What are the Differences Between TC, TB, TCY, and SC Oil Seals?
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 t...
