the specifications and dimensions of skeleton oil seal are: 1*25*1, 25*47*1, 4*6*1, 5*72*12, 12*25*1, 26*47*1, 4*6*12, 5.
skeleton oil seal is a common mechanical seal, which is widely used in various bearings, hydraulic systems and lubrication systems to prevent lubricating oil leakage and external impurities from entering the equipment. The specifications and dimensions of skeleton oil seal include inner diameter, outer diameter and thickness, which determine the application scope and performance of oil seal.
The internal diameter of the skeleton oil seal is usually selected according to the shaft diameter. Generally speaking, the internal diameter should be slightly smaller than the shaft diameter to ensure a good interference between the oil seal and the shaft, thus achieving effective sealing. The external diameter size depends on the size and design requirements of the installation site. Generally speaking, the external diameter size is slightly larger than the through hole size of the installation site.
when selecting the skeleton oil seal, besides considering the specifications and dimensions, it is also necessary to select the appropriate material and structure according to the working conditions. For example, in high temperature, high pressure or chemical corrosive environment, skeleton oil seal with high temperature resistance and corrosion resistance should be selected. In addition, according to the different installation parts, the skeleton oil seal can be divided into different structural forms, such as inner-encapsulated rubber type, outer-encapsulated rubber type and exposed skeleton type.
it should be noted that the coding rules of skeleton oil seals may be different from manufacturer to manufacturer, so it is recommended to consult the sales staff in detail about the specifications and scope of application when purchasing, so as to ensure that the skeleton oil seals that meet the requirements can be purchased. In a word, the specification and size of skeleton oil seal should be selected according to specific application scenarios and installation requirements to ensure its good sealing performance and service life.
Features of skeleton oil seal:
1. Good sealing performance. The skeleton oil seal adopts special structure and material, which has good sealing performance, can effectively prevent the leakage of lubricating oil and the entry of external impurities, and ensure the normal operation of machinery.
2. High temperature resistance and corrosion resistance. The material of skeleton oil seal is usually fluororubber and other materials, which has the characteristics of high temperature resistance and corrosion resistance and can adapt to high temperature and high pressure working environment.
3. The structure is simple and easy to manufacture. The structure of skeleton oil seal is relatively simple, consisting of skeleton and lip, with relatively low manufacturing cost and easy maintenance and replacement.
4. Wide application range. Skeleton oil seal is suitable for lubrication sealing in various mechanical equipment, such as internal combustion engine, transmission and other fields, and is one of the substitutes of traditional oil seal.
5. Wear resistance and long service life. The lip part of the skeleton oil seal is made of special material and structure, which has good wear resistance and relatively long service life, and can ensure the long-term stable operation of the equipment.
