Oil seals can play the following important roles:

Preventing lubricating oil leakage: Oil seals play a sealing role in mechanical equipment to ensure that the lubricating oil inside the equipment does not leak. Lubricating oil is a necessity to maintain the normal operation of equipment, and oil seals can effectively prevent the loss of lubricating oil, so that it can play a role of lubrication and cooling inside the equipment.
Preventing the intrusion of dust and impurities: There are often a lot of dust, particles and impurities in the industrial environment, which cause friction, wear and failure inside the mechanical equipment. Oil seals can effectively block the entry of dust and impurities, protect sensitive parts of the equipment, and extend the service life of the equipment.
Reduce friction and wear: A sealed space is formed between the oil seal and the shaft, which reduces direct contact between metals and reduces the degree of friction and wear. Through the supply of lubricating oil, the energy loss of the equipment is reduced, and the efficiency and performance of the mechanical equipment are improved.
Oil seals have a wide range of applications in the industrial field, including but not limited to the following aspects:

Automotive industry: Oil seals are widely used in key parts such as automobile engines, gearboxes, differentials, etc. to ensure the normal operation and reliability of the lubrication system.
Engineering machinery: Oil seals are often used in key parts of engineering machinery equipment such as excavators and loaders, such as steering shafts and transmission shafts, to protect the equipment from the intrusion of dust and water.
Compressor and pump industry: Oil seals can be used in the sealing parts of various compressors and pumps to ensure that there is no gas or liquid leakage inside the equipment and maintain the efficient operation of the equipment. Oil seals are indispensable seals in mechanical equipment and can effectively protect the equipment from oil leakage and external dust intrusion.
