Office Chair Bantuo

In the field of office chairs, 'Bantuo' typically refers to the tray component, which is a key structure connecting the seat cushion and the gas lift, commonly found in the installation of computer chairs.

1. Core Functions of Bantuo

As a load-bearing and connecting component of an office chair, Bantuo primarily serves two purposes:

• Structural Support: Through metal or high-strength plastic materials, it evenly distributes the weight of the seat cushion to the gas lift, ensuring the stability of the chair. For example, the tray of the P600 computer chair is designed with a thickened steel plate, capable of withstanding over 150kg of pressure.
• Angle Adjustment: Some Bantuos incorporate a tilting mechanism, allowing users to adjust the angle between the seat cushion and the backrest according to their needs (typically ranging from 90° to 135°), enhancing comfort during prolonged sitting.

2. Installation and Maintenance Guidelines

• Installation Specifications:
  • Positioning Accuracy: It is essential to distinguish between the front and rear ends of the tray. The front end is usually close to the front edge of the seat cushion, while the rear end connects to the backrest support. Incorrect installation may result in the failure of the chair's tilting function or structural looseness.
  • Screw Fixation: When using short screws (such as 6×20 specifications), tighten them in a diagonal sequence in two stages to prevent tray deformation caused by unilateral stress. The P600 model requires four screws for fixation, with torque controlled between 3-5N·m.
• Daily Maintenance:
  • Regularly check the tightness of the screws and retighten them with an Allen wrench every six months to prevent loosening after prolonged use.
  • Avoid placing heavy objects or sharp items on the tray to prevent surface coating wear or structural deformation.

3. Common Issues and Solutions

• Squeaking Noise: If the chair emits a 'squeaking' sound when tilting, it may be due to a lack of lubrication or wear in the bearings inside the tray. Disassemble the tray and apply specialized lubricating grease (such as WD-40) to the bearings to resolve the issue.
• Tilting Malfunction: If the adjustment handle fails to lock the angle, check whether the locking mechanism inside the tray is jammed with foreign objects or if the spring has failed. The locking mechanism of the P600 model's tray is located at the rear end and requires gentle prying with a screwdriver to reset.

4. Purchase Recommendations

• Material Priority: Choose trays made of aluminum alloy or thickened steel plates, which have better deformation resistance than ordinary plastics.
• Compatibility: Ensure that the tray size matches the diameter of the gas lift (common specifications are 25mm or 28mm) to avoid installation difficulties.
• Functional Requirements: If multi-angle adjustment is needed, prioritize choosing a Bantuo with an independent tilting mechanism rather than a fixed design.

For further information on the parameters of specific Bantuo models, it is recommended to consult the product manual or contact the manufacturer for technical drawings.
