Tapered Roller Bearing - Outer Ring
Detroit Diesel

This outer race completes the tapered roller bearing set, enclosing the roller elements and pairing with the inner race to form a high-capacity load-bearing path in the powertrain. Manufactured from steel and sized to match the inner race, it shares the same dimensional footprint: 25 mm in width, 75 mm bore, and 115 mm outer diameter, enabling precise alignment and reliable engagement with the mating components in the housing. The steel construction provides excellent resistance to wear, enabling extended bearing life and consistent performance under fluctuating torque and speed conditions common to heavy-duty diesel operations. As the outer interface, it helps contain lubrication, maintain contamination exclusion, and support axial load distribution while accommodating radial forces from the rotating assembly. This part is integral to maintaining the integrity of the bearing system during high-load transients in start-stop cycles, hill climbs, and heavy acceleration scenarios. VMRS code 022-004-117 identifies its role within the tapered roller bearing family, aiding maintenance planning and stock management. There are no cross references listed for this item, so ensure compatibility with the corresponding inner race and roller set per OEM specifications. Category context situates it within bearing components essential to drivetrain assemblies.
