Oil seals are mechanical components used to seal oil (oil is the most common liquid substance in the transmission system, and also refers to general liquid substances). The friction part of the machine has oil entering it when the machine is running, so oil seals are used to prevent the oil from leaking from the gaps in the machine. In addition to oil, it is also necessary to prevent the leakage of water and chemical liquids, as well as the intrusion of dust and sand from the outside, so oil seals are also used at this time.
