  • Drivetrain Integrity: Specifically engineered for the 74 mm shafts found in propshafts and differential drives, ensuring consistent radial pressure and a 100% leak-proof interface.
  • High-Grade NBR Durability: Formulated for maximum resistance to mineral oils and greases, the NBR compound maintains its sealing properties across a standard operating temperature range of -40°C to +100°C.
  • Robust Contaminant Exclusion: The specialized multi-lip labyrinth architecture acts as a shield against dry dirt, mud, and road salt, significantly reducing the wear on internal bearings and axle components.
  • Direct OEM Interchange: Precision-engineered to match the technical specifications of CLAAS and Renault Trucks reference 7700021091, guaranteeing a reliable fit for professional fleet maintenance.
