Office Chair Small Feet
The 'small feet' of an office chair usually refer to the caster wheels. Taking the m10 caster wheel as an example, its core parameters and characteristics are as follows:

I. Basic Specifications
- Diameter: The diameter of caster wheels is typically 50-55mm. This size is designed to fit the wheel frame structure of most office chairs, ensuring both mobility flexibility and overall stability.
- Axle Diameter: It adopts the m10 thread specification (axle diameter of 10mm), which is an industry-wide standard. This facilitates compatibility when users replace or upgrade the wheels.
II. Load-Bearing Capacity The load-bearing range of a single wheel is approximately 50-80kg. For a five-wheeled office chair, the total load-bearing capacity can reach 250-400kg, meeting the daily usage needs of ordinary adults. If the user is relatively heavy or needs to carry heavy objects, it is advisable to choose a model with a higher load-bearing limit and regularly check the wear and tear of the wheels.
III. Materials and Suitable Scenarios
- PU Wheels (Polyurethane Wheels): They have a soft and quiet surface, suitable for scenarios where noise reduction is required, such as homes or offices. They also cause less damage to wooden floors, tiles, and other ground surfaces.
- Nylon Wheels: They have high hardness and strong wear resistance, suitable for high-frequency use in public places (such as conference rooms and libraries), but may produce slight noise.
- Soft Rubber Wheels: They have excellent elasticity and strong grip, specifically designed for uneven ground surfaces (such as carpets and stoneๆผๆฅ [Note: 'ๆผๆฅ' means 'joint' or 'seam' here, but in English, we can just say 'uneven ground surfaces' without translating it literally] areas), preventing the wheels from getting stuck or slipping.
IV. Maintenance and Replacement
- Regularly clean hair, dust, and other debris from the gaps between the wheels to prevent rolling obstruction.
- If the wheels show cracks, deformation, or rolling irregularities, they need to be replaced promptly. When replacing, ensure that the axle diameter of the new wheels (such as m10) matches the original wheel frame to avoid installation failure.
- For office chairs that are left stationary for a long time, it is recommended to lift the wheels or use a chair mat to prevent ground indentation.
V. Purchase Recommendations Choose the corresponding material based on the usage scenario: PU wheels for homes/offices, nylon wheels for public areas, and soft rubber wheels for complex ground surfaces. If multiple scenarios need to be accommodated, different materials of wheels can be prepared and replaced as needed.
