The Bomag 05939177 Safety Washer is a genuine OEM component designed for Bomag BPR-series reversible vibratory plates, including the BPR 45/55 D, BPR 55/65 D, BPR 65/70 D, BPR 70/70 D, and BPR 100/80 D. Sourced directly from Bomag, this safety washer matches the exact material grade, diameter, and locking profile of the original part. It installs as a direct replacement with no modification to fastener hardware or surrounding components. If you're servicing any of the covered BPR reversible vibratory plate models, part number 05939177 is the correct OEM specification washer for the application.
Key Features
- Genuine OEM Locking Security — Manufactured to Bomag's exact material and geometry specifications, ensuring the washer delivers the same clamping and locking performance as the original hardware.
- Direct Drop-In Replacement — Matches the original hole diameter, outer profile, and thickness, so this safety washer seats correctly against mating fasteners without rework.
- Broad BPR Series Coverage — Fits the BPR 45/55 D, BPR 55/65 D, BPR 65/70 D, BPR 70/70 D, and BPR 100/80 D reversible vibratory plates, covering a wide range of the BPR diesel lineup.
- Fastener Integrity Under Vibration — Reversible vibratory plates generate continuous high-frequency vibration; a correctly installed safety washer prevents fastener back-off that can lead to component loosening or structural failure.
- Critical Safety Function — Fastener retention hardware on compaction equipment is a safety-critical item; using the correct OEM-spec safety washer helps maintain the structural integrity of the assembly it secures.
A safety washer is a locking fastener component that prevents nuts or bolts from loosening under vibration, shock loads, or dynamic stress. On reversible vibratory plates like the BPR series, where the compaction mechanism generates sustained high-frequency oscillation, fastener hardware is under constant movement forces that can cause standard washers to back off over time. The safety washer engages the mating surface through its locking profile, maintaining clamp load and keeping the fastened joint secure through the machine's operating cycle. When this component is worn, missing, or substituted with an incorrect washer, fasteners can gradually loosen, putting both equipment performance and operator safety at risk.
