The Bomag 05585781 Brake Disc is a genuine OEM component designed for BW 172 D-2 and BW 142 D-2 single drum rollers. Sourced directly from Bomag, this brake disc matches the original manufacturer's specifications for material grade, friction surface geometry, and mounting dimensions — ensuring a correct fit to the braking assembly without guesswork. This is the same part installed during original production, making it the straightforward choice for a dependable brake system restoration on either machine.
Key Features
- OEM Friction Surface Integrity — Manufactured to Bomag's original material and surface specifications, delivering consistent braking force and wear characteristics expected from the factory-sourced disc.
- Direct Mounting Compatibility — Engineered to match the exact bolt pattern, disc diameter, and hub interface of the BW 172 D-2 and BW 142 D-2 braking assemblies, allowing straightforward installation without modification.
- Confirmed Fitment — Verified for Bomag BW 172 D-2 and BW 142 D-2 single drum rollers; part number 05585781 is the correct OEM reference for these machines.
- Restored Stopping Power — A worn or glazed brake disc reduces braking effectiveness on a single drum roller operating on grades and slopes; replacing with a fresh OEM disc restores full, predictable braking response.
- Braking System Safety — The brake disc is a safety-critical component; using a genuine OEM disc ensures the braking system performs within Bomag's designed load and heat-dissipation tolerances for single drum roller operation.
The brake disc is a core friction component within the machine's braking system, working in contact with brake pads or shoes to convert rotational energy into heat and bring the roller to a controlled stop. On single drum rollers like the BW 172 D-2 and BW 142 D-2, reliable braking is essential when working on uneven terrain or compacted slopes where machine control is critical. When the disc wears thin, warps from heat cycling, or develops surface cracks, braking distances increase and operator control is compromised — making timely replacement an important part of keeping the machine safe and in service.
