The oil seal is a mechanical component used to seal oil. It isolates the parts of the transmission component that need to be lubricated from the output components, so as not to let the lubricating oil leak. The oil seal is made of rubber. 

The oil seal is mainly used in the joint parts of two lubricating parts to prevent oil from seeping out, such as crankshaft oil seal, semi-shaft oil seal, transmission shell oil seal and so on. 

The skeleton oil seal is a typical representative of the oil seal. Generally speaking, the oil seal refers to the skeleton oil seal.
