● Total Length (Fully Extended):
Typically ranges from 350mm to 550mm, depending on the model and stroke length. The extended length determines how high the chair can be adjusted.
● Stroke Length:
80mm to 120mm: Typical for most standard office chairs and gaming chairs with normal height adjustment requirements.
120mm to 150mm: Often used in tall chairs or executive models where a larger range of height adjustment is needed.
150mm to 200mm: Used for extra tall chairs or chairs with adjustable height requirements for special ergonomic needs.
● Compressed Length:
The compressed length (when not extended) is typically between 200mm and 300mm, depending on the cylinder's design and stroke length.
A high-quality gas lift cylinder is a crucial component for adjustable chairs, desks, and other furniture that require pneumatic height adjustment. These cylinders are engineered to offer superior durability, smooth operation, and comfort for a wide range of applications, from office chairs to gaming chairs and ergonomic seating solutions.A gas lift cylinder operates through pneumatic pressure (usually nitrogen or air), allowing users to raise or lower the seat height effortlessly, ensuring the chair remains stable and secure at the desired height.
Force range | Weight Capacity: 100kg to 150kg: This range is common for high-quality office chairs and gaming chairs for average users. It ensures strong support for regular to heavy-duty use. 150kg to 200kg: Suitable for heavier users, executive chairs, and heavy-duty office chairs. These cylinders are reinforced for extra durability. Over 200kg: For specialized chairs designed to handle heavy weights or for industrial and commercial applications. |
Material | Cylinder body: steel (galvanized or sprayed) or stainless steel (corrosion resistant).Piston rod: hard chrome plated steel or stainless steel. |
Sealing material: high-quality fluororubber or polyurethane, effectively preventing dust and dirt from entering the gas spring, ensuring sealing and long-term use. | |
Operating Conditions | Applicable temperature range:Regular models: -20℃~+80℃; special models can withstand -40℃~+120℃. |
Installation
Distinguish between compression type (support force direction is consistent with installation direction) and tension type (reverse support)
Safety Features
Avoid using the machine at full stroke limit, and keep 10%~20% stroke margin to extend life. If frequent high-speed movement is required (such as a robotic arm), a high-response speed model should be selected.
Certification
Industrial applications require compliance with ISO 9001 or industry-specific standards (e.g. TS 16949 for the automotive industry)
● RoHS: Complies with environmental safety requirements, will not release harmful gases during long-term use, and protects the air quality in the car
● SGS: Independent product testing and verification, precise and controllable opening and closing force, easy and smooth operation
Customization options
● Customized options: Customized installation interface, providing a variety of standard joint options (ball head/fork head/eye head) Supports customized special joints, perfectly matching the original installation position
● Customized opening force, accurately calculate the required force according to the weight and size of the door panel, ensuring easy opening with one hand while maintaining a stable opening state
● Customized functional characteristics, optional anti-smashing rebound buffer function, customized safety design with limit protection
● Customized surface treatment and customized colors to perfectly match the car body
Gaming Chairs
● In gaming chairs, gas lift cylinders are used to adjust the chair's height based on the gamer’s preference. These chairs often have adjustable features to enhance comfort during extended gaming sessions. The weight capacity and stroke length of Class 3 cylinders are well-suited for gaming environments, offering stability and comfort for various body types.
Executive Chairs
● gas lift cylinders are also used in executive or managerial chairs, which often have a higher weight capacity and more robust construction. The smooth adjustment feature is especially important in these chairs to ensure users can adjust to a comfortable and ergonomic sitting position.
The pneumatic system enables quick and easy height adjustments, providing personalized comfort with minimal effort.
High-quality cylinders are available in various diameters and stroke lengths, making them compatible with many types of office, gaming, and executive chairs, as well as ergonomic furniture.
While a high-quality gas lift cylinder may come at a higher initial cost, its reliability and durability make it a worthwhile investment. The extended service life reduces the need for frequent replacements.
