　　Metric oil seal, also known as a shaft seal or rotary shaft seal, is a type of seal used to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. These seals are designed to prevent leaks while also preventing the ingress of contaminants such as dirt, dust, and water.

　　Metric oil seals are similar to other types of oil seals, but they are sized according to the metric system. This means that their dimensions are specified in millimeters rather than inches. Metric oil seals are commonly used in applications where metric-sized shafts and housings are used.

　　Like other types of oil seals, metric oil seals typically consist of a sealing element, a inner metal, and a spring. The sealing element is usually made of an elastomeric material such as rubber or silicone, which provides a flexible seal between the shaft and the housing. The inner metal provides structural support for the seal, while the spring helps to maintain contact between the sealing element and the shaft.

　　When selecting a metric oil seal, it is important to consider factors such as the operating conditions, the design of the seal, and the materials used. Different materials offer different levels of resistance to heat, chemicals, and other environmental factors, making them suitable for use in different applications.

　　Proper installation and maintenance are also important for ensuring reliable performance from a metric oil seal. The seal should be installed correctly to ensure proper contact between the sealing element and the shaft. Regular maintenance, including lubrication and inspection for wear or damage, can help to extend the life of the seal.
