The Bomag 92021214 Inner Ring is a genuine OEM component designed for BW 184 AD-2 AM, BW 190 AD-4 AM, BW 203 AD-4 AM, and BW 203 AD-4 AM EU-Flex tandem rollers. Sourced directly from Bomag, this inner ring carries the same tolerancing and material specification as the original production part. Correct fitment is confirmed across all four tandem roller variants listed, so you can order with confidence knowing this component drops into place without adaptation.
Key Features
- Genuine OEM Tolerancing — manufactured to Bomag's original dimensional specification, ensuring the bearing interface seats correctly and maintains the load-path integrity of the drum or drivetrain assembly
- Direct OEM Replacement — matches the original inner ring geometry, bore diameter, and surface finish for a clean, straightforward swap during scheduled service or repair
- Confirmed Tandem Roller Fitment — compatible with BW 184 AD-2 AM, BW 190 AD-4 AM, BW 203 AD-4 AM, and BW 203 AD-4 AM EU-Flex tandem rollers
- Sustained Rotation Accuracy — a properly dimensioned inner ring keeps bearing play within spec, preventing vibration, uneven drum wear, and premature bearing failure on high-cycle compaction equipment
- Authentic Bomag Part Number — part number 92021214 is the exact Bomag catalog reference, eliminating cross-reference guesswork when sourcing through DHS Equipment
The inner ring is the internal race of a rolling-element bearing, providing the hardened, precision-ground surface that the rolling elements — balls or rollers — travel along as the shaft rotates. It transmits rotational load between the shaft and the bearing assembly, and its dimensional accuracy directly controls bearing clearance and overall assembly life. When an inner ring wears, develops surface fatigue, or loses its roundness, the result is increased vibration, bearing noise, heat buildup, and eventually bearing seizure — all of which can sideline a tandem roller and accelerate wear on surrounding components. Replacing a worn inner ring with a genuine Bomag part restores the bearing to its original running specification and protects the investment in the wider drivetrain or drum assembly.
