The Bomag 05428042 Inner Ring is a genuine OEM component designed for Bomag BT-series tampers, including the BT 50, BT 55, BT 60, BT 60/4, BT 60 G, BT 60 e, BT 50 Typ2, BT 65, BT 65/4, BT 70, BT 75, BT 80 D, and BT 80 D - Torso. Sourced directly from Bomag, this inner ring matches the original specification exactly, ensuring a direct drop-in fit with no guesswork on compatibility. If your tamper is showing signs of vibration irregularities or excessive wear in the bearing assembly, replacing this component with part number 05428042 restores the machine to proper operating condition.
Key Features
- Genuine OEM Tolerancing — manufactured to Bomag's original dimensional specifications, delivering the precise bore-to-race fit that bearing performance depends on
- Direct Drop-In Replacement — engineered to install into the same bearing seat as the original, with no machining or adaptation needed
- Broad BT-Series Coverage — fits the full Bomag BT tamper lineup, including BT 50, BT 55, BT 60, BT 65, BT 75, and BT 80 D models
- Sustained Compaction Output — a correctly seated inner ring keeps the bearing assembly running true, maintaining the consistent impact force that tampers rely on for effective trench and backfill compaction
- Verified OEM Sourcing — supplied as a genuine Bomag part, so fitment accuracy for part number 05428042 is confirmed against Bomag's own catalog
The inner ring is the load-bearing core of a rolling-element bearing assembly, providing the hardened raceway surface that rolling elements travel against as the shaft rotates. In a tamper, the bearing assembly absorbs the high-frequency impact forces generated during compaction cycles, and the inner ring must maintain its geometry under that repeated stress. When the inner ring wears, develops pitting, or loses its fit on the shaft, the bearing loses its ability to transfer force cleanly — leading to increased vibration, audible noise, accelerated wear on surrounding components, and ultimately a loss of compaction performance.
