The Bomag 58610641 Pillow Block is a genuine OEM bearing housing component designed for BW 145 and BW 177 series single drum rollers. Sourced directly from Bomag, this pillow block delivers the exact dimensional tolerances and mounting geometry required for proper shaft alignment and bearing retention on these machines. This part is confirmed to fit the BW 145 D-5, BW 145 DH-5, BW 145 PDH-5, BW 177 D-5, BW 177 DH-5, BW 177 PDH-5, and BW 177BVC-5 single drum rollers. When a pillow block wears or fails, vibration, misalignment, and accelerated bearing damage follow — replacing it with the correct OEM component keeps drivetrain components running true.
Key Features
- OEM Housing Integrity — machined to Bomag's exact bore tolerances, ensuring the bearing seat holds proper alignment under the high-vibration demands of compaction equipment
- Drop-In Replacement — matches the original mounting footprint and bolt pattern, so this pillow block installs directly onto the machine without modification
- Broad BW 145 and BW 177 Coverage — fits the BW 145 D-5, BW 145 DH-5, BW 145 PDH-5, BW 177 D-5, BW 177 DH-5, BW 177 PDH-5, and BW 177BVC-5 single drum rollers
- Drivetrain Protection — a correctly seated pillow block prevents shaft deflection and premature bearing failure, protecting surrounding drivetrain components from cascading wear
- Genuine Bomag Part — supplied as authentic OEM under part number 58610641, ensuring material grade and dimensional spec match the original production component
A pillow block is a mounted bearing housing that supports a rotating shaft at a fixed point on the machine frame. It holds the bearing in correct alignment while absorbing radial and axial loads generated during drum operation and travel. When a pillow block cracks, corrodes, or wears beyond tolerance, the bearing it houses loses proper support — leading to shaft runout, increased vibration, noise, and eventual bearing seizure that can sideline the roller entirely. Replacing a worn pillow block with a genuine OEM unit restores the precise shaft geometry the drivetrain depends on.
