Keyhan Gas Cylinder
Prolonged sitting in a chair, particularly when the chair's height does not align with the table, can lead to discomfort and pain in the neck and spinal regions. To address this issue, adjustable chairs, which offer various features for user convenience, have become a favored option for long-term use in both workplace and home settings.
These adjustable chairs allow for height modification and 360-degree seat rotation, enabling users to customize their seating arrangement for optimal comfort. This capability is facilitated by a gas lift system. Whether one prefers a higher or lower seating position to engage with a desk or to relax, the lifting cylinder makes it simple to achieve the desired height.
Currently, gas lift mechanisms are integral to the manufacturing of various types of office chairs, swivel chairs, gaming chairs, and stools. This component is situated beneath the chair seat, linking the base to the chair's mechanism.
The significance and function of using a gas jack
Recognizing the significance and necessity of using gas cylinder in office chairs is crucial for establishing a comfortable and ergonomic work environment. The gas jack enables users to adjust their seating position, which is vital for enhancing physical health and preventing injuries associated with prolonged chair use.
When the seat height is properly adjusted, the feet remain flat on the floor, and the knees are bent at a 90-degree angle. This positioning reduces pressure on the back, neck, and shoulders, thereby preventing musculoskeletal complications.
Being able to adjust the chair to individual needs not only promotes health but also enhances comfort and productivity in the workplace, leading to an overall improved sense of well-being.
Components and operational mechanism
A comprehensive understanding of the functionality of office chair gas jacks necessitates knowledge of their components. Gas jacks are made up of a cylinder and a column, containing compressed gas, which is predominantly nitrogen. The internal gas pressure within the cylinder produces the force required for the chair's vertical movement, enabling it to move both upward and downward.
Gas jack's column is constructed from a steel tube with a diameter of 50 mm, which encases the cylinder assembly and is securely attached to the seat base.
The cylinder is a tube made of alloy steel with a diameter of 28 mm, containing the second cylinder, piston and control valve. The control valve is attached to a lever or handle that allows you to easily adjust the seat height by releasing or increasing gas pressure.
The activation of the seat lever facilitates the release of gas from the cylinder, allowing the piston to move freely and adjust the seat height accordingly. To raise the seat, gas pressure is released in a controlled manner through the piston’s action. When the user applies pressure, the resulting gas compression decreases the seat height, bringing it back to its original level.
Operation of jack hinges on strict adherence to the standard values, the purity of nitrogen gas, and the accurate prediction of the pressure applied by the user's weight, which must remain within the air pressure expansion range. If these conditions are not met, the jack's functionality may be compromised in a short time, leading to a reduction in seat height without any pressure application.
It is therefore essential to choose a standard gas cylinder to ensure proper fit and performance of your seat.
Sizing table
A variety of gas cylinders is available for different types and use of chairs.
Various jacks are utilized in the production of executive chairs, office chairs, gaming chairs, and stools to address the different needs of users.
The height of the cylinder plays a significant role in determining the overall height of the seat. If the gas jack is either excessively long or too short, it can result in your feet not reaching the ground, leading to discomfort and improper posture. When purchasing an office chair jack, it is essential to consider both the cylinder height and its weight capacity.
Gas jack sizes vary primarily in the length of the cylinder and its stroke. The standard sizes for seat jacks are 80, 100, 120, 200, and 270 mm. The 80 mm jack is generally used for executive and gaming chairs, while the 100 mm and 120 mm jacks are employed in the production of diverse office chairs.

Gas jack classification
Various types of chair gas jacks are categorized based on the thickness of their cylinder and column. They are classified into four distinct classes according to the load capacity of the gas cylinders.
A thicker jack cylinder typically indicates a higher weight capacity. Office chair jacks are classified into four categories: Class 1, Class 2, Class 3, and Class 4.

Extending the lifespan of the gas jack
Following basic instructions for daily use of office chair can significantly increase the life of the gas lift mechanism. Key considerations include:
Avoid placing excessive weight: Each gas lift has a defined weight limit. To prevent injury, it is vital to avoid exceeding the recommended weight capacity of your chair.
Scheduled inspections: Regularly check the product for any signs of deterioration, leakage, or damage. Promptly addressing any potential concerns can help prevent further issues and uphold safety standards. It is essential to understand that a leaking seat jack cannot be refilled with gas.
Maintenance: It is essential to regularly clean the gas cylinder using a soft cloth or sponge to prevent the accumulation of dirt and dust, which may hinder the jack's functionality. Avoid using any chemicals or cleaning agents that could potentially harm the product.
Lubrication: It is advisable to apply a modest quantity of lubricant, such as grease, to the moving components of the gas cylinder in order to minimize friction.
By following these maintenance tips, you can effectively prolong the operational life of your office chair jack, ensuring sustained performance and comfort in your chair.
Chair gas jack upgrade
To improve the performance of your office chair, upgrade to a higher-quality gas jack that offers more durability and smooth movement without making noises.
While choosing a new chair gas jack, pay attention to various factors that impact the quality of the item.
Look for a product made from superior material as they provide increased durability and extended longevity which enhance stability, guaranteeing that your chair remains both stable and secure.
When purchasing a gas jack, it is essential to consider its dimensions and the compatibility with your seat. Choose a jack that aligns with your base and mechanism.
In some cases, simply replacing the gas jack of an older chair can enhance its functionality, allowing for renewed use.
Gas cylinder replacement
In the event of a malfunction with the chair jack, replacement becomes essential. Specific signs that point to this problem are:
Making noise when moving vertically or rotating the chair
Gas cylinder’s sinking without applying pressure
Deficiency in stability and a state of laxity
The process of replacing the office chair jack is straightforward and does not necessitate the use of specialized tools.
To begin, turn the seat upside down and gently strike the base with a mallet to detach it from the jack.
Similarly, detach the cylinder from the mechanism. Exercise caution to avoid causing any damage to the base and mechanism while delivering impacts.
Position the new jack onto the base, ensuring it is properly seated.
Next, place the cylinder onto the mechanism and gently strike it with a hammer to secure it in position.
You can enhance the performance of your chair jack in four simple steps using just a mallet.
