The Bomag 05276112 Spherical Plain Bearing is a genuine OEM component designed for BW 177 series single drum rollers, including BW 177 D, BW 177 DH, BW 177 PDH, BW 177 DHC, and BW 177 PDHC variants across the -3, -4, -40, and -50 generations. Sourced directly from Bomag, this bearing meets the exact engineering specifications of the original installed part. It delivers a direct, drop-in fit across the full BW 177 lineup without adaptation, making it the straightforward choice for scheduled maintenance or unplanned replacement. Confirm your model and generation against part number 05276112 before ordering to ensure correct application.
Key Features
- Genuine OEM Bearing Tolerances — manufactured to Bomag's original dimensional and load-rating specifications, ensuring the self-aligning contact surface performs as designed under compaction stress and articulation loads
- Direct OEM Replacement — engineered to seat and retain exactly as the factory-installed bearing, with correct bore, outer diameter, and spherical geometry matching the original mounting point
- Broad BW 177 Coverage — fits BW 177 D, BW 177 DH, BW 177 PDH, BW 177 DHC, BW 177 PDHC, and BW 177 D-40, BW 177 DH-40, BW 177 PDH-40, BW 177 D-50, BW 177 DH-50, and BW 177 PDH-50 single drum rollers
- Sustained Articulation Performance — a correctly functioning spherical plain bearing allows controlled angular movement at pivot and linkage points; a worn bearing introduces slop, accelerates surrounding component wear, and degrades steering and frame response on the roller
- Verified Part Number Fit — ordering by Bomag part number 05276112 ensures you receive the correct bearing for your BW 177 series machine, eliminating guesswork on interchange compatibility
A spherical plain bearing is a sliding-contact bearing that incorporates an inner ring with a convex outer surface and an outer ring with a matching concave inner surface, allowing controlled angular misalignment between connected components. On a single drum roller like the BW 177 series, these bearings are used at articulation joints, linkage pivots, and steering connections where the machine flexes and pivots under load during compaction passes. When the bearing wears, clearance builds up at the joint, causing imprecise steering response, increased vibration transfer into surrounding structures, and accelerated wear on pins, bores, and mating hardware — making timely replacement essential to keeping the machine operating accurately and safely.
