The shaft on my chair is a bit over 1". Looks like about 1 3/32". Do you have a unit that will work?

I am looking for the same....I found a CC-8 inch, CC-9 inch and a CC-10 inch Pneumatic Gas Cylinder on EBay. URL if it works is... http://www.ebay.com/itm/CC-10-Office-Chair-Standard-Replacement-Spindle-Cartridge-Pneumatic-Gas-Cylinder-/380437215207?pt=LH_DefaultDomain_0&hash=item5893d337e7

Mine is a 1 1/2 inch pipe, but I'm sure you can use a reducer/adapter to fit.

I would be confident that it will work. They seem to be very consistent. I have yet to see a chair that uses anything very different. Just check the diameter as someone else suggested and length.

The shaft is 3/4 don't remember how long exactly for sure. I mounted a comet tourque converter clutch on it no Problem.

Mine is set at 36.5" with the extender. The extender makes it basically so I didn't have to unscrew it at all, 1/2" on each side. It may work, I would go buy one at the store (walmart) and make sure it will fit. Then, if it doesn't work returning it will be easier. I think it will probably work though.

All of the replys below answer the question. I think any bit with the notch in the shaft will work. There is probobly a manufacturing standard.

If the diameter is the same, it'll work. Does yours have a part number to search on amazon?

Original was probably 3/16th inch. I couldn't find that size so I read where 1/4 inch had been used by some that repaired there gravity chairs. It was a little tight but I believe it is much stronger. Time will tell.

Too short, working length on this unit more like 3 to 3 1/2 inches. Hope this helps.

A quick measurement on mine looks like the shaft center to the top of the unit is about 3" so it will be close. I am not sure where you are measuring from but normally there is a bit more clearance considering the wheel attached to the shaft is much larger in diameter than the shaft itself.

Hi, I just responded, but I think I am wrong. There is a heavy duty cylinder with a 1.1" shaft that is closer to the 28mm of your cylinder. Hope this helps.

I do not know. I am using a straight shaft. Sorry. Try the Tanaka web site. I think they have one.

I used this in a chair that wasnt a big and tall chair. You just need to make sure the opening in the base is what the description on the cylinder says it is for. I think it was a 2 inch opening.

I don't think so.....the diameter of the one I bought is approx 2" for the body. It tapers a little to fit tightly into the chair rollers but not to 1 1/2"

I ended up giving this to Goodwill because it didn't fit my whacker's shaft. Mine is too big. My lawn more repair guy is special ordering me one. Sorry.

I checked a picture of the office star 5500 and it appears that it should work but I suggest you check the dimensions of the cylinder you have. If the replacement is a little longer it really shouldn't really matter, but the width is crucial. It may be that all the chairs have the same width cylinders. Not sure about that, though. The job will be much easier if you get a dead blow hammer. A large rubber mallet, which I used, should work but a regular hammer may damage the chair and might not generate the pushing force needed to unseat the cylinder. If I need to do this in the future, I will get a 4 lbs dead blow hammer. There are several Youtube videos on this project. I found this one to be most helpful: http://www.youtube.com/watch?v=uiDby4FouwQ. Good luck. Walt

I seem to recall a kit on Amazon for just that purpose. Do a search for it. Probably will come up if you first bring up the chair and scroll down the same page.
