Bomag 05939121 Hinge

The Bomag 05939121 Hinge is a genuine OEM replacement built for a wide range of Bomag equipment, including tandem rollers such as the BW 138 AD and BW 120 AD-4, single drum rollers including the BW 124 DH-4, refuse and landfill compactors across the BC 570 RB through BC 1172 RB-4 series, soil compactors including the BC 772 EB-2 and BC 772 EB-4, the BM2000/50 cold milling machine, the BMP 851 trench compactor, MPH-series recycler/stabilizers, and the BPH 80/65 S reversible vibratory plate. Sourced directly from Bomag, this hinge matches the original part in dimensions, material grade, and mounting configuration — no guesswork on compatibility. Using a genuine OEM component ensures the panel, door, or access cover it supports operates exactly as designed, maintaining safe and reliable access to service areas across all covered machine types.

Key Features

• Genuine OEM Construction — manufactured to Bomag's original material and dimensional specifications, ensuring the hinge delivers the correct pivot load rating and swing range for each covered application
• Broad Multi-Machine Coverage — a single part number fitting tandem rollers (including BW 100 AC-3 through BW 138 AD), BC-series refuse/landfill compactors, BC-series soil compactors, the BM2000/50 cold milling machine, the BMP 851 trench compactor, MPH-series recycler/stabilizers, and the BPH 80/65 S reversible vibratory plate
• Drop-In Replacement — mounts directly to the original hinge points using stock fastener locations, so reinstallation is straightforward with standard tooling
• Preserves Access Panel Integrity — a worn or broken hinge causes covers and doors to sit out of alignment, allowing dust, debris, and moisture into service compartments; this replacement restores proper seating and closure
• Exact Part Number Match — order with confidence using Bomag part number 05939121, the same number referenced in Bomag service documentation for all listed machine variants

A hinge on heavy construction equipment does more than simply allow a panel or door to open and close — it holds access covers, engine enclosures, and service doors in precise alignment under constant vibration and load cycles. When a hinge wears, bends, or fractures, covers can fail to latch securely, exposing critical components to contamination and increasing the risk of damage during operation. Replacing a failed hinge with a correctly rated OEM component restores the structural integrity of the panel assembly and ensures service access remains safe and repeatable across the machine's working life.
