My curiosity led me to believe the 099-DX is a pneumatic cylinder not hydraulic. They are (or were) available in different bores.
Most Bimba cylinders I have experience with are not serviceable.
Actually you are correct with the actual use being air over hydraulic. The cylinder actually operates with oil on the bottom and air on the top and the oil reservoir has air pressure on the top. You can see the flow here; http://tinyurl.com/lxns8m6
