Hydrodynamic Swirl Technology: The integrated Left-hand Twist design features precision grooves that pump lubricant back toward the internal reservoir, providing a superior sealing effect during operation.
High-Grade NBR Resilience: Formulated for maximum compatibility with automotive axle lubricants and mineral oils, maintaining its elasticity and structural integrity across standard thermal ranges.
Specialized LHTBSY Architecture: The dual-height profile (11 mm / 20.3 mm) ensures accurate axial positioning and a robust barrier against the ingress of external dust and moisture.
Precision Engineering: Optimized for 40 mm shaft diameters to provide consistent radial pressure, reducing friction while preventing oil migration in critical drive components.
Nissan/Infiniti Precision Compliance: Precision-manufactured to match the exact technical standards of OE reference 38189AR001, guaranteeing a reliable factory-standard replacement.
Transparency Note: This component is manufactured under the RICH brand. The listed dimensions and references are used for identification and do not imply affiliation with other manufacturers.
