　　Oil seal, also known as a shaft seal, is a type of mechanical seal commonly used in various machines and equipment to prevent lubricating oil or other fluids from leaking out. Oil seals are typically made of rubber, metal, and other composite materials, and have properties such as wear resistance, oil resistance, and high temperature resistance, which enable them to adapt to various harsh environments.

　　Oil seals are mainly used in the shaft part of machinery and equipment, and they can prevent lubricating oil from leaking from the sealing area of the shaft, as well as prevent impurities such as dust and water from entering the equipment, thus ensuring the normal operation of the equipment. Oil seals can also reduce the wear and friction of the shaft, thereby extending the life of the equipment.

　　Oil seals generally consist of an inner shell, an outer shell, and a sealing lip. The inner shell is fixed on the shaft, the outer shell is fixed on the bearing seat or the machine equipment, and the sealing lip contacts the surface of the shaft, forming a sealing area. When the shaft rotates, the sealing lip of the oil seal contacts the surface of the shaft to form a sealing area, preventing lubricating oil or other fluids from leaking out. When the shaft is stationary, the sealing lip of the oil seal can maintain its original shape to protect the shaft and the sealing lip from wear.

　　Oil seals are a commonly used mechanical seal that prevent lubricating oil or other fluids from leaking out, protecting the normal operation of the equipment. Oil seals have excellent properties such as wear resistance, oil resistance, and high temperature resistance, which enable them to adapt to various harsh environments. Proper selection and installation of oil seals can effectively extend the life of equipment and reduce maintenance and replacement costs.
