Bomag 05231130 Taper Roller Bearing

The Bomag 05231130 Taper Roller Bearing is a genuine OEM component designed for Bomag BW-series single drum rollers and MPH/RS recyclers and stabilizers. Sourced directly from Bomag, this taper roller bearing matches the original specification for the precise dimensional tolerances and load ratings required in heavy compaction and stabilization equipment. This bearing is confirmed to fit an extensive range of machines spanning the BW 124, BW 145, BW 177, BW 211, BW 212, BW 213, BW 214, BW 216, BW 219, BW 226, and BW 332 single drum roller lines, as well as select MPH-series and RS-series recycler/stabilizer models including the MPH 121, MPH 122, MPH 125, MPH 600, RS 460, and RS 650. When ordering, confirm your model and configuration using part number 05231130 to ensure an exact match.

Key Features

• Genuine OEM Load Rating — manufactured to Bomag's original radial and axial load specifications, maintaining the bearing's correct capacity for heavy drum and drivetrain forces on single drum rollers
• Drop-In Dimensional Match — the taper roller bearing installs directly into the original housing without modification, preserving correct preload and bearing seat integrity
• Broad BW-Series and Recycler Coverage — fits BW 124, BW 145, BW 177, BW 211, BW 212, BW 213, BW 214, BW 216, BW 219, BW 226, and BW 332 single drum rollers, plus MPH 121, MPH 122, MPH 125, MPH 600, RS 460, RS 650, and BSF 2500 recyclers/stabilizers
• Sustained Compaction Performance — a correctly seated taper roller bearing supports smooth drum rotation and proper drivetrain alignment; a worn bearing causes vibration, uneven drum loading, and accelerated wear on surrounding components

A taper roller bearing is designed to handle both radial loads (perpendicular to the shaft) and axial thrust loads (along the shaft) simultaneously, making it well suited for the high-force, multi-directional loading conditions found in compaction equipment. In a single drum roller, these bearings are commonly used in drum support assemblies and drivetrain shafts, where they maintain precise alignment under continuous vibration and heavy compaction loads. When a taper roller bearing wears or loses its preload, operators typically notice increased noise, heat buildup, shaft play, or irregular drum behavior — all signs that replacement with a correct OEM bearing is needed to restore proper machine operation.
