Office Chair Noise

Office chair noise may be caused by issues with the wheels, connecting parts, frame, or other components, and can be resolved through targeted cleaning, lubrication, tightening, or replacement of parts.

Wheel-Related Issues and Solutions

• Foreign Object Entanglement and Dust Accumulation: Hair, fibers, or other debris on the floor can entangle the wheel axles, or dust can get stuck in the bearing gaps, causing rolling resistance and friction noise. Solution: Use a flat-head screwdriver to disassemble the casters, clean the foreign objects from the central axles, and then reassemble them; for surface entanglement, use tweezers to remove the debris or rub a plastic pen against a cloth to generate static electricity and attract the hair.
• Lack of Lubrication in Bearings: If the lubricating oil inside the wheel bearings dries up or becomes contaminated, the metal parts will rub against each other dryly, producing a "squeaking" sound. Solution: Use a clean cloth to dip into sewing machine oil or special maintenance oil, apply it to the wheel axles and bearing gaps, rotate the wheels to distribute the oil evenly, and then wipe off any excess oil.
• Aged or Inferior Wheel Material: Cheap hard plastic wheels or aged rubber wheels roll unevenly and can produce noise when rubbing against hard floors. Solution: Replace them with silent PU casters, which can effectively reduce friction noise.
• Mismatched or Loose Installation: If the wheel interface size does not match the chair foot base or is not installed properly, rolling can cause wobbling and impact noise. Solution: Turn the chair upside down, check, and tighten the connection between the five-star foot and the casters.

Connecting Part Issues and Solutions

• Loose Connecting Screws: Screws at the connections of the backrest, armrests, etc., may loosen due to long-term stress, causing parts to rub against each other and produce a creaking sound. Solution: Tighten all loose screws and apply lubricating oil to metal rotating shafts and joint gaps.
• Lack of Lubrication in Chassis Rotating Shafts: For chairs with a rocking and reclining function, dry lubricating oil in the internal metal springs and rotating shafts can cause friction noise. Solution: Apply lubricating oil to the rotating shaft positions to reduce metal friction.
• Wear at the Connection Between the Gas Lift and the Five-Star Foot: The contact positions between the top of the gas lift and the chassis, and the bottom and the five-star foot, can wear out due to long-term weight bearing, producing friction noise when the body moves. Solution: Check the wear condition and replace the gas lift or five-star foot if necessary.

Other Issues and Solutions

• Noise from the Gas Lift: If the gas lift is a product from a shady workshop that adds oxygen, it may have high friction due to air leakage and pose an explosion risk. Solution: Stop using it immediately, check its safety, and replace it with a qualified gas lift.
• Damaged Wheels on the Five-Star Foot: Issues such as detached wheel clips, cracked five-star claws, or crushed wheels can cause noise. Solution: Repair or replace the damaged wheels or five-star foot.
