The Bomag 31780802 Roller Bearing is a genuine OEM component designed for BW 177-series and BW 213-series single drum rollers, BW 184 AD and BW 180 AD tandem rollers, and the C 850 C single drum roller. Sourced directly from Bomag, this roller bearing matches the original specification for a drop-in installation with no guesswork on compatibility. Confirmed fitment spans a broad range of Bomag compaction equipment, giving fleet operators and service technicians confidence that part number 31780802 is the correct replacement every time.
Key Features
- Genuine OEM Precision — manufactured to Bomag's original tolerancing and load-rating specifications, ensuring the bearing handles the radial and axial forces your machine generates under compaction loads
- Direct Replacement Fit — matches the original bearing seat dimensions and retention style for straightforward installation in the same housing as the worn part
- Broad Bomag Coverage — fits BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, and BW 213 D-3 single drum rollers, BW 213 PDH-3 single drum rollers, BW 184 AD and BW 180 AD tandem rollers, and the C 850 C single drum roller
- Sustained Load Capacity — a correctly seated roller bearing keeps rotating assemblies aligned and running smoothly; a worn or seized bearing leads to increased heat, vibration, and accelerated damage to surrounding components
- Verified Bomag Part Number — order with confidence using part number 31780802, the exact Bomag catalog reference for this application
A roller bearing supports rotating shafts and assemblies by using cylindrical rolling elements to carry radial loads with minimal friction. In a compaction roller, these bearings are critical to keeping drum drives, vibration shafts, and other rotating components running true under the heavy cyclic loads of daily compaction work. When a roller bearing wears, it typically produces audible noise, increased vibration outside normal operating parameters, and heat buildup — symptoms that, left unaddressed, can progress to shaft damage or sudden component failure and unplanned downtime.
