Advanced Cassette Design: The RICH cassette seal features a self-contained system with an internal sliding surface, eliminating the need for specialized shaft hardening or surface finishing, and protecting the shaft from wear.
Premium FPM Construction: The use of Fluoroelastomer Rubber (FPM) ensures maximum resistance to high temperatures and chemical degradation from modern synthetic gear oils, significantly extending the maintenance intervals.
Superior Contaminant Exclusion: Engineered with multiple labyrinth sealing lips, this design provides a formidable barrier against water, mud, and road salt, making it ideal for long-haul and vocational heavy vehicles.
Reduced Friction and Heat: The internal pre-lubricated sealing geometry minimizes friction between the rotating components, reducing heat build-up and improving overall drivetrain efficiency.
Direct Mercedes-Benz Interchange: Precision-engineered as a direct replacement for OE references A0189973347 and 0219972847, ensuring a perfect fit and reliable performance in commercial vehicle axles.
