Regarding the website products, Xiaobian will not talk about the gas spring, but explain other products, because the introduction of the gas spring has already been a lot in the front, so Xiaobian will change the topic so that everyone can learn at the same time.

The main differences between pneumatic and hydraulic support rods are:

The difference is that the medium used is different, pneumatic is the use of compressed air, hydraulic is hydraulic oil.

The difference is two: the bearing capacity is not the same, the pneumatic is below 1MPa, and the hydraulic is below 30MPa.

The difference is three: in terms of running accuracy, the hydraulic pressure is higher than the pneumatic one.
