Office Chair Caster Models

Common models of office chair casters mainly include specifications such as 2-inch, 2.5-inch, and 3-inch. Specific types cover threaded rod insertion type, flat-bottom type, and snap-ring type. The materials are primarily PU and transparent plastic. Functionally, they are divided into swivel casters and fixed casters, with some models featuring brake functions. Here are the details:

Classification by Size:
2-inch casters are the most common specification for office chairs, suitable for most standard office chairs, such as 'Swivel caster 2-inch double-wheel threaded rod M10 insertion snap-ring boss chair swivel chair computer chair office chair caster' and '2-inch black PU fixed caster office chair accessory'. 2.5-inch and 3-inch casters are mostly used in scenarios requiring higher load-bearing capacity or a larger range of movement, such as '2.5-inch hollow swivel caster hollow threaded rod insertion silent caster' and 'Cross-border export insertion-type 3-inch transparent swivel double-wheel furniture office gaming chair smooth and durable caster'.

Classification by Installation Method:
The threaded rod insertion type is the mainstream design, fixed to the chair legs through metal threaded rods or insertion rods, such as 'Selected 2-inch threaded rod European and American caster GJWB with brake swivel caster' and '2.5-inch 3-inch snap-ring black transparent wheel insertion PU caster'. Flat-bottom casters are installed directly through the bottom surface, suitable for specific chair leg structures, such as '2-inch flat-bottom PU caster'.

Classification by Function:
Swivel casters support 360-degree rotation, facilitating flexible movement, such as 'Hengshitong transparent wheel 2-inch PU silent swivel caster' and 'Cross-border export office chair swivel caster 2-inch all-black furniture caster'. Fixed casters only allow forward and backward movement, suitable for scenarios requiring directional restriction, such as '2-inch black PU fixed caster office chair accessory'. Some models are also equipped with brake functions, allowing the chair to be fixed in position at any time, such as 'Selected 2-inch threaded rod European and American caster GJWB with brake swivel caster'.

Classification by Material:
PU casters are quiet and wear-resistant, suitable for hard floors, such as '2-inch black PU fixed caster office chair accessory' and 'Hengshitong transparent wheel 2-inch PU silent swivel caster'. Transparent plastic casters are lighter and often used in gaming chairs or scenarios where transparency is desired, such as '2-inch transparent double-wheel gaming chair caster' and 'Cross-border export insertion-type 3-inch transparent swivel double-wheel furniture office gaming chair smooth and durable caster'.
