Office Chair Gas Lift Cylinders – Precision Lift, Durable Performance
Changzhou Andefu Gas Spring Co., Ltd. (ADF) is a direct Office Chair Gas Lift Cylinders manufacturer based in Changzhou, China. Since 2007, we have focused on the research, development, and production of gas springs and cylinders for seating, automotive, and industrial applications. Our integrated factory and trade operation means you work directly with the production source, not a middleman.
Our ADF series office chair gas lift cylinders are engineered for smooth height adjustment, reliable positioning, and long service life. With outer tube lengths from 155 mm to 710 mm and load capacities from 300 to 500 Newtons, the range covers compact task chairs to heavy-duty executive seating. Every unit includes a built-in damping mechanism for quiet, controlled motion.
Available Models in the Range
We supply two primary configurations to match different chair designs and performance requirements:
- Standard Height Heavy Duty Office Chair Gas Lift Cylinders – Designed for daily office use and higher load expectations. These cylinders offer robust construction, consistent damping, and a wide range of stroke lengths. Ideal for ergonomic chairs, task chairs, and multi-shift environments.
- Black/Electroplating Surface Adjustable Office Chair Gas Lift Cylinders Replacement – A versatile option for replacement and aftermarket needs. Available with classic black spray or high-end electroplating finishes, these cylinders fit most standard chair bases and provide smooth, adjustable height control.
Both models share the same core engineering: precision-machined tubes, sealed gas chambers, and integrated damping. They are suitable for boss chairs, office chairs, and swivel seating where free raising, lowering, and positioning are required.
Engineering and Configuration Flexibility
We understand that each chair platform has unique dimensional and performance targets. Our cylinders are available with outer tube length (A) from 155 mm to 710 mm, while inner tube length (B) and connection diameter (C) vary by model. This allows us to match your existing chair base, seat pan, and tilt mechanism without redesign.
Force output is calibrated between 300 N and 500 N, covering typical office seating loads. The built-in damping adjustment ensures smooth motion regardless of the user's weight, reducing the risk of sudden drops or jerky movement. Surface treatment options include black spray for a matte, durable finish and electroplating for a polished, corrosion-resistant appearance.
Application Fit and Integration
Our office chair gas lift cylinders are used in a wide range of seating products:
- Executive and management chairs
- Ergonomic task chairs
- Conference and visitor seating
- Swivel chairs and stool applications
- Replacement and aftermarket cylinders
We also supply related gas spring products for bar stools, automatic lift systems, and support applications. If your project requires a different stroke, force, or mounting interface, our R&D team can develop a custom solution based on your drawings or samples.
Quality Control and Production Capability
Our factory operates advanced automatic production lines and dedicated testing equipment. We control the entire process from material selection to final inspection, ensuring each cylinder meets consistent quality standards. Our annual production capacity exceeds 20,000 tons, allowing us to handle both small pilot orders and large-volume wholesale contracts.
We have exported to Southeast Asia, North America, Europe, and other regions, building a reputation for reliable delivery and stable product quality. Our team includes experienced engineers and technical staff who support you from sample development through mass production.
Customization and OEM Support
We are primarily a custom manufacturer. You can send us your drawings, samples, or a detailed specification, and we will produce cylinders that match your exact requirements. Standard parts are also available for common office chair configurations, which can reduce lead time and tooling costs.
Our in-house capabilities include laser cutting, CNC machining, automated assembly, and comprehensive testing. We can adjust tube length, stroke, force, damping characteristics, and surface finish to suit your application. For high-volume programs, we offer dedicated production lines and packaging options.
Information We Use to Configure Your Solution
To prepare an accurate quotation and technical proposal, we need the following project information:
- Chair type and target application (office, executive, task, etc.)
- Required height adjustment range and overall cylinder length
- Load capacity or user weight range
- Mounting dimensions: tube diameter, connection type, and end fittings
- Surface finish preference (black spray, electroplating, or custom)
- Expected annual volume and delivery schedule
- Any relevant standards or certifications for your market
With this information, we can recommend the most suitable model from our standard range or initiate a custom design. We will provide samples for your testing before mass production, and we support you with technical documentation and after-sales service.

Frequently Asked Questions
What is the typical lead time for samples and mass production?
Sample lead time is usually 7–15 days after we confirm the specification. Mass production lead time depends on order quantity and current schedule, but we will provide a clear timeline with your quotation.
Can you match an existing cylinder from a competitor?
Yes. Send us the sample or detailed drawings, including tube length, diameter, stroke, force, and mounting fittings. Our engineering team will reverse-engineer or adapt the design to meet your requirements.
Do you offer custom force calibration for different user weights?
We can adjust the gas pressure and damping to achieve a specific force curve. Tell us the target load range and we will calibrate the cylinder accordingly.
What surface finishes are available for the outer tube?
We offer classic black spray and high-end electroplating as standard. Other finishes, such as chrome or custom colors, can be developed for larger orders.
Do you provide test reports or certification documents?
Yes, we can provide material certificates, inspection reports, and performance test data for each batch. If your market requires specific certifications, we will discuss compliance during the quotation phase.
How do you handle packaging and shipping for export?
We pack cylinders in cartons or pallets according to your requirements. We are close to Shanghai Port and Nantong Port, so sea freight is efficient. We can also arrange air freight for urgent orders.
