HITACHI Boom Cylinder Seal Kit  

Hitachi boom cylinder seal kit is an important part of the hydraulic cylinder, The function is to protect the boom cylinder from external dust, sand and damage. If your excavator arm cylinder has problems such as oil leakage, please replace or repair it in time. Design of hydraulic seals: In addition to selecting appropriate seals for piston seals, the design and manufacturing of hydraulic cylinders also have a significant impact on the performance of the seals. For example, the surface roughness and roundness of the cylinder block have a significant impact on the sealing effect of the sealing element. If the surface roughness of the cylinder block is too large or the roundness is not enough, it will cause the seals to not fully fit the surface of the cylinder block, leading to hydraulic oil leakage. Therefore, in the manufacturing process of hydraulic cylinders, it is necessary to ensure that the surface roughness and roundness of the cylinder body meet the requirements to ensur…
