SKF 13857 Output Shaft Seal Radial Lip Seal

The SKF 13857 is a precision-engineered output shaft seal (radial lip seal) designed to prevent lubricant leakage and exclude contaminants at rotating shaft interfaces in automotive drivetrain applications. Manufactured under SKF's CR Seals heritage — formerly Chicago Rawhide — this seal meets or exceeds OEM specifications for a reliable, long-service-life replacement.

Key Features:

• OEM-quality construction with a steel-reinforced casing for dimensional stability and secure press-fit installation
• Precision sealing lip engineered from high-performance elastomer compound to maintain consistent contact pressure against the shaft journal
• Garter spring-loaded lip compensates for minor shaft misalignment and wear over the seal's service life
• Dual-purpose function — retains lubricant (gear oil or ATF) on the internal side while excluding dirt, moisture, and road contaminants from the bearing cavity
• SKF Bore Tite coating on the outer diameter provides a leak-free static seal against the housing bore without the need for additional sealant
• Manufactured to tight dimensional tolerances for correct fit in OEM seal bores

SKF CR Seals are trusted by professional technicians and OEM manufacturers worldwide. The 13857 is a direct-fit replacement output shaft seal suitable for transmission or transfer case output shaft applications. Always clean and inspect the housing bore and shaft journal surface before installation, and lightly lubricate the seal lip with clean gear oil prior to pressing into place.
