Wacker Neuson 5000109418 Inner Race Bearing

The Wacker Neuson Inner Race Bearing is a genuine OEM component designed for the EH 9 and EHB 11 series electric breakers and demolition hammers. As a factory-sourced part, the meets the original dimensional and material specifications required for proper drivetrain alignment and load handling within these machines. This bearing fits a broad range of EH 9 and EHB 11 variants across 115V and 230V configurations, including BL, BLM, and BLS chuck-style models. Whether you are servicing a rotary hammer or an SDS-max chiseling tool, this is the correct OEM replacement to restore the machine to full working condition.

Key Features

• OEM-Grade Bearing Tolerancing — Manufactured to the original radial and axial tolerance specifications, ensuring smooth rotation and correct load distribution inside the hammer mechanism.
• Drop-In Compatibility — Engineered to seat directly into the original bearing housing without modification, preserving correct shaft alignment and tool-holder concentricity.
• Broad EH 9 and EHB 11 Fitment — Covers BL, BLM, and BLS variants across both 115V and 230V models, making this a single-part solution for a wide range of Wacker Neuson electric breaker and hammer configurations.
• Sustained Impact Performance — A correctly fitted inner race bearing maintains the rotational integrity of the hammer's drive assembly, sustaining consistent blow energy and preventing premature wear on surrounding components.
• Structural Integrity Under Sustained Load — Demolition tools subject bearings to intense cyclical stress; using a genuine OEM inner race ensures the bearing retains its rated load capacity across extended service intervals.

The inner race bearing is a core component of the rotating drive assembly in an electric breaker or rotary hammer. It sits between the rotating shaft and the outer bearing ring, allowing the shaft to spin freely while transferring radial and axial loads generated by the hammering action. When the inner race becomes worn, pitted, or cracked, the result is increased vibration, audible rumbling, and loss of strike efficiency — eventually leading to shaft misalignment or failure of the surrounding drivetrain components. Replacing the 5000109418 at the first sign of wear is the most direct way to protect the integrity of the full hammer assembly.
