Product details
Product Overview
This TB 44x59x9mm metal cased double lip oil seal is a standard radial rotary shaft seal designed for automotive and light industrial sealing applications. Manufactured with precision-bonded NBR rubber and a rigid steel outer case, it delivers reliable fluid retention and contamination protection under continuous rotation and vibration.
Ideal for aftermarket replacement, fleet maintenance and industrial MRO. All dimensions follow standard metric tolerances for direct interchange with common TB-type housings.
Key Features & Benefits
- Rigid steel outer case: Provides stable press fit in the housing bore, resists radial distortion and prevents seal rotation under vibration and dynamic loads.
- Double lip with garter spring: Maintains consistent radial contact pressure on the shaft. Primary lip retains oil and grease; secondary lip blocks dust, splash water and light contaminants.
- NBR nitrile rubber lip: Offers excellent compatibility with mineral oils, gear greases and standard hydraulic fluids. Balanced wear resistance for typical automotive and light industrial duty cycles.
- Precision finished OD: Ensures reliable static sealing between seal and housing, compensates for minor bore tolerances and surface imperfections.
- Standard metric size: 44mm ID × 59mm OD × 9mm height. Fits common automotive wheel hub, water pump, generator and auxiliary shaft housings.
This is an aftermarket replacement seal, not a genuine OEM part. Always verify shaft diameter, housing bore and application before ordering.
