single lip oil seal

The SC type oil seal, also known as a single lip oil seal, is a rotary seal commonly used for sealing fluids or preventing contaminants from entering mechanical components. It typically consists of a metal case with a rubber or elastomer lip that makes contact with the rotating shaft. The TC type oil seal, also known as a double-lip oil seal, incorporates an additional wiper lip along with the primary sealing lip. The wiper lip acts as a protective barrier, wiping away dirt, debris, and other contaminants from the shaft surface before they can reach the sealing lip. This design offers enhanced protection against external contaminants, making TC type oil seals suitable for applications exposed to harsh environments or contaminants.
