Office Chair Rotation Sound

The sound produced when an office chair rotates is usually caused by worn mechanical parts, loose structures, or insufficient lubrication, and can be resolved through targeted repairs.

Worn Mechanical Parts

The bearings, gears, or connecting parts of an office chair may wear out after long-term use. When the chair rotates, these parts generate friction due to uneven surfaces or increased gaps, producing squeaking or noisy sounds. For example, aging seals inside the gas lift cylinder or worn bearing balls can cause direct metal contact and sound during rotation. Solution: If the wear is minor, disassemble the chair and apply specialized grease to the bearings, gears, and other parts. If the parts are severely damaged (e.g., broken bearings or chipped gears), contact the manufacturer to replace them with parts of the same specifications.

Loose Structure

Loose screws at the connections between various parts of the chair are a common cause of abnormal sounds. If the screws connecting the base to the lift rod, the chair wheels to the base, or the backrest to the chair body are not tightened properly, relative displacement between the parts can occur during rotation, resulting in friction and sound. Solution: Use a wrench to check the screws on the base, chair wheels, and backrest one by one, and tighten any loose parts to the specified torque. If the screws are stripped (the threads are worn and cannot be locked), replace them with screws of the same specifications, or use thread-locking adhesive to reinforce the threaded holes. Allow the adhesive to cure before reinstalling.

Insufficient Lubrication

If moving parts such as the gas lift cylinder and its sleeve, or the backrest pivot, lack lubrication, direct metal-to-metal friction can produce harsh sounds. For example, when the lubricating oil inside the gas lift cylinder dries out, increased resistance during lifting or rotation may be accompanied by a "squeaking" sound. Insufficient oil in the chair wheel bearings can cause stuttering and sound during rotation. Solution: Apply specialized grease (such as white lithium grease) to parts like the gas lift cylinder sleeve and backrest pivot to reduce metal friction. For chair wheel bearings, add a small amount of sewing machine oil (choose an oil that is not volatile and has moderate viscosity), and rotate the chair to distribute the lubricant evenly.

Other Considerations

If the above methods do not work, there may be damage to the chair's internal structure (such as a leaking gas lift cylinder or a deformed base), and you should contact a professional repair technician or the manufacturer's after-sales service. During daily use, avoid vigorous rocking or overloading the chair, and regularly check the tightness of the screws and replenish lubrication to extend the chair's lifespan and reduce abnormal sounds.
