The Wacker Neuson is a genuine OEM Snap Ring A28 designed for the EH 9 BLM and EHB 11 BLM series electric breakers and hammers. As a direct OEM replacement sourced through Wacker Neuson's authorized parts program, this snap ring is manufactured to the exact dimensional and material specifications of the original component. It fits across a wide range of 115V and 230V variants in both the EH 9 BLM and EHB 11 BLM families, including WMI and Loxam configurations. Confirming part number against your machine's serial number before ordering is always the best practice for snap ring replacements.
Key Features
- Exact A28 Diameter Specification — Manufactured to the precise A28 groove diameter required by Wacker Neuson's internal hammer mechanism, ensuring correct seating and retention without modification.
- Genuine OEM Component — Sourced directly from Wacker Neuson, this snap ring meets the same hardness and spring-temper standards as the part originally installed on the production line.
- Broad EH / EHB Series Compatibility — Fits EH 9 BLM and EHB 11 BLM electric breakers and hammers across multiple voltage configurations (115V and 230V), including WMI and Loxam variants.
- Retains Critical Internal Components — A correctly seated snap ring holds drive and hammer assembly components in their proper axial positions; a worn or missing ring allows internal parts to migrate, causing rapid internal wear.
- Drop-In Service Part — Matches the original installation point directly, making it suitable for standard field or shop servicing without specialist tooling beyond a snap ring applicator.
A snap ring is a small but essential retaining fastener used inside rotary and percussion tools to lock shafts, bearings, or internal drive components in their correct axial position within the housing. In electric breakers and hammers like the EH 9 BLM and EHB 11 BLM, the snap ring prevents critical internal parts from shifting under the repeated high-impact loads generated during chiseling and drilling operations. When a snap ring becomes worn, deformed, or fractured, internal components lose their positional constraint, leading to accelerated wear, loss of striking energy, and potential damage to surrounding assemblies.
