The condition of the skeleton oil seal mold oil seal can work

Lubricating oil: During the use of lubricating oil, not only the material itself will change, but also the additives that act as lubricating will change. After the decomposition and decomposition, heat, oxides, etc. will be generated. These decomposition products may produce very much to the sealing material. Great influence, so we have to consider it.

Temperature: Time and temperature can cause irreversible changes in the action of the sealing material and the lubricating oil itself and between them. At low temperatures, the rubber material temporarily hardens, the viscosity of the lubricating oil temporarily increases, the main lip may leak, the seal ring may be cracked and abnormally worn, and the hardening of the material may cause the main lip to follow the axis to change, This causes a low temperature leak. The rubber body will also harden under continuous high temperatures. The effect of the shaft interference and pressure on the oil seal will also cause the heating of the contact surface between the rubber lip and the shaft. The higher rotation speed and pressure will also cause the temperature of the main lip to rise, and the lip contact surface and the lubricating oil. A large temperature difference is formed between them, so that the viscosity of the lubricating oil under the lip changes, which also affects the sealing effect of the sealing ring.
