The Wacker Neuson Collar Ring Vibration Dampening Bolt Sleeve is a genuine OEM component designed for the EH 9, EHB 10, and EHB 11 series electric breakers and demolition hammers. Sourced directly from Wacker Neuson, this part matches the original specification installed at the factory, ensuring a correct fit within the hammer's vibration isolation system. It is compatible across a wide range of voltage configurations including 110V, 115V, 230V, 240V, and multi-voltage variants, covering both standard and specialty market builds. When you need to restore proper vibration damping to your electric breaker, the is the part to reach for.
Key Features
- Genuine OEM Vibration Isolation Material: — Manufactured to Wacker Neuson's original damping compound and dimensional spec, so the sleeve absorbs bolt-transmitted shock the same way the original did from day one.
- Direct Bolt-Sleeve Replacement: — Seats into the same collar position as the factory part, requiring no modification to the hammer housing or bolt hardware.
- Broad EH / EHB Series Coverage: — A single part number covers EH 9 BL, EHB 10, and EHB 11 BL variants across 110V, 115V, 230V, and 240V configurations, making it a reliable stock item for fleets running multiple hammer models.
- Protects Structural Components from Shock Transfer: — A healthy dampening sleeve isolates the percussion mechanism from the housing bolts; a cracked or hardened sleeve allows metal-to-metal contact that accelerates wear on surrounding castings and fasteners.
- Reduces Operator-Felt Vibration: — Correctly functioning vibration damping hardware helps maintain the hammer's HAV (hand-arm vibration) characteristics within its designed operating range, keeping conditions safe and comfortable for the operator during extended breaking work.
The Collar Ring Vibration Dampening Bolt Sleeve sits between the breaker's internal bolt hardware and the surrounding housing collar, acting as a buffer that absorbs and dissipates the high-frequency shock generated by the percussion mechanism. By isolating this bolt-transmitted energy, it prevents vibration from feeding directly into the tool housing and handle, protecting both the machine's structural integrity and the operator. When the sleeve hardens, cracks, or degrades, shock loads transfer unchecked into the housing, leading to fastener loosening, premature wear on adjacent components, and increased handle vibration felt by the operator.
