Wacker Neuson 5000109419 Needle Bearing

The Wacker Neuson is a genuine OEM Needle Bearing designed for the EH 9 and EHB 11 series electric breakers and demolition hammers. As a direct OEM component, it is manufactured to the same specification as the part it replaces, ensuring correct dimensional tolerancing and load capacity for the rotary and percussion mechanisms found in these tools. This bearing is confirmed compatible across a wide range of EH 9 and EHB 11 variants, including 115V and 230V models in both standard and multi-function BLM configurations. Keep your electric breakers performing at full capacity by replacing worn bearings with the correct OEM-sourced part.

Key Features

• OEM Needle Bearing Tolerancing — Manufactured to exact radial load and dimensional specs required by the EH 9 and EHB 11 breaker mechanisms, ensuring consistent rolling element contact and bore fit.
• Drop-In Installation — Matches the original bearing position and seat geometry, allowing straightforward replacement within the tool's internal drive assembly without modification.
• Broad EH / EHB Series Coverage — Compatible with EH 9 BL, EH 9 BLM, EHB 11 BL, EHB 11 BLM, and EHB 11 BLS variants across 115V and 230V configurations.
• Sustained Impact Performance — A correctly seated needle bearing maintains smooth rotation under the repeated high-frequency impact loads of demolition work; a worn bearing causes vibration, heat buildup, and accelerated internal wear.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this component carries full OEM provenance — not a generic substitute — so you can trust the part matches what was installed at the factory.

A needle bearing is a compact rolling-element bearing that uses thin cylindrical rollers to support radial loads within a small cross-sectional space. In electric breakers and demolition hammers like the EH 9 and EHB 11, needle bearings support the rotating and reciprocating shafts that drive the tool's percussion action, allowing those components to spin or cycle freely under heavy load with minimal friction. When a needle bearing wears or fails, the result is increased play in the drivetrain, excessive heat, audible rattling, and ultimately damage to surrounding components — making timely replacement critical to keeping the tool functional and safe.
