● Total Length (Fully Extended):
This can range from 350mm to 550mm, depending on the specific model and the stroke length of the cylinder.
● Stroke Length:
100mm to 150mm: This range is common for most standard office and gaming chairs, providing a good height adjustment range.
150mm to 200mm: This length is used for chairs requiring larger height adjustments, often in executive or heavy-duty chairs.
● Cylinder Diameter:
28mm: This size is often used for lighter duty chairs like basic office chairs or smaller gaming chairs.
35mm: This is the most common diameter for medium-duty chairs, including standard office chairs, gaming chairs, and task chairs.
A Class 3 gas lift cylinder is a commonly used component in office chairs, gaming chairs, and other adjustable seating furniture. It provides the ability to adjust the height of the chair smoothly and efficiently. The Class 3 designation indicates the cylinder's quality and durability, as it is designed for moderate to heavy use and is built to last longer than lower-class cylinders.
The Class 3 gas lift cylinder is designed with pneumatic gas pressure to allow users to adjust their seat height by raising or lowering the chair with minimal effort. This type of gas lift cylinder is typically found in medium to high-end office chairs and gaming chairs.
Force range | Weight Capacity: 100kg to 150kg: Suitable for most standard office and gaming chairs.1 50kg to 200kg: For heavy-duty chairs, executive chairs, or chairs meant for heavier users. |
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
Application
Adjustable Office Furniture
● In some adjustable office furniture solutions, gas lifts are used to control the height of desks or seating systems to suit both sitting and standing positions, improving flexibility and promoting health during work or gaming sessions.
Customization options
●Class 3 gas lift cylinders are commonly used in office chairs where adjustable height is a necessity. These cylinders provide users with the flexibility to find an optimal seating position for comfort and ergonomics. The smooth height adjustment is essential for promoting good posture, reducing strain, and improving productivity during long working hours.
By allowing easy height adjustments, these cylinders enable users to find the optimal seat height for ergonomic posture, reducing the risk of discomfort or health issues due to improper seating.
The Class 3 gas lift cylinder is widely used in various chair types, making it a versatile choice for both home and office furniture. It's suitable for executive office chairs, gaming chairs, office task chairs, and other adjustable-height furniture.
