The Bomag 92150009 Inner Ring is a genuine OEM component designed for Bomag BW 161 ADO-4, BW 161 ADO-5, BW 161 ADO-50, BW 190 ADO-5, and BW 202 ADO-50 tandem rollers. Sourced directly from Bomag, this inner ring meets the same manufacturing standards as the original part installed at the factory. Built to exact dimensional tolerances, this component installs directly into the bearing assembly without modification, restoring proper operation across the full range of compatible machines.
Key Features
- Genuine OEM Dimensional Accuracy — manufactured to Bomag's exact tolerances, ensuring the bearing assembly seats and loads correctly rather than introducing play or misalignment that could accelerate wear
- Direct-Fit Replacement — engineered to the original specification for part number 92150009, this inner ring drops into the existing bearing housing with no rework required
- Broad Tandem Roller Coverage — confirmed fit for BW 161 ADO-4, BW 161 ADO-5, BW 161 ADO-50, BW 190 ADO-5, and BW 202 ADO-50 tandem rollers
- Smooth Drum Rotation Restored — a correctly sized inner ring keeps the bearing's rolling elements properly aligned, enabling consistent drum speed and vibration transfer across the asphalt surface
- Long-Term Bearing Integrity — an OEM-grade inner ring prevents the uneven loading and heat buildup that a worn or undersized ring introduces, protecting the surrounding bearing components from premature failure
The inner ring is the interior race of a rolling-element bearing, providing the hardened raceway surface against which the balls or rollers travel as the shaft rotates. In a tandem roller's drum and drivetrain assemblies, the inner ring must maintain precise concentricity with the shaft to distribute load evenly and allow smooth, controlled rotation. When an inner ring becomes worn, pitted, or dimensionally out of spec, bearing noise, increased heat, and eventual seizure follow — leading to drum irregularities that affect compaction quality and can cause broader drivetrain damage if left unaddressed.
