The Bomag 05570520 Safety Washer is a genuine OEM component designed for BC-series refuse and landfill compactors, including the BC 571 RB, BC 671 RB, BC 671 RS, BC 672 RB, BC 771 RB, BC 771 RS, BC 772 RB, BC 772 RS, BC 972 RB, and BC 1172 RB. Sourced directly from Bomag, this safety washer matches the exact material grade and dimensional tolerances of the original part it replaces. When secure fastener retention matters on heavy-duty compaction equipment, installing the correct OEM-specified washer keeps connections performing as intended across the full range of demanding landfill and refuse compaction cycles.
Key Features
- OEM Material Integrity — manufactured to Bomag's original hardness and dimensional spec, ensuring the washer delivers proper load distribution and fastener locking performance in high-vibration compactor environments
- Direct Bolt-On Replacement — matches the original profile and inside diameter for straightforward installation without modification, slotting directly into existing fastener assemblies
- Broad BC-Series Coverage — fits ten refuse and landfill compactor models including the BC 571 RB, BC 671 RB, BC 671 RS, BC 672 RB, BC 771 RB, BC 771 RS, BC 772 RB, BC 772 RS, BC 972 RB, and BC 1172 RB
- Fastener Security Under Load — a correctly functioning safety washer prevents fastener back-out and loosening caused by the constant vibration and shock loads generated during compaction work; a missing or worn washer risks joint failure and unplanned disassembly
- Genuine Bomag Part — supplied as genuine OEM under part number 05570520, eliminating fitment uncertainty and supporting consistent maintenance records on your compactor fleet
A safety washer is a hardened locking washer used beneath a fastener to prevent it from loosening under vibration, dynamic loading, or repeated stress cycles. On refuse and landfill compactors like the BC-series machines, which operate across rough, uneven terrain and subject their frames and assemblies to continuous shock, these washers play a critical role in keeping bolted joints intact. When a safety washer becomes deformed, corroded, or lost entirely, the fastener it secures can work loose over time, leading to component movement, accelerated wear, or fastener failure that escalates into more significant mechanical problems. Replacing worn or damaged safety washers as part of routine maintenance is a straightforward step that protects the integrity of the broader assembly.
