Hydraulic piston rod is the key components of the pneumatic office chair.

In the office chair, the hydraulic piston rod is one of the key components of the pneumatic office chair. The pneumatic office chair controls the rise and fall of the chair through the up and down movement of the piston pneumatic rod in the cylinder. When the person sits on the chair, press the lifting switch, the gas spring rod is under pressure, and the chair is prompted to fall; When no downward pressure is generated, the chair will automatically rise ‌.

One of the common applications is in an office chair gas spring, where hydraulic piston rods are vital components. Hydraulic piston rods have to be made from good quality materials with appropriate properties to meet the requirements of their application. They have a variety of hydraulic piston rod materials, including unalloyed, alloyed, and stainless steel. The steel piston rod for the office chair gas spring should have high strength, wear resistance and corrosion resistance, so that the gas strut can work smoothly and has a longer service life.

Yield strength, tensile strength, and carbon content are key considerations in selecting materials for hydraulic piston rods. Example of gas spring rod material, Some of the applications use S235 JR steel for Hydraulic Piston rods, while others prefer steel with a slightly higher yield points, like S275 JR or S355J0. Employing stainless-steel grades such as 17-4PH, AISI 304, and AISI 410, steel piston rod have mechanical durability and corrosion resistance for more demanding applications.

Cold rolled steel is predominantly what both office chair gas springs use for the Hydraulic piston rod. While the specifications of these rods vary, typical sizes are 60mm, 80mm, and 100mm in diameter. Cold-rolled steel is commonly used for gas spring rods since it provides a good balance between strength and cost.

Corrosion and wear protection is another significant role played by surface treatment of hydraulic piston rods. To increase the rods' durability, they are often coated with chromium. Moreover, the selection of sealing materials is essential to guarantee the durability and effective operation of the gas springs. PTFE, Gas spring rod is involved in providing the chemical resistance and low friction coefficient includes as a common seal material, while elastomers (NBR, HNBR) are also a common seal material due to their flexibility and sealing properties.
