　　Oil seals are critical components in many mechanical systems. They prevent the leakage of lubricants from gaps within machines and bearings. Two common types of oil seals are SC and TC seals. This article will explore the differences between these two types of seals.

　　SC Oil Seals

　　SC oil seals also known as Single Lip Oil Seals, are typically used in applications where there is no pressure or very low pressure. They have a single lip that seals radially and axially against the shaft. The lip is usually manufactured from an elastomer material, which provides excellent sealing properties. SC oil seals are commonly used in electric motors, gearboxes, and pumps.

　　TC Oil Seals

　　TC oil seals also known as Double Lip Oil Seals, have two sealing lips. The primary lip prevents the leakage of lubricants, while the secondary lip keeps dirt and other contaminants out of the system. This makes TC oil seals ideal for applications where contamination is a concern. They are often used in automotive applications, such as wheel bearings and transmissions.

　　Key Differences

　　The key difference between SC and TC oil seals lies in their structure and application. SC oil seals have a single lip and are used in low-pressure applications. On the other hand, TC oil seals have a double lip and are used in applications where contamination prevention is crucial.

　　Both SC and TC oil seals play vital roles in various applications. Understanding their differences can help you choose the right seal for your specific needs.
