Cylinder sealing is an important component that prevents leakage (internal and external) of the working medium (hydraulic oil) and prevents foreign objects (such as air, dust, and water) from entering hydraulic components and systems.

 

Although seals are auxiliary components in hydraulic equipment, the quality of seals and sealing devices is one of the key factors directly affecting the normal operation of hydraulic systems. The quality of seals has to some extent constrained the improvement of the performance and reliability of hydraulic components and systems, the length of their service life, and the key factors affecting the overall quality and level of the machine, as well as its participation in international competition.

 

After more than 20 years of hard work, Jiulong Sealing has gone through the process of introduction, digestion, absorption, and continuous innovation. Nowadays, its products have been applied to multiple industries such as engineering machinery, metallurgy and mining, and machine tool equipment. Some products have already replaced imports, truly achieving the transformation of following, running together, and leading the way.
