The Bomag 92020512 Inner Ring is a genuine OEM component designed for Bomag tandem rollers across the BW 141, BW 151, BW 161, BW 190, BW 191, BW 202, BW 203, BW 205, and BW 206 series. Sourced directly from Bomag, this inner ring delivers the exact dimensional tolerances and material grade required for proper bearing assembly function. Confirmed fitment spans generation -4 and -5 variants including AD, ADH, ADO, AC, and AM configurations, covering models such as the BW 161 AD-4, BW 202 AD-5, BW 190 AD-5, BW 206 AD-5, and BW 141 AD-5, among many others. When it comes to rotating components, OEM provenance is the most reliable way to ensure your machine returns to full operating condition.
Key Features
- OEM-Spec Dimensional Accuracy — manufactured to Bomag's exact tolerances, ensuring proper load distribution and seating within the bearing assembly
- Drop-In Replacement — matches the original inner ring geometry for straightforward installation without rework or re-machining
- Broad Tandem Roller Coverage — fits BW 141, BW 151, BW 161, BW 190, BW 191, BW 202, BW 203, BW 205, and BW 206 tandem rollers across -4 and -5 generation variants, including AD, ADH, ADO, AC, and AM builds
- Protects Adjacent Components — a correctly fitted inner ring prevents uneven bearing wear that can migrate damage to shafts, housings, and surrounding drivetrain parts
- Genuine Bomag Part — part number 92020512 is an authenticated OEM component, providing confidence that the specification matches your machine's original design
The inner ring is the hardened, precision-ground core component of a rolling-element bearing assembly. It fits tightly onto a shaft and provides the inner raceway along which the bearing's rolling elements travel, transmitting rotational load between the shaft and the outer race. When an inner ring becomes worn, cracked, or out-of-round, it causes abnormal vibration, heat buildup, and accelerated bearing failure — conditions that can quickly escalate into shaft damage or drivetrain downtime on a tandem roller working on an asphalt compaction crew. Replacing this part with a correctly specified OEM component restores smooth, controlled rotation and protects the integrity of the surrounding bearing assembly.
