Office Chair Ball Bearing Accessories

Currently, no standardized product information explicitly labeled as 'office chair-specific ball bearing accessories' has been retrieved. However, some ball bearing turntable hardware accessories may be suitable for office chair scenarios, with prices ranging from 2.35 yuan to 3.6 yuan.

1. Related Accessory Types and Price References

According to available information, ball bearing accessories on the market mostly exist in the form of 'ball bearing turntables' or 'plastic turntables,' commonly used in advertising display cabinets, showcase trays, and other scenarios. For example:

• 4-inch/7-inch/9-inch Ball Bearing Turntables: Priced at approximately ¥2.35, these products typically use plastic materials and achieve low-friction rotation through ball bearing structures, potentially suitable for the base of office chairs or the rotating modules of swivel chairs.
• Yingguda Brand Ball Bearing Turntables: Priced at approximately ¥3.6, these also use plastic materials and emphasize load-bearing capacity and stability in design. If the size matches, they can serve as alternative solutions for office chair ball bearing accessories.

It should be noted that the above products are not explicitly labeled as 'office chair-specific,' and their suitability needs to be comprehensively evaluated based on specific dimensions, load-bearing requirements, and installation methods.

2. Core Functions and Selection Criteria for Office Chair Ball Bearing Accessories

Ball bearing accessories for office chairs (such as casters and turntable bearings) primarily serve support, rotation, and mobility functions. When selecting, the following parameters should be considered:

• Material: High-quality accessories often use steel ball bearings or high-strength plastics to ensure wear resistance and load-bearing capacity (typically requiring support for over 50kg).
• Size: They need to match the mounting holes on the chair legs or base, with common specifications ranging from 4 to 10 inches in diameter.
• Friction Coefficient: Low-friction design enhances rotational smoothness and reduces noise.

If existing ball bearing turntable products do not clearly indicate load-bearing parameters, it is advisable to prioritize branded products (such as Yingguda) and contact the seller to confirm their suitability for office chair scenarios.

3. Purchase Recommendations and Alternative Solutions

• Direct Purchase: If the accessory size is compatible with the office chair, you can try purchasing the aforementioned ball bearing turntables, but stability testing is required.
• Custom or Dedicated Accessories: Contact office chair manufacturers or professional hardware suppliers to obtain original ball bearing accessories (such as caster bearings and turntable modules). These products usually undergo rigorous testing and offer better compatibility.
• Repair Kits: Some brands offer office chair repair kits that include ball bearings, brackets, and other components. These may be more expensive than generic accessories but are easier to install.

Summary: The current market lacks explicitly labeled 'office chair ball bearing accessories,' but general-purpose ball bearing turntables can serve as temporary alternatives. It is recommended to prioritize obtaining dedicated accessories through manufacturer channels to ensure safety and durability.
