The Wacker Neuson is a genuine OEM Inclined Ball Bearing designed for the EH 100 series electric demolition breakers, including 28x152, 28x160, and 32x160 chisel configurations. As a factory-sourced component, the is manufactured to the exact tolerances required to maintain proper angular load transfer within the breaker's internal drive mechanism. This genuine OEM part is the correct specification for EH 100/230 and EH 100/240 variants sold in the US and international markets, giving you confidence in fitment before the part ever arrives on site.
Key Features
- Angular Load Precision: — Engineered to the exact contact-angle specification required for the EH 100 breaker's reciprocating drive, maintaining consistent load distribution under high-impact cycling.
- Genuine OEM Sourcing: — Factory-supplied by Wacker Neuson, ensuring the bearing grade, race geometry, and ball complement match the original design — not an approximation of it.
- Broad EH 100 Coverage: — Compatible across EH 100/230 and EH 100/240 electric breakers in 28x152, 28x160, and 32x160 hex configurations, including US and BR market variants.
- Direct Internal Fit: — Seats into the same bearing pocket as the original, requiring no shimming, machining, or adaptation during reassembly.
- Sustained Impact Performance: — A worn or failed inclined ball bearing causes irregular piston travel, increased vibration, and accelerated wear on surrounding drive components — replacing it restores consistent blow energy and smooth operation.
- Electrical Safety Compliance: — Using the correct OEM bearing in an electric breaker preserves the mechanical alignment that protects internal electrical components from stress-induced damage during operation.
The inclined ball bearing in an electric demolition breaker like the EH 100 is a precision load-carrying component positioned within the rotary-to-reciprocating drive assembly. Its angled contact geometry allows it to simultaneously handle axial and radial forces generated during high-frequency hammer strikes, keeping the piston and drive mechanism aligned under constant impact load. When this bearing wears or fails, blow energy drops noticeably, vibration increases, and continued operation can damage the crank mechanism, leading to a more extensive and costly repair.
