Office Chair Making Noise
The causes and solutions for an office chair making noise are as follows:

An office chair making noise can be caused by various factors, and targeted solutions should be implemented based on the specific type and characteristics of the abnormal sound. For a regular office chair, a common cause is prolonged use of the lifting column, which leads to a sense of resistance around it and generates abnormal noise. In this case, lubricating oil can be evenly applied around the lifting column to reduce friction through lubrication, thereby eliminating the abnormal noise.
For a rolling stool, the root causes of abnormal noise and solutions are more complex. Common causes and handling methods are as follows: 1. Foreign object entanglement and dust accumulation Hair, pet fur, fiber threads, etc. on the ground can easily get entangled around the wheel axle. Dust and sand particles getting stuck in the bearing gaps can cause rolling stuttering and generate friction noise. The solution is to perform deep cleaning: use a flat-head screwdriver to disassemble the wheels and remove tightly entangled foreign objects. For surface entanglement, use small tweezers or a hook to pick it out, or use a static electricity adsorption method for cleaning. After cleaning, ensure there are no residual foreign objects around the wheel axle.
2. Lack of lubrication in the bearings After long-term use, the original lubricating oil in the wheel bearings (especially ball bearings) may dry up or be contaminated by dust, causing dry friction between metal parts and emitting a "squeaking" sound. In this case, lubrication maintenance is required: use a clean cloth to dip a small amount of sewing machine oil, light mechanical lubricating oil, or special office chair maintenance oil and apply it to the gaps between the wheel axle and the bearings. Rotate the wheels to evenly distribute the oil, and finally wipe off the excess oil stains. Before lubrication, clean the dust around the wheel axle to prevent impurities from mixing into the lubricating oil.
3. Aging or inferior wheel material Cheap hard plastic wheels or aging and hardened rubber wheels not only roll poorly but also generate relatively loud noise when rubbing against hard floors (such as tiles and wooden floors). Loose wheel structures can also cause abnormal noise. The solution is to replace the wheels: choose wheels with good material (such as soft rubber or silent plastic) and a sturdy structure to ensure reduced friction and vibration when in contact with the floor.
4. Mismatched or loose installation If the installation interface size of the wheels (commonly 11mm, 12mm, and 15mm) does not match the chair leg base or is not installed properly, rolling will cause shaking and impact sounds. In this case, perform a tightening check: turn the chair upside down and check if the connection between the five-star foot and the rolling wheels is loose. Also, check if the screws on other parts of the chair (such as the backrest and armrests) are tightened. If the wheel size does not match, replace them with wheels of the appropriate specification.
