What is the temperature range for TC oil seal?
TC oil seals, also known as lip seals, are commonly used in various industries to prevent the leakage of fluids, such as lubricants or hydraulic fluids, in rotating or reciprocating shafts. The temperature range for TC oil seals depends on the materials used and the design of the seal.
In general, TC oil seals can withstand temperatures ranging from -40°C to 200°C (-40°F to 392°F). However, it is important to note that these temperature limits are not absolute and can vary depending on several factors.
The temperature limits of TC oil seals are primarily determined by the materials used for the sealing lip and the metal case. The sealing lip is typically made of elastomers such as nitrile rubber (NBR), fluoroelastomers (FKM), or silicone rubber (VMQ). These materials have different temperature resistance properties.
Nitrile rubber (NBR) is the most commonly used material for TC oil seals and has a temperature resistance range of -40°C to 120°C (-40°F to 248°F). It provides good resistance to oil, fuel, and grease, making it suitable for a wide range of applications.
Fluoroelastomers (FKM), such as Viton, have a higher temperature resistance than NBR. They can withstand temperatures up to 200°C (392°F) and offer excellent resistance to oils, fuels, and chemicals. This makes FKM seals suitable for applications that involve higher temperatures or more aggressive fluids.
Silicone rubber (VMQ) is another material used for TC oil seals, especially in applications that require extreme temperature resistance. Silicone seals can withstand temperatures ranging from -60°C to 200°C (-76°F to 392°F), making them suitable for both low and high-temperature environments.
The metal case of TC oil seals also contributes to their temperature resistance. The case is typically made of steel or stainless steel, which have good heat dissipation properties and can withstand higher temperatures without deforming or losing their sealing effectiveness.
The temperature range of TC oil seals is crucial in determining their suitability for specific applications. In environments where extreme temperatures are encountered, selecting the right material and design of the seal is crucial to ensuring optimal performance and preventing seal failure.
In conclusion, the temperature range for TC oil seals varies depending on the materials used for the sealing lip and the metal case. Nitrile rubber (NBR) seals have a temperature resistance range of -40°C to 120°C (-40°F to 248°F), while fluoroelastomers (FKM) and silicone rubber (VMQ) seals can withstand higher temperatures up to 200°C (392°F). The temperature resistance of TC oil seals is an important consideration in various industries to prevent fluid leakage and ensure reliable operation of rotating or reciprocating shafts.
