The Features Of Petroleum Rubber Oil Seal

Mar 12, 2022

The rubber oil seal is mainly composed of four parts, namely: the sealing end face (the combination of 

the moving ring and the static ring), the auxiliary oil seal, the buffer compensation part (composed of 

elastic elements), and the transmission part that enables the moving ring to rotate with the shaft. From 

the characteristics of petroleum rubber oil seal, it is mainly manifested in its long service life, high 

reliability, small leakage, low power consumption, and no need for frequent maintenance, small wear on 

the shaft, and can be well adapted to the actual situation. For high sealing requirements in the 

production process, such as high temperature, low temperature and vacuum environment, or various 

types of highly corrosive substances, special sealing measures must be adopted. For the sealing of 

equipment and devices, the rubber oil seal is the key, but due to its relatively complex structure of the 

rubber oil seal, even if there are many sealing advantages, in view of its high requirements in the process 

of manufacturing and installation, it leads to cost increase, and the technical requirements for 

maintenance personnel will be very high. Therefore, it is very necessary to ensure the reliability of sealing work to prolong the service life of petroleum rubber oil seals.
