Office Chair Silencing Methods
Office chair silencing can be achieved through the following methods, which should be tailored to the specific cause of the abnormal noise:
1. Dealing with Bearing Noise in Sihoo M18 Chairs The abnormal noise in this model of chair often stems from friction at the bearing connections. It is recommended to use WD40 Blue Can Lubricant (with a small straw). Lay the chair down and place paper pieces underneath to keep it level, then spray the lubricant at the bearing connections (about five places). The lubricant can penetrate into the bearings, reducing direct friction between metal components and thus eliminating the abnormal noise. Ensure that the lubricant is evenly applied during operation and avoid excessive spraying that may leave residues.
2. Targeted Solutions for Squeaking Noises in Office Chairs Squeaking noises are usually caused by two factors:
- Loose Screws: Thoroughly inspect all the connecting screws of the chair components and tighten them one by one using a screwdriver, paying special attention to the connections between the backrest and the seat cushion, and between the five-star base and the chair body.
- Five-Star Base and Caster Issues: If the noise is caused by friction between the nylon casters and the ground or loose connections, replace them with silent PU casters. These casters are made of a softer and more wear-resistant material, effectively reducing friction noise. Alternatively, add adhesive paper gaskets between the casters and the five-star base connections or inside the holes to fill the gaps and reduce component wobbling, thereby suppressing abnormal noises.
3. Eliminating Buzzing Noises When Dragging Chair Legs If the chair legs are made of carbon steel, dragging them on the ground may produce low-frequency buzzing noises. You can choose extra-small chair leg pads, whose inner diameters should match the diameter of the bottom ends of the chair legs. These pads form a buffer layer when put on, reducing direct friction and protecting the floor. If the pads are not the right size, you can use tennis balls as an alternative: press a tennis ball onto the bottom of each chair leg, using its elastic material to wrap around the metal legs. Experiments have shown that this method can significantly reduce noise without affecting the stability of the chair.
4. Other General Silencing Tips For temporary or low-cost needs, tennis balls can be used as "silent shoes": cut a small opening at the top of a tennis ball with a knife and directly put it on the chair leg. The elastic material absorbs vibration energy and reduces friction noise. This method is suitable for most metal or hard plastic chair legs, but the wear of the tennis balls should be regularly checked and they should be replaced in a timely manner to maintain the effect.
Precautions: Before operation, confirm the specific location of the abnormal noise on the chair to avoid blind treatment. After using the lubricant, let it sit for 10-15 minutes to allow full penetration before testing the effect. When replacing casters or leg pads, ensure that the new components are compatible with the original chair structure to avoid new noise problems caused by size mismatches.
