When it’s time, you need to replace your office chair cylinder. In this article, FittingChairs will guide you step-by-step on how to replace office chair cylinder.
Are office chair cylinders universal?
Most office chair bases are universal and can fit most office chairs. As long as the office chair base has a 50mm gas lift center hole, it can be able to house a standard office chair gas cylinder.
However, office chair bases have different diameters. They range from 23 to 28 inches. The larger the diameter, the more stability it provides for the user.
You should pay more attention to this part, as the base is the foundation of every swivel chair.
You should find an office chair base made of high-grade nylon, which is superior to aluminum, because it has more ability to flex so it doesn’t crack or break.
How to choose the correct gas cylinder for an office chair?
In general, an office chair gas cylinder has two parts. The top part is the gas spring, which holds the pressurized gas and oil for lubrication.
The gas spring’s top-end holds the button that lowers or raises the chair upon pressing.
If you want to know which gas cylinder you’ll need, you have to measure the stroke first. To properly measure the stroke, you need to:
- Move your chair to a wall and lower it all the way down
- Use the top of the backrest as a template and mark the lowest setting of the chair
- Raise the chair all the way up
- Mark the highest setting
- Measure the distance between the lowest and the highest setting
The standard travel for most chairs is 4 to 10 inches.
If you measure 4 inches, that means it has a 4-inch stroke gas cylinder and can travel four inches from the lowest to the highest setting.
For 4.25 inches, a standard cylinder of S6222 would be ideal. If it’s 10 inches, a S6120-HD would be perfect.
