Office Chair Gas Lift Scraping the Ground-Ehang Furniture

The main causes and solutions for the gas lift of an office chair scraping the ground are as follows:

Improper Adjustment or Aging: If the height of the gas lift is adjusted to its extreme positions (either too high or too low), the exposed metal rod may become too long after prolonged use, making it prone to friction against the ground. After more than 3 years of use, the aging of the seal ring can lead to a decrease in the stability of the gas lift, causing it to sink and scrape the ground under pressure.
Seal Wear or Air Leakage: Frequent lifting and lowering or long-term heavy loads can cause the internal rubber ring of the gas lift to wear out, leading to slow air leakage and a gradual decrease in support height, causing the bottom metal rod to touch the ground.
Installation Problems: If the gas lift is not properly aligned with the base or seat during installation, or if the base screws are not tightened, the lower end of the gas lift may come into contact with the ground.
Sinking Problems: After more than 3 years of use, nitrogen leakage inside the gas lift can cause its height to gradually decrease. When it reaches the lowest point, the outer wall of the metal rod may scrape the ground.

Base Deformation or Loosening: If the seat base is deformed due to impact or if the screws at the connections are loose, the entire gas lift may tilt and touch the ground. If the rotating base and chassis are loose, the chassis may sink, lowering the minimum height of the gas lift and causing friction.
Structural Deviations: Abnormal tilt angles of the five-claw base, excessive design tolerances at the connection between the base of a cheap swivel chair and the gas lift, or deformation of the explosion-proof base steel plate can lead to abnormal contact between the gas lift and the ground.

Uneven Ground: If the ground is not flat enough, the base of the gas lift may not be able to bear the load evenly, causing repeated scraping of local areas of the ground when the chair is moved.
Detached Anti-Slip Foot Pads: If the anti-slip foot pads are detached or damaged, the exposed metal claws or connections may directly rub against the ground, affecting the contact angle between the gas lift and the ground.

Immediately lower the seat height to the middle position and check if the base screws are loose and tighten them if necessary.
If adjustment is ineffective, install a nylon pad at the bottom of the gas lift for cushioning.

Wipe the outer wall of the gas lift with silicone oil every quarter to reduce friction.
In northern regions during dry winter indoor conditions, regularly lubricate the lifting shaft of the gas lift with a lubricant to prevent the seal ring from cracking.
