Bearing Wheel Office Chair

Among the products related to bearing wheel office chairs, the socket-type caster set is a relatively common choice. Its 2-inch size is suitable for most swivel chairs and features bearings, a plastic frame, and quiet operation. It is priced at ¥20.0, with monthly sales of 3 units, and is manufactured by Zhongshan Zhuoyue Casters Manufacturing Co., Ltd..

Core Product Features
This caster adopts a socket-type installation design, fitting chair foot sockets with a diameter of approximately 20mm. It is easy to install and offers high stability. The 2-inch wheel diameter (about 50mm) is a small to medium-sized wheel suitable for carpets or hard floors, ensuring mobility flexibility without causing instability due to an overly large wheel diameter. The bearing structure is a key component, typically using ball bearings or roller bearings, which significantly reduce rotational friction, making chair steering smoother and extending the wheel's lifespan. The plastic wheel frame is mostly made of high-strength engineering plastics (such as nylon or polypropylene), balancing lightweight and impact resistance, and can bear a dynamic load of about 50-80kg, meeting the needs of ordinary office scenarios. The quiet design is achieved by optimizing the wheel surface material (such as TPR or PU soft rubber), reducing noise from friction with the ground, making it especially suitable for open office environments or nighttime use.

Applicable Scenarios and Limitations
These casters are suitable for regular office chairs, conference chairs, or home computer chairs, especially in scenarios requiring frequent movement or steering. However, it should be noted that the plastic wheel frame may deform under long-term heavy loads (such as exceeding 100kg) or in high-temperature environments, and the soft rubber wheel surface wears faster on rough floors (such as concrete). For higher load-bearing capacity or wear resistance, consider metal wheel frames or hard wheel surface products.

Purchase Recommendations
When replacing office chair casters, first confirm whether the diameter of the original chair foot socket matches the 2-inch size and check if the bearing rotates smoothly (without jamming or abnormal noise). Additionally, the quiet effect is directly related to the wheel surface material. For tiled or wooden floors, it is recommended to choose TPR or PU wheel surfaces; for carpets, hard wheel surfaces can be selected to improve passability.
