💡 Why are TC double lip NBR oil seals with garter springs used in rotating equipment?
TC-style double lip oil seals are designed to improve sealing reliability in demanding environments.

• Primary sealing lip retains oil and grease inside the housing

• Secondary lip helps block dust and external contamination

• Garter spring maintains consistent sealing pressure over time

• NBR rubber performs well with lubricants across a wide temperature range

This seal offers dependable leakage control and long service life, helping rotating equipment stay cleaner, better lubricated, and ready for steady operation.
