Confirm
Price, lead time, sample plan, packaging and required documents are agreed.
Deliver
Production, inspection and export coordination proceed against the confirmed order.
What makes a gas lift the right fit?
Start with the movement your chair needs. Then check the dimensions, actuation and loading conditions together. A model name or class alone cannot establish compatibility.
Stroke and seat height
Stroke is the available vertical travel, not the total length of the gas lift. Specify the minimum and maximum seat height you need, together with the space available beneath the seat mechanism.
Closed length and connections
Check closed and extended lengths, tube diameter, cone engagement and valve actuation. A matching diameter alone does not guarantee a correct fit. Confirm the drawing and test the sample in the actual mechanism and base.
Force and working load
Gas force in newtons (N) and user weight in kilograms (kg) describe different things. Share the intended use and loading conditions so the force and complete chair configuration can be reviewed together.
Class and test requirements
Class 2, 3 or 4 is one specification input. It does not by itself certify the complete chair or define its safe user weight. Request the applicable test evidence for the exact configuration and destination market.
Black or chrome finish
Specify the finish, the amount of exposed tube and the intended environment. Black and chrome options vary by family. Any special surface performance requirement should be stated in the enquiry.
Quantity, packaging and OEM
Include the order quantity, forecast, destination, drawing and sample acceptance requirements. Marking, packaging, minimum order quantity and production lead time are agreed for the requested configuration.
Need a specific stroke, force or finish?
Send the application, target dimensions, expected quantity and destination country. Our team will confirm the manufacturable configuration.
