How long is the service life of the pressure bar?

Factors affecting the service life of the barometric bar
Frequency and intensity of use:
If the office chair is frequently raised and lowered every day, such as in an office environment, many people share a chair, or the user needs to adjust the height of the chair frequently to adapt to different office scenarios, the internal mechanical structure and sealing components of the air pressure rod will accelerate wear due to frequent friction. Under such high intensity use, the service life of the pressure rod may be shortened.
In addition, if the user often carries out violent actions on the chair, such as frequent rotation, shaking or overweight use (exceeding the pressure bar’s specified bearing range), it will also cause damage to the pressure bar, leading to its early damage.

Environmental factors:
The temperature has a significant effect on the service life of the pressure bar. In the high temperature environment, the gas pressure inside the pressure rod will increase, increasing the pressure of the tube wall and seal; In the low temperature environment, the toughness of the material may be reduced, and it is easy to crack. For example, an office chair placed in a window in direct sunlight or a cold warehouse without heating for a long time can adversely affect the performance of its barometric pressure bar.
Humidity is also a key factor. If the office chair is in a humid environment, such as near a water source or in a basement with high humidity, the metal parts of the pressure bar are easy to rust, and the seals may be moldy and aging due to moisture, thereby reducing the service life of the pressure bar.
Quality factors:
High quality brand pressure bar, using high quality steel, advanced manufacturing process and good sealing materials, its service life is relatively long. For example, an air pressure bar that has passed strict quality certification (such as BIFMA certification) may have a service life of 5-8 years or even longer under normal conditions of use.
The quality of the poor pressure rod, the material may not pass, such as the wall steel strength is not enough, or the quality of the seal is poor, prone to gas leakage, pipe wall rupture and other problems, the service life may only be 1-2 years, or even shorter.
General service life range
Under normal conditions of use (that is, the frequency of use is moderate, the use of a good environment, and the quality is qualified), the service life of the pressure rod is about 3-5 years. However, this is only a rough range, the actual service life will vary due to the above various factors. Some high-end brands of pressure rods, in the ideal use of the environment, the service life can reach 8-10 years. In order to ensure safety, even if the pressure bar appears to be fine, it is recommended to check or replace it after a longer period of use (such as more than 5 years).
