before going further into the orientation and types of hydraulic seals, here are some things to consider when purchasing such industrial products. if you would like to buy the hydraulic motor,pg电子下载-pg电子游戏,hydraulic winch,gearbox,hydraulic steering unit products , ningbo zhongyi hydraulic motor co., ltd absolutely is your best choice.the diameters of the outer shaft, inner seal and housing bore should be specified. thickness and radial cross section should also be included in the list of considerations. service limits such as operating speed and pressure, vacuum rating and temperature should be dealt with accordingly.
various sealing orientations
there are various sealing directions for these industrial products. the first on the list is called a rod seal. a rod seal is a type of radial seal that is fit specifically into the housing bore. the sealing lip is found in contact with the shaft.
the second type is known as the piston seal. this is yet another type of radial seal and is a variation of the rod seal. instead of the sealing lip found in contact with the shaft, the lip goes in contact with the housing bore. it is in the shaft where the seal is pressed accordingly.
the other types of sealing orientations are symmetric and axial seals. a symmetric seal, as the concept implies, work symmetrical or equal to the rod and piston seals. the axial seal on the other hand, goes in contact or in axis with the housing component.
types of hydraulic seals
there are two categories for these industrial products. these are dynamic and exclusion seals. a dynamic seal is one that is used in order to separate a fluid from possible contaminants. it is utilized in order to put a gap between moving and non-moving surfaces like those found in piston ring applications. when considering dynamic seals, it is important to focus into a variety of dimensions like inside diameters, outside diameters, axial cross section, radial cross section and housing bore.
hydraulic seals are products that include types such as rod seals, flange packing and u-cups. they are specifically designed for applications that require high pressure such as those of hydraulic cylinders. it is said to have a wide array of orientations and different types.
