The Bomag 05722225 Piston Ring Set is a genuine OEM component designed for the BP 20/48 D and BP 23/48 D vibratory plates, the BPR 30/38 D reversible vibratory plate, and the BW 71 E walk-behind roller. Sourced directly from Bomag, this piston ring set meets the exact specifications of the original equipment, ensuring proper sealing and compression in the engine. This set is a direct-fit replacement for all covered models, with no adaptation needed to match original bore dimensions and ring profiles.
Key Features
- OEM Compression Sealing — manufactured to Bomag's original ring geometry and material spec, delivering the same cylinder-wall sealing performance as the rings your machine left the factory with
- Direct Engine Fit — engineered to match the original bore diameter and groove dimensions, dropping into place without machining or modification
- Broad Model Coverage — fits BP 20/48 D and BP 23/48 D vibratory plates, the BPR 30/38 D reversible vibratory plate, and the BW 71 E walk-behind roller; verify part number 05722225 against your machine's serial plate before ordering
- Restored Engine Power — worn or broken piston rings allow combustion gases to bypass the piston, causing loss of compression, increased oil consumption, and sluggish compaction output; a fresh set restores proper cylinder pressure and full engine performance
- Complete Set — supplied as a full piston ring set so all rings are replaced together, preventing mismatched wear between new and old rings
Piston rings form a dynamic seal between the piston and the cylinder wall, keeping combustion pressure above the piston where it generates power while preventing engine oil from entering the combustion chamber. In compact compaction equipment like vibratory plates and walk-behind rollers, these engines run under sustained load in dusty, demanding site conditions, which accelerates ring wear over time. When piston rings wear thin or break, compression drops, oil burns off rapidly, and the engine loses the output needed to deliver consistent compaction force — making timely replacement with a correct-fitting set essential to keeping the machine productive.
