Zhongtai Office Chair Casters
There is no clear information indicating the existence of a product specifically named 'Zhongtai Office Chair Casters'. Here is a detailed explanation:

Among the existing search results, the only caster product related to 'Zhongtai' found is the 'Xin Zhongtai Heavy-Duty Cast Iron Load-Bearing Universal Wheels'. These wheels come in sizes of 6 inches and 8 inches, are made entirely of iron, and possess high-temperature resistance, making them suitable for scenarios such as ovens. This product emphasizes 'heavy-duty load-bearing' and 'high-temperature resistance', belonging to a common type of casters in industrial or commercial settings. However, there is no mention of its compatibility or design association with office chairs.
Office chair casters typically need to meet the following core requirements:
- Lightweight and Quiet Operation: Office chair casters should reduce noise during frequent movement and avoid scratching the floor. Therefore, they often use soft materials such as polyurethane or nylon. In contrast, the 'Xin Zhongtai Heavy-Duty Casters' are made of cast iron, which is heavier and harder, potentially not meeting the quiet operation needs of office settings.
- Appropriate Load-Bearing Range: The load-bearing design of office chair casters is usually tailored to human weight (approximately 100-150 kg). In contrast, the load-bearing capacity of 'heavy-duty casters' may far exceed this range, leading to structural redundancy or excessive costs.
- Rotational Flexibility: Office chair casters need to have 360-degree free rotation capabilities, whereas industrial casters may focus more on directional movement or braking stability, with differences in structural design between the two.
When selecting casters for office chairs, it is recommended to prioritize the following parameters:
- Material: Polyurethane or nylon materials are more suitable for wooden or tiled floors;
- Size: Common diameters are 50mm (2 inches) or 65mm (2.5 inches), which need to match the installation holes on the chair legs;
- Load-Bearing: It is recommended that the load-bearing capacity of a single wheel be no less than 50 kg to cope with dynamic usage scenarios;
- Braking Function: Choose whether to equip with a braking device based on needs to enhance usage safety.
Currently, the 'Zhongtai' brand has not explicitly launched office chair-specific caster products. For further verification, you can contact the brand's official customer service or consult the product manual to confirm the applicable scenarios of specific models.
