Hydraulic cylinder seals are a key part of the hydraulic system, which converts mechanical power into hydraulically transmitted power. The most important function of the seals is to prevent oil from leaking from the cylinder, which could cause malfunctions or damage to the system. Seals must also withstand high-pressure hydraulic fluid and wear, so they must be made of high-quality material and designed to withstand long-term use. A well-designed and installed sealing system ensures a long service life and smooth operation of the cylinder.
