Check product labels and instructions Product identification: The pressure bar itself or its packaging is usually marked with load restrictions. Carefully check whether there is a printed or labeled maximum load bearing value on the surface of the pressure bar, generally in kilograms (kg). For ex...Read more »

The service life of the pressure bar is affected by many factors such as material, frequency of use, and use environment. Generally speaking, the service life of the qualified pressure bar is about 5 to 10 years. The following is the specific analysis: Material and quality The use of high-quality...Read more »

Precautions for daily use Avoid excessive loading: Understand the load limit of the pressure bar, and do not allow the office chair to carry more than its specified weight of objects or people. Excessive weight will make the pressure rod bear too much pressure, accelerate the wear of internal par...Read more »

Structural foundation The pressure bar is mainly composed of cylinder, piston, piston rod, sealing ring and filled gas. The cylinder is a sealed chamber filled with a certain amount of inert gas (such as nitrogen), the piston separates the cylinder into two chambers, one end of the piston rod is ...Read more »

steel High quality carbon steel: This is one of the most commonly used materials for pressure rods. High quality carbon steel has good strength, toughness and corrosion resistance, and can withstand greater pressure without deformation or rupture. Through precise processing technology, it can be ...Read more »

Visual inspection Check the surface of the pressure rod: carefully observe whether the surface of the pressure rod is smooth, and there are no obvious scratches, dents, cracks or rust. Scratches and dents may weaken the structural strength of the pressure rod, cracks may directly lead to gas leak...Read more »

Pressure rod quality problem Material defects: If the pipe wall of the pressure bar uses inferior steel, the thickness is insufficient or the material is not uniform, the pressure resistance will not meet the standard requirements. In the normal pressure change or use process, it is easy to ruptu...Read more »

Normal pressure bar and high quality pressure bar Ordinary pressure bar: Ordinary pressure rods usually use relatively basic materials and relatively simple manufacturing processes. The wall of the tube may be thin, generally about 1-2 mm, and the quality of the steel used is relatively ordinary....Read more »
