Who can tell me the advantages and disadvantages of double cylinder?

The dual-force cylinder has the characteristics of reliable operation, good durability, low lifting pressure, good sealing performance, stable movement, beautiful appearance and strong interchangeability. By installing PTFE support ring on the piston, the sealing performance of the piston can be kept consistent during movement, thus reducing wear and prolonging service life. The buffer device adopts a new foreign structure, which can play the role of one-way valve and make the cylinder structure more compact and reasonable.
