Mercedes 3872620893 Sealing Rings: Tamper-Proof Transmission System
High-precision sealing for responsible mobility
THE ring stop seal It guarantees the integrity of your rotating components, preventing lubricant leakage and the intrusion of external contaminants. Reference 3872620893, designed specifically for transmission architectures Mercedes-Benz (gearbox and axle systems), ensures impeccable hydraulic retention. With a view to sustainable maintenance, This high-performance seal reduces parasitic friction and prevents premature wear of shaft bearings, thus optimizing the longevity of your drivetrain.
True to our commitment to technical transparency, This original component guarantees total elastomeric resilience, meeting the requirements of logistics fleet managers the most rigorous.
Technical Specifications & Friction Resilience
Cutting-edge engineering for reliability that meets heavy industry standards:
-
High Recovery Capacity Elastomer: Developed according to rigorous chemical protocols, meeting compression requirements inspired by high-performance standards API CH4/SJ And MB 228.1 / 229.1.
-
Interactions with the Lubricant: The sealing lip is designed to function in contact with a high-quality base oil endowed with a strong viscosity index, ensuring constant flexibility of -40°C à +130°C.
-
Maximum Thermal Resilience: The polymer material displays a high sublimation point technique, preventing any premature hardening or vitrification under the effect of thermal cycles of transmission.
-
Zero-Leak Geometry: The retaining ring is profiled and calibrated with micrometric precision to perfectly match the tolerances of the shaft and the housing.
Your Advantages
