The Bomag 05428122 Inner Ring is a genuine OEM component designed for Bomag BPR-series reversible vibratory plates and BP-series vibratory plates, including the BPR 25/40, BPR 35/42 D, BPR 35/60 D, BPR 40/60 D, BP 10/35, BP 12/40, BP 20/50, and BP 25/50, among others. Sourced directly from Bomag, this inner ring carries the same part number 05428122 used in the original assembly, so there is no guesswork on compatibility. It drops into place as a direct replacement, restoring the original fit and function without rework or adaptation. For operators and service technicians running Bomag vibratory plates, ordering the correct OEM inner ring the first time keeps the repair straightforward and the machine back in service quickly.
Key Features
- Genuine OEM Dimensional Accuracy — manufactured to the same bore tolerances and surface finish as the original, ensuring correct load distribution within the bearing assembly on your vibratory plate
- Direct-Fit Replacement — matches part number 05428122 exactly, seating into the bearing housing just as the factory-installed component did with no machining or shimming needed
- Broad Plate Compatibility — fits a wide range of Bomag reversible vibratory plates including the BPR 25/40, BPR 25/50, BPR 35/42, BPR 35/60, BPR 40/60 D, and BPR 35/60 e, as well as forward vibratory plates including the BP 10/35, BP 12/40, BP 12/50 A, BP 20/50, BP 25/50, and their diesel variants
- Sustained Compaction Performance — a correctly fitted inner ring maintains proper eccentric shaft rotation, preserving the vibratory force and compaction output the plate was engineered to deliver; a worn or out-of-spec ring accelerates bearing failure and degrades plate performance
- OEM Part Number Traceability — the Bomag part number 05428122 is verifiable against Bomag's own parts catalog, giving you confidence that this is the correct component for your machine before the wrench ever touches it
The inner ring is the interior race of a rolling-element bearing, providing the precision surface that the rolling elements — balls or rollers — travel against as the shaft rotates. In a vibratory plate compactor, bearings support the eccentric shaft that generates the vibration force transmitted to the ground, and the inner ring must maintain strict dimensional tolerances to carry that dynamic load without generating heat or play. When an inner ring wears, develops scoring, or loses its roundness, the bearing loses its ability to support the shaft cleanly, leading to increased vibration in the wrong places, audible noise, and eventual bearing seizure that can take the entire eccentric assembly out of service.
