　　Oil seals are devices that prevent oil leakage and dust intrusion in various mechanical equipment. They are usually composed of a metal skeleton and a rubber lip that are tightly attached to the rotating shaft. There are many types of oil seals, but in this essay, I will focus on four common types: TC, TB, TCY and SC.

　　TC and TB oil seals are similar types of oil seals. They have a single lip and a spring that enhances the sealing pressure. The difference between them is that TC oil seals have a dust-proof lip on the outside and a rubber-coated metal case, while TB oil seals do not have a dust-proof lip and have a metal case without rubber coating. TC oil seals are suitable for applications where there is dust or dirt in the environment, such as agricultural machinery, construction machinery, etc. TB oil seals are suitable for applications where there is no dust or dirt in the environment, such as gearboxes, pumps, motors, etc.

　　TCY and SC oil seals are also similar types of oil seals. They have a single lip and a spring that enhances the sealing pressure. The difference between them is that TCY oil seals have a dust-proof lip on the outside and a double metal case with rubber coating on both sides, while SC oil seals do not have a dust-proof lip and have a rubber-coated metal case. TCY oil seals are suitable for applications where there is high pressure or high temperature in the oil chamber, such as hydraulic systems, compressors, etc. SC oil seals are suitable for applications where there is low pressure or low temperature in the oil chamber, such as water pumps, fans, etc.

　　TC, TB, TCY and SC oil seals are four types of skeleton oil seals that have different structures and functions. They are all inner-type rotary oil seals that can prevent oil leakage and dust intrusion. However, they have different characteristics and applications depending on their lip design and case design. By understanding their differences, we can choose the most suitable type of oil seal for our equipment.
