The Bomag 05903989 Cylinder Roller Bearing is a genuine OEM component designed for BC 972 RB-3, BC 972 RB-4, BC 1172 RB-3, and BC 1172 RB-4 refuse and landfill compactors. Sourced directly from Bomag, this bearing meets the original design specification for these heavy-duty machines. It installs as a direct replacement, restoring proper rotational support to the drivetrain or working assembly with no adaptation required. Confirm fitment using part number 05903989 before ordering to ensure exact compatibility with your compactor.
Key Features
- Genuine OEM Precision — manufactured to Bomag's original tolerance and load-rating specifications for cylinder roller bearings, ensuring correct radial load capacity and dimensional accuracy
- Direct Replacement Fit — engineered to drop into the same mounting position as the original bearing, preserving correct shaft alignment and housing clearances on your compactor
- Broad BC-Series Coverage — fits BC 972 RB-3, BC 972 RB-4, BC 1172 RB-3, and BC 1172 RB-4 refuse and landfill compactors, covering both the RB-3 and RB-4 generations of the BC 972 and BC 1172
- Sustained Load Handling — a properly seated cylinder roller bearing keeps rotating shafts tracking true under the extreme radial loads generated by landfill compaction cycles; a worn bearing leads to shaft deflection, accelerated housing wear, and eventual drivetrain damage
- Verified Part Number — order with confidence using Bomag part number 05903989, cross-referenced to the BC 972 and BC 1172 RB-series compactor parts catalog
A cylinder roller bearing provides radial load support for a rotating shaft, using cylindrical rolling elements arranged between inner and outer races to reduce friction and carry heavy side loads. In large refuse and landfill compactors like the BC 972 RB and BC 1172 RB, these bearings are subjected to continuous shock loading and contamination during compaction work on landfill faces. When a cylinder roller bearing wears or fails, shaft runout increases, surrounding seals and housings take on abnormal stress, and the resulting vibration can spread damage to adjacent drivetrain components — making timely replacement critical to keeping the machine working at full capacity.
