Tapered Roller Bearing - Inner Ring
Detroit Diesel

In heavy-duty diesel powertrain applications, this inner race of a tapered roller bearing assembly provides critical support for rotating components by accommodating both radial and axial loads transmitted through the drivetrain. Crafted from steel and finished to tight tolerances, it features a 25 mm width, a 75 mm inner diameter, and a 115 mm outer diameter, ensuring precise seating within the mating outer race and housing. The robust steel construction delivers high load capacity, fatigue resistance, and durability under the demanding conditions typical of Detroit Diesel platforms, helping to extend service life and reduce unplanned downtime. When paired with the corresponding outer race and roller set, the inner race contributes to smooth, efficient operation by evenly distributing loads along the roller elements, minimizing friction, and controlling heat generation during high-speed rotation. Its compact width supports compact gear trains and tight engine compartments, aiding accurate shaft alignment and reliable seal performance. VMRS classification 022-004-117 places this component within the tapered roller bearing family, facilitating correct ordering and maintenance planning alongside other powertrain wear components. Cross references are not listed for this item, so verification against OEM specifications and the mating outer race is recommended to confirm full compatibility. Category context identifies this part as a bearing component within drivetrain assemblies.
