Bomag 08530509 Spring Washer

The Bomag 08530509 Spring Washer is a genuine OEM fastening component designed for an extensive range of Bomag equipment, including BW single drum rollers, tandem rollers, walk-behind and light rollers, pneumatic tyred rollers, BC refuse and landfill compactors, BC soil compactors, MPH and RS recycler/stabilizers, and BW trench compactors. As a direct OEM replacement sourced from Bomag, this spring washer matches the original part in material grade, load rating, and dimensional tolerancing — ensuring it seats and performs exactly as the factory intended. Compatible models include the BW 213 D-4, BW 174 AP-4, BW 154 AD-2, BW 120 AD, BW 24 R, BC 601 RB, BC 462 EB, MPH 122, and many others across the full Bomag lineup.

Key Features

• Genuine OEM Material Grade — manufactured to Bomag's original spring-steel specification, delivering the correct clamp load and deflection range for this application across a wide variety of assemblies
• Broad Cross-Fleet Compatibility — fits BW single drum rollers, tandem rollers, walk-behind and light rollers, pneumatic tyred rollers, BW trench compactors, BC refuse/landfill and soil compactors, and MPH/RS recycler/stabilizers, including models such as the BW 226 DH-4, BW 161 AD-4, BW 75 ADL, BC 670 RB, BC 462 EB, MPH 125, and RS 650
• Drop-In Replacement — matches the original part number 08530509 in dimensions and seating profile, so this spring washer installs directly without reworking mating fasteners or hardware
• Fastener Joint Integrity — a properly functioning spring washer maintains preload under vibration, preventing fasteners from backing out during operation; a worn or missing washer can lead to loosened assemblies and accelerated wear on surrounding components
• Verified OEM Sourcing — supplied as an authentic Bomag part, ensuring the correct hardness, surface treatment, and spring characteristics are present — qualities that determine how well the washer holds tension over its service life

A spring washer is a hardened, split or wave-formed ring placed under a fastener to maintain tension in a bolted joint. As the machine operates and vibrations pass through the frame, drivetrain, and drum assemblies, fasteners naturally experience micro-movement that can cause them to loosen over time. The spring washer's built-in deflection creates a continuous clamping force that resists this loosening effect. When a spring washer flattens, fractures, or is omitted entirely, the bolted connection loses preload — which can result in fastener back-out, component misalignment, or structural damage to the surrounding assembly.
