The gas spring features an actuator that lowers or raises the chair when pressed by the paddle or lever. This holds materials necessary for adjusting the height of the cylinder, such as pressurized nitrogen gas and oil to lubricate the adjustments. The top part of the cylinder is the gas spring, and it usually has a diameter of 1.1 inches. Standard office chair gas cylinders have two parts. While activated, the chamber alone raises the height of the chair, applying pressure at the same time will decrease the height of the chair. The air chamber of the gas cylinder connects to a plunger or piston that, when activated, moves air in or out. This gas cylinder sits between the wheelbase and the seat and uses a lever, handle, or paddle to activate the mechanism. The hydraulic gas cylinder on an office chair is a pneumatic feature that allows you to adjust the height of the chair. For a stubborn cylinder shaft in the mechanism, you can try applying a little lubricant.What is an Office Chair Hydraulic Cylinder? To remove the shaft from the mechanism under the seat, use a pipe wrench with a "twist and pull" motion. To remove most gas cylinders you need a rubber mallet with a wood buffer to bang out the 5 star base from the bottom.
