(1) Bolt seal manufacturers tell you that choose the appropriate seal material and hydraulic oil, as well as adaptability to working temperature and compatibility with oil. (2) The bolt seal manufacturer tells you that the geometrical position accuracy (concentricity) of the sliding parts relative to the seal is high, the material is good (such as hard chrome plating) and the surface roughness is fine, which can prolong the service life.

(2) The bolt seal manufacturer tells you that the geometrical position accuracy (concentricity) of the sliding parts relative to the seal is high, the material is good (such as hard chrome plating) and the surface roughness is fine, which can prolong the service life.
The bolt seal manufacturers tell you that oil seals used in hydraulic pumps and motor journals not only require that the roughness of the sliding surface needs to be relatively small, but also require hard chrome plating on the surface, and the oil seal lip needs to be properly adjusted according to the specific situation during specific use. The radial spring force of the side makes it moderately tight. The bolt seal manufacturer tells you that and also protects the seal with a mounting sleeve or shim when installing, so that the lip does not roll over, twist, and cause the spring to slip out.
The above information is the bolt seal manufacturer's introduction of the key points of using seals, hope it helps you.
