The Wacker Neuson Locking Bushing is a genuine OEM component designed for the EH 9 and EHB 11 series electric breakers and hammers, including SDS-max drilling and chiseling models available in both 115V and 230V configurations. As a factory-sourced part, the is manufactured to the exact tolerances required by Wacker Neuson for correct fit and consistent performance across compatible models. This locking bushing serves a critical retention function within the tool's internal drive assembly, making prompt replacement essential when wear or damage is detected. Confirm your model number against the fitment list before ordering to ensure compatibility with your specific machine variant.
Key Features
- Genuine OEM Tolerancing — Manufactured to Wacker Neuson's exact dimensional specifications, ensuring the bushing seats and locks correctly within the drive mechanism without play or misalignment.
- Direct Internal Fit — Engineered to drop into the existing retention point within the EH 9 and EHB 11 hammer assemblies, requiring no modification to surrounding components during installation.
- Broad EH / EHB Series Coverage — Compatible across multiple variants of the EH 9 and EHB 11 electric breaker and hammer lineup, spanning 115V and 230V models including WMI and Loxam-designated units.
- Retention Integrity Under Impact — A correctly functioning locking bushing keeps internal drive components positionally stable during repeated hammer blows; a worn or failed bushing can cause internal component migration and accelerated wear throughout the assembly.
- Safety-Relevant Retention Component — Proper bushing function helps prevent unintended movement of internal drive parts during operation, supporting safe and controlled tool performance in demolition and chiseling applications.
The locking bushing is an internal retention component that holds a shaft, pin, or drive element securely in its designed position within the hammer mechanism. In an electric breaker or rotary hammer, the repeated percussive and rotational forces place constant stress on internal retention points — the locking bushing absorbs and resists the lateral and axial forces that would otherwise allow critical components to shift during operation. When the bushing wears down or fails, internal parts can migrate out of alignment, leading to increased vibration, loss of impact efficiency, and potential damage to surrounding components.
