The Bomag 05586151 Reducing Bush is a genuine OEM component designed for Bomag BW-series single drum rollers and MPH-series recycler/stabilizers, including the BW 213 D-3, BW 219 DH-3, BW 219 PDH-3, BW 219 D-4, BW 219 DH-4, BW 219 PDH-4, BW 225, BW 225 D-3, BW 226 DH-4, BW 226 PDH-4, BW 226 DH-4i, BW 332, MPH 121, and MPH 122 and MPH 122-2. Sourced directly from Bomag, this reducing bush matches the original specification for a drop-in installation with no adaptation needed. Confirm your model and serial number against the fitment list before ordering to ensure an exact match for your machine.
Key Features
- Genuine OEM Dimensional Accuracy — manufactured to Bomag's original bore and shoulder tolerances, ensuring the bush seats correctly and holds its rated load without fretting or creep
- Direct Replacement Fit — engineered to the same interface dimensions as the original, so this reducing bush installs into the existing housing without reworking the bore or mating components
- Broad Model Coverage — confirmed fitment across BW 213 D-3, BW 219, BW 225, BW 226, and BW 332 single drum rollers, as well as MPH 121, MPH 122, and MPH 122-2 recycler/stabilizers
- Sustained Load Transfer — a correctly fitted reducing bush maintains proper shaft-to-housing alignment, preventing uneven wear on adjacent bearings and hydraulic or drivetrain components that depend on concentricity
- OEM Part Number Confidence — ordering by part number 05586151 ensures you receive the exact Bomag-specified component, eliminating guesswork when sourcing a replacement
A reducing bush is a precision sleeve that bridges the gap between two different diameter bores or shafts, allowing components with mismatched sizes to seat and rotate concentrically within an assembly. In heavy compaction equipment and recycler/stabilizer machines, this bush maintains the correct alignment between rotating or reciprocating shafts and their housings, ensuring even load distribution and preventing metal-to-metal contact that would accelerate wear. When a reducing bush wears, becomes corroded, or loses its press fit, the resulting play causes vibration, premature bearing failure, and degraded machine performance — making timely replacement essential to keeping the drivetrain and associated systems running as intended.
