Sealing Performance And Influencing Factors Of Oil Seals

Factors and mechanisms affecting sealing performance
The influencing factors of sealing performance include temperature, pressure, and shaft speed. Oil seals maintain reliable sealing through lip design and springs to cope with changes in these factors.
The selection of raw materials is crucial for the design of oil seals. The raw materials for oil seals mainly include metal frames, springs, and rubber sealing lips. According to different usage environments, different rubber materials can be selected to meet the requirements of sealing performance. Nitrile rubber is one of the most commonly used oil resistant rubbers, with wide applicability and cost advantages.
Oil seal design and sealing medium used
When designing oil seals, the requirements of different sealing media have been fully considered. Its applicable medium range is wide, including mineral lubricating oil, lubricating grease, synthetic lubricating oil, and lubricating grease. In addition, it can effectively seal DIN51524 hydraulic oils used in industrial production, as well as VDMA24317 and VDMA24320 high flame retardant hydraulic oils. For silicone oils with low lubrication characteristics, oil seals also have sealing capabilities. In special circumstances, even when facing corrosive media such as acids, bases, and organic solvents with low lubricity, oil seals can still perform their sealing function.
Usage conditions and restrictions
The performance of oil seals depends on appropriate usage conditions, including temperature, pressure, and installation process. Choosing appropriate oil seals is crucial for the normal operation of equipment, and oil seals should not be used under conditions that exceed their design capacity.
