1. When installing the O-ring, please do not pull it to the point of permanent deformation, and do not roll it while installing it. You need to lower it gently to avoid twisting and leaking oil.


2.When installing, the opening of the sealing ring should first face the pressure oil chamber. When the pressure ring presses the sealing ring, the support ring can deform the sealing ring and act as a seal.


3. After disassembly, all O-rings and PTFE rings should be replaced with new ones.


4.If the sealing device needs to cooperate with the sliding surface, it should be coated with a certain amount of hydraulic oil.

Finally, after assembly, the piston assembly should move without any sense of stagnation or uneven resistance. After the piston and piston rod are assembled, try to measure their coaxiality and straightness over the entire length to see if they are out of tolerance. After being assembled as required, several reciprocating movements should be performed under low pressure to eliminate gas in the cylinder.
