Is there a difference between TC, TB, TCY, and SC oil seal ?
Oil seal is a device used in various mechanical equipment to prevent oil leakage and dust intrusion. They are usually composed of a metal skeleton and a rubber lip tightly attached to the shaft. There are various types of oil seals, and in this article, 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 lip and a spring that enhances sealing pressure. The difference between them is that the TC oil seal has a dust lip on the outside and a rubber coating on the metal casing, while the TB oil seal does not have a dust lip and the metal casing does not have a rubber coating. TC oil seals are suitable for applications with dust or dirt in the environment, such as agricultural machinery, engineering machinery, etc. TB oil seals are suitable for applications without 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 lip and a spring that enhances sealing pressure. Their difference is that the TCY oil seal has a dust lip on the outside and a double-layer metal shell with rubber coating on both sides, while the SC oil seal does not have a dust lip and has a rubber coated metal shell. TCY oil seals are suitable for situations with high oil chamber pressure or temperature, such as hydraulic systems, compressors, etc. SC oil seals are suitable for situations with low oil chamber pressure or temperature, such as hydraulic systems, compressors, etc. Such as water pumps, fans, etc.
TC, TB, TCY, and SC oil seals are four types of skeleton oil seals, each with a different structure and function. All are internal rotary oil seals, which can prevent oil leakage and dust intrusion. However, according to the lip design and shell design, they have different characteristics and applications. By understanding their differences, we can choose the appropriate oil seal type for our equipment.
