The Bomag 31780504 Ball Bearing is a genuine OEM component designed for a wide range of Bomag tandem rollers, single drum rollers, and pneumatic tyred rollers. Sourced directly from Bomag, this ball bearing meets the exact dimensional and load tolerances specified for these machines, ensuring a correct installation with no guesswork. Confirmed fitment includes the BW 184 AD, BW 184 AD-2, BW 184 AD-2 AM, BW 180 AD, BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 213 D-3, BW 213 DH-3 USA, BW 213 PDH-3, BW 213 PDH-3 USA, BW 211 D-5 SL, BW 213 D-5 SL, BW 24 R, C 560 B, and C 850 C rollers. Replacing a worn bearing promptly keeps the drivetrain and rotating assemblies operating smoothly and protects surrounding components from accelerated wear.
Key Features
- Genuine OEM Tolerancing — manufactured to Bomag's exact radial clearance and load-rating specifications, so this ball bearing seats correctly and handles both radial and axial forces as intended
- Direct Drop-In Replacement — matches the original bearing's bore, outer diameter, and width for a straightforward swap without machining or shimming
- Broad Roller Coverage — fits Bomag BW 177, BW 180, BW 184, BW 211, BW 213, BW 24 R single drum, tandem, and pneumatic tyred rollers, as well as C 560 B and C 850 C rollers
- Sustained Rotation Efficiency — a properly functioning ball bearing minimizes friction in rotating assemblies; a worn or failed bearing causes vibration, heat buildup, and damage to shafts and housings
- Verified Part Number Integrity — order with confidence using Bomag part number 31780504 to confirm you are receiving the correct bearing for your machine
A ball bearing supports rotating shafts and hubs by reducing friction between moving surfaces through a set of precision steel balls running between inner and outer races. In compaction rollers, ball bearings are found in drivetrain assemblies, vibration systems, and wheel hubs, where they carry both rotational loads and side forces generated during operation. When a ball bearing wears, develops pitting, or loses its grease retention, the resulting friction and play lead to excessive heat, noise, and eventual failure of the shaft or surrounding housing — making timely replacement essential to keeping the machine productive.
