The Bomag 46280109 Bearing Housing is a genuine OEM component designed for BW 80, BW 90, and BW 100 series tandem rollers, as well as the BW 900-50 walk-behind/light roller. Sourced directly from Bomag, this bearing housing delivers the exact dimensional tolerances and material specification required to properly locate and support the bearing assembly in the drum drive system. It is a confirmed fit for the BW 80 AD-2, BW 90 AC-2, BW 90 AD-2, BW 80 AD-5, BW 90 AD-5, BW 90 AC-5, BW 90 SC-5, BW 90 SL-5, BW 90 SL-5 CC, BW 100 SCC-5, BW 100 SC-5, BW 100 ADM-5, BW 100 ACM-5, BW 100 SLM-5, and BW 900-50. As a genuine OEM part, it installs directly into position without rework or adaptation, restoring the housing to its original service condition.
Key Features
- Genuine OEM Dimensional Accuracy — manufactured to Bomag's original bore tolerances and seating geometry, ensuring the bearing is held at the correct alignment and load angle for the drum drive
- Direct OEM Replacement — part number 46280109 matches the original housing specification, dropping straight into the existing mounting points on compatible BW-series tandem and light rollers
- Broad BW-Series Coverage — confirmed fitment across BW 80, BW 90, and BW 100 series tandem rollers including the BW 90 SL-5 CC and BW 100 SLM-5, plus the BW 900-50 walk-behind/light roller
- Sustained Drum Drive Integrity — a correctly fitted housing keeps the bearing correctly positioned under vibratory and rotational loads; a worn or cracked housing allows bearing movement that accelerates wear across the entire drum drive assembly
- OEM Part Assurance — sold by DHS Equipment as a genuine Bomag part, so the specification, material grade, and finish match what left the factory originally
The bearing housing locates and retains the drum drive bearing in precise alignment within the roller's drum assembly. It transfers rotational and vibratory loads from the bearing into the surrounding structure, keeping the bearing seated correctly under the demanding operating conditions of compaction work. When the housing cracks, corrodes, or wears at the bore, the bearing loses its seating, which causes rapid bearing failure, drum misalignment, and can ultimately damage the drum shaft — making timely housing replacement essential to protecting the broader drivetrain.
