Integrated Combi Labyrinth: The unitized design features a sophisticated multi-lip barrier that protects the primary sealing lip from external particles and moisture, significantly increasing service life in harsh operating environments.
High-Grade NBR Resilience: Formulated for maximum compatibility with mineral-based lubricants and gear oils, the NBR compound maintains its elasticity and structural integrity across a wide thermal range.
Precision dual-height Fit: The 13/17 mm architecture ensures accurate axial positioning and a superior seal against the housing bore, preventing oil migration and ensuring a stable fit under mechanical vibration.
Aggressive Environmental Shielding: Acts as a robust physical barrier for internal components, protecting critical bearings from premature wear caused by dust, water, and abrasive field debris.
Goldoni Precision Compliance: Precision-manufactured to match the exact technical standards of Goldoni reference 6220165, guaranteeing a reliable factory-standard replacement.
