In the field of mechanical engineering, oil seals play a key role in preventing leakage of lubricants from machinery and vehicles. Among all kinds of oil seals, TC and TCV skeleton oil seals are commonly used, each with its own unique characteristics and uses.
TC, also known as double lip oil seal, is characterized by having a double sealing lip. The primary lip prevents oil leakage, while the secondary lip prevents dust and dirt from entering the system. This dual protection makes TC oil seals a popular choice for applications where contamination is a concern.
TCV oil seals are known for their single lip and additional dust lip. The main lip provides a seal, while the dust lip acts as a barrier against external contaminants. TCV oil seals are commonly used in high-speed rotating machinery due to their excellent sealing properties and high temperature resistance.
The structural differences between TC and TCV seals result in different performance characteristics. TC oil seals feature a double-lip design that provides superior sealing performance and better protection against dust and dirt. However, they may not perform well in high-speed applications due to the increased friction of the accessory lip.
In contrast, TCV oil seals have a single-lip design, which is more suitable for high-speed applications. The single lip reduces friction and allows the seal to perform better at higher speeds. However, compared to TC oil seals, the disadvantage is that they are slightly less resistant to dust and dirt.
TC and TCV skeleton oil seals have their unique advantages and are suitable for different applications. The choice between the two depends on the specific requirements of the application, such as operating speed and the degree of environmental contamination.
