structure, such as the snap-ring version of 2-inch swivel chair universal wheels.

2. Classification by Material
   Metal materials include zinc alloy, aluminum alloy, etc., such as zinc alloy universal wheels and aluminum alloy 2-inch wheels, which offer high strength and wear resistance; plastic materials like TPR (thermoplastic rubber) silent wheels reduce friction noise through soft materials, commonly found in threaded rod TPR silent casters; PU wheel rim material combines the elasticity and wear resistance of polyurethane, such as 3-inch office desk chair wheels with a load capacity of up to 45 kilograms.

3. Classification by Function
   Fixed casters, once inserted into the chair leg, make the chair immovable, suitable for scenarios requiring stable positioning; casters with brake pads achieve fixation by stepping on the brake pad, such as some 2-inch universal wheels; seat-brake wheels automatically lock the wheels when the user sits down and unlock when standing up, enhancing safety; movable caster low-leg/high-leg styles are designed according to the height of the chair leg to meet different usage needs.

4. Classification by Design Features
   Concealed 360-degree rotating universal wheels are hidden under the chair leg through a low-profile design, maintaining overall aesthetics; premium 2-inch threaded rod European and American casters are designed for the European and American markets, meeting ergonomic standards; the threaded and inserted wire versions of 2-inch swivel chair universal wheels are fixed by threading or inserting wire, respectively, to fit different chair leg structures.
