Features & Benefits
Integrated dustproof outer edge provides an extra layer of contamination protection, blocking road dust, dirt and splash water from reaching the primary sealing lip and extending service life.
Rigid steel outer case creates a stable press fit in the housing bore, resists radial distortion and prevents seal rotation under vibration and dynamic shaft loads.
Double lip design with a single garter spring maintains uniform radial contact pressure on the shaft. The primary lip retains lubricating oil and grease, while the secondary lip adds a secondary barrier against fine particulate contamination.
Precision-bonded brown NBR rubber lip delivers reliable oil resistance and wear resistance, with good compatibility with mineral engine oils, gear greases and standard hydraulic fluids.
Precision finished outer diameter ensures consistent static sealing between the seal and housing, compensating for minor housing bore tolerances and surface imperfections.
Standard metric dimensions match common TBY-type housing specifications, making it suitable for direct aftermarket replacement in most standard rotary shaft assemblies.
This is an aftermarket replacement seal, not a genuine OEM part. Always verify shaft diameter, housing bore and application before ordering.
