Office Chair Hydraulic Rod

If there are issues with the office chair hydraulic rod, corresponding repair measures can be taken or it can be directly replaced based on the specific fault manifestations.

Common Faults and Repair Methods

• Chair cannot be raised or lowered:
  • Poor internal sealing of the hydraulic rod: Invert the chair and carefully use tools to disassemble the connection between the hydraulic rod and the chair seat. Check if the sealing rubber ring is damaged. If it is, purchase a compatible sealing rubber ring for replacement and then reassemble it.
  • Control valve failure: Try cleaning the valve to remove any possible impurities. If the problem is still not resolved after cleaning, a new control valve needs to be replaced.
• Strange noises:
  • Lack of lubrication in the hydraulic rod: Use professional hydraulic oil or lubricating oil and drip an appropriate amount onto the moving parts of the hydraulic rod. Then repeatedly raise and lower the chair to evenly distribute the lubricating oil.
  • Loose components: Use a wrench or other tools to tighten the loose screws.

Replacing the Hydraulic Rod

If you do not want to repair it, you can also replace the hydraulic rod. Its price varies depending on factors such as specifications and brand. For example, the price of a 4-stage sinking hydraulic rod for a gaming chair starts at ￥131.00; the price of a Hengkang explosion-proof 4-stage gas rod for adjusting the height of an office chair is ¥34.0. When replacing, for a stool without screws, step on the bottom with both feet and shake it to remove the gas rod part. Tap around the circular part of the gas rod to knock it out. Buy a gas rod of a similar size online and install it. First, install it on the base, then put the stool on it, and sit on it to press it tightly.

Precautions

Repairing the hydraulic rod of an office chair is somewhat dangerous. Before operation, ensure that the chair is in a stable state to avoid injury caused by the chair falling during the repair process. If you have no repair experience or cannot solve the problem, it is recommended to seek the help of professional repair personnel. Do not operate blindly to avoid damaging the chair or causing harm to yourself.
