Office Chair Accessories Bearings
There are various types of office chair accessory bearings, and selection should be based on specific needs, with significant differences in price, brand, and material.
I. Common Types and Suitable Scenarios
Office chair bearings can be classified by structure into non-standard wrapped bearings, rotary stamped bearings, etc. Non-standard wrapped bearings are commonly used in executive chairs or furniture bar stools. The outer wrapping material reduces friction noise, making them suitable for scenarios with high requirements for quiet operation. Rotary stamped bearings enhance structural strength through stamping processes and are commonly found in the rotating mechanisms of swivel chairs, supporting frequent rotation and offering strong durability. Additionally, high-end ergonomic office chairs (such as the Galileo series) use iglidur® plastic sliding bearings, including two materials: iglidur® G general-purpose and iglidur® J high-wear-resistant. The former is suitable for seat automatic weight adjustment structures, while the latter is used for backrest rotation and depth adjustment parts. Their core advantages include lubrication-free operation, maintenance-free performance, and lower costs, while eliminating metal bearing noise through self-lubricating properties.
II. Brands and Customization Options
Mainstream brands in the market include Spejia, Congxin Bearings, Feite, and Fanbang Machinery, with product categories covering precision bearings, crossed roller bearings, flange bearings, etc. Precision bearings are suitable for scenarios requiring high rotational accuracy, such as the 360° unrestricted rotation of high-end swivel chairs. Crossed roller bearings enhance load-bearing capacity through crossed roller arrangements and are commonly found in large-sized office chairs. Flange bearings, due to their ease of installation, are mostly used in the connection parts between chair legs and gas cylinders. Some brands support customization according to needs, such as adjusting the inner diameter, outer diameter, or thickness of bearings based on chair dimensions, or optimizing materials for special use environments (such as humidity or high temperatures).
III. Price Range and Cost-Effectiveness
Office chair bearings have a wide price range. Ordinary models (such as non-standard wrapped bearings) cost approximately 0.71 to 5 yuan per unit, suitable for bulk purchases or economical products. Mid-to-high-end models (such as rotary stamped bearings and precision bearings) are priced between 10 and 22 yuan, mostly used in commercial or high-end home scenarios. iglidur® plastic sliding bearings, due to their material特殊性, are generally more expensive than traditional metal bearings but offer lower long-term usage costs (no lubrication maintenance required). When selecting, it is necessary to weigh initial investment against maintenance costs. For example, office chairs used in public places are recommended to prioritize maintenance-free models to reduce the frequency of later maintenance.
