Bomag Angular Ball Bearing | Part 08821079

The Bomag 08821079 Angular Ball Bearing is a genuine OEM component designed for a wide range of Bomag single drum rollers, pneumatic tyred rollers, soil compactors, refuse/landfill compactors, and cold milling machines. Sourced directly from Bomag, this angular ball bearing carries the exact tolerances and load ratings specified for these machines — ensuring the bearing seats and performs exactly as the original did. Compatible models include BW 211, BW 213, BW 216, BW 219, and BW 226 series single drum rollers across multiple generations, BW 24 RH, BW 27 RH, and BW 28 RH pneumatic tyred rollers, BC 462 EB soil compactors, BC 462 RB, BC 472 RB, and BC 472 RS refuse/landfill compactors, and BM 500/15 and BM 600/15 cold milling machines.

Key Features

• OEM-Spec Angular Contact Design — manufactured to Bomag's precise angular contact geometry, supporting the combined radial and axial loads that roller and compactor drivetrains generate under sustained vibration
• Direct-Fit Replacement — matches the original bearing's dimensions, race profile, and seat diameter so this bearing installs into the housing without modification
• Broad Model Coverage — fits BW 211, BW 213, BW 216, BW 219, and BW 226 single drum rollers, BW 24 RH, BW 27 RH, and BW 28 RH pneumatic tyred rollers, BC 462 EB and BC 462/472 RB/RS compactors, and BM 500/15 and BM 600/15 cold milling machines
• Sustained Load Capacity — angular ball bearings handle the simultaneous thrust and radial forces produced during compaction cycles; a worn or failed bearing causes excessive play, heat buildup, and accelerated wear on adjacent drivetrain components
• Verified Part Number Fit — ordering by genuine Bomag part number 08821079 confirms you receive the correct bearing grade and geometry for your machine, eliminating guesswork on a critical rotating component

An angular ball bearing is designed to carry loads that act simultaneously in both the radial direction (perpendicular to the shaft) and the axial direction (along the shaft), making it well suited to the high-vibration, variable-load environment of heavy compaction equipment. Inside a roller or compactor, this bearing type is commonly found in drum drive assemblies, gearbox shafts, and wheel hubs, where it keeps rotating components aligned under the stresses of continuous operation. When an angular ball bearing wears or loses its preload, the resulting play in the shaft creates vibration, accelerated seal wear, and eventual damage to surrounding components — making timely replacement essential to keeping the drivetrain running smoothly.
