SF1 Combi Technology: The unitized SF1 design merges the sealing lip and a protective labyrinth into a single metal housing, creating a superior barrier against external contaminants that cause premature drivetrain wear.
Precision Axle Engineering: Specifically optimized for the 45 mm shaft diameter found in JCB backhoes and New Holland tractors, ensuring a stable interference fit and consistent radial pressure.
High-Grade NBR Resilience: Formulated for maximum resistance to mineral gear oils and greases, the NBR compound maintains its elasticity and sealing integrity under high-torque mechanical stress.
Aggressive Environmental Shielding: The multi-lip labyrinth architecture acts as a robust shield against moisture and abrasive grit, significantly extending the service life of internal hub bearings.
Direct OEM Interchange: Precision-engineered to match the exact technical standards of JCB reference 90450009 and New Holland 5135990, guaranteeing a reliable factory-standard fit.
