The Bomag 05902446 Thrust Disc is a genuine OEM replacement designed for Bomag BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, BW 27 RH-4i BC, BW 28 RH pneumatic tyred rollers, and the BW 177 PDH 5 single drum roller. Sourced directly from Bomag, this thrust disc matches the original component in every dimension and material specification, ensuring a correct installation without guesswork. Verified compatibility across the full range of supported models makes part number 05902446 a straightforward choice for fleet maintainers and service technicians keeping these machines in top condition.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original tolerances, this thrust disc delivers the same axial load control and dimensional accuracy as the factory-installed component
- Direct Drop-In Replacement — engineered to match the original mounting profile, this disc seats correctly without rework or shimming during installation
- Broad Roller Coverage — fits BW 24 RH, BW 25 RH, BW 27 RH, BW 27 RH-4i, BW 27 RH-4i BC, and BW 28 RH pneumatic tyred rollers, as well as the BW 177 PDH 5 single drum roller
- Axial Stability Restored — a worn or cracked thrust disc allows unwanted axial shaft movement, leading to accelerated bearing wear and inconsistent compaction output; replacing it promptly protects surrounding drivetrain components
- Verified Part Number — order with confidence using Bomag part number 05902446, confirmed against the original Bomag parts catalog for these machines
A thrust disc is a hardened load-bearing component positioned along a rotating shaft to control axial (end-to-end) movement and absorb thrust forces generated during operation. In pneumatic tyred and single drum rollers, it works alongside bearings to keep shaft assemblies properly aligned under the significant dynamic loads produced during compaction passes. When a thrust disc wears thin or cracks, shaft end-play increases, placing undue stress on adjacent bearings and seals — often leading to more extensive and costly repairs if left unaddressed.
