Key Features
- Genuine OEM Dimensional Accuracy — manufactured to the precise tolerances required for correct bearing assembly seating and load distribution in Bomag tandem rollers
- Drop-In Replacement — this inner ring installs directly into the original bearing housing with no reworking or adaptation of mating components
- Broad Tandem Roller Coverage — fits the BW 144 AD-2, BW 154 AD-2, BW 170 AD, BW 174 AC AM, BW 174 AD AM, BW 184 AD, BW 184 AD-2 AM, BW 190 AD-4 AM, BW 203 AD-4 AM, and BW 203 AD-4 AM EU-Flex
- Sustained Drum Performance — a correctly fitted inner ring maintains proper bearing preload, keeping drum rotation smooth and preventing premature wear on surrounding components
- Verified Part Number Match — ordering by Bomag part number 87240235 eliminates the guesswork of cross-referencing, ensuring you receive the right component for your machine
The inner ring is a core element of a rolling-element bearing assembly, forming the inner raceway that rotates with the shaft while the rolling elements travel between it and the outer ring. In a tandem roller, bearings supported by this inner ring carry the dynamic loads generated during drum rotation and machine travel — keeping the drum aligned and running true. When an inner ring wears, becomes pitted, or loses its dimensional integrity, it causes uneven load transfer, increased vibration, accelerated bearing failure, and ultimately compromised compaction performance across the full working width of the roller.
