The Bomag 05711171 Angular Ball Bearing is a genuine OEM component designed for BW 138 AD and BW 135 AD tandem rollers. Sourced directly from Bomag, this angular ball bearing delivers the precise dimensional tolerances and load ratings required to keep these machines running at spec. It is a direct replacement for the original bearing, confirmed to fit BW 138 AD and BW 135 AD tandem rollers without modification.
Key Features
- Genuine OEM Angular Contact Tolerancing — manufactured to Bomag's exact radial and axial load specifications for this bearing position, ensuring correct contact angle and load distribution
- Direct Drop-In Replacement — matches the original bearing's dimensions and mounting interface exactly, fitting the BW 138 AD and BW 135 AD tandem rollers as intended
- Confirmed Tandem Roller Fitment — verified for Bomag BW 138 AD and BW 135 AD tandem rollers, so you can order with confidence
- Sustained Load Capacity — angular ball bearings support combined radial and axial forces; a worn or failed bearing causes vibration, uneven drum rotation, and accelerated wear on surrounding components
- Genuine Bomag Part — backed by Bomag's OEM supply chain under part number 05711171, with no substitution risk on materials or geometry
An angular ball bearing is engineered to handle loads applied at an angle — both radial (perpendicular to the shaft) and axial (along the shaft) forces simultaneously. In tandem rollers like the BW 138 AD and BW 135 AD, these bearings support rotating drum and drive components where combined loading is constant. When an angular ball bearing wears or fails, it can produce audible noise, generate heat, and allow shaft play that degrades compaction performance and puts stress on adjacent drivetrain components. Replacing a worn bearing promptly with the correct OEM part restores proper shaft alignment and smooth, efficient power transfer.
