The Wacker Neuson is a genuine OEM Needle Bearing designed for the EH 100/240 and EH 100/230 series electric demolition breakers and hammers. As a direct OEM replacement, this bearing is manufactured to the same standards as the original component — ensuring it installs correctly and performs as intended in your machine. Fitment covers multiple EH 100 configurations including 28x152, 28x160, and 32x160 tool chuck sizes, as well as the EH 100/230 BR electric hammer variant.
Key Features
- OEM-Grade Bearing Tolerances — Produced to the same dimensional and material specifications as the factory-installed unit, maintaining the tight radial clearances that needle bearings in high-impact applications demand.
- Drop-In Fitment for EH 100 Series — Engineered to seat directly into the EH 100 breaker housing without modification, preserving correct alignment between the piston and chuck assembly.
- Broad EH 100 Compatibility — Confirmed for EH 100/240 (28x152), EH 100/230 (28x160 and 32x160), EH 100/230 hex 28x152, and EH 100/230 BR electric hammer configurations.
- Sustained Impact Resistance — Needle bearings in electric breakers absorb continuous reciprocating loads; a correctly specified bearing keeps percussion stroke energy focused and prevents premature wear on surrounding components.
- Electrical Safety Compliance — Using the correct OEM bearing in an electric demolition tool helps maintain the structural integrity of the drive assembly, supporting safe operation under rated load.
A needle bearing in an electric demolition breaker supports the reciprocating piston and chuck shaft, allowing smooth rotational and linear motion under the intense impact forces generated during breaking and chiseling. Because needle bearings carry high radial loads within a compact profile, they are critical to keeping the tool's drive mechanism aligned and efficient. When a needle bearing wears or fails, operators typically notice increased vibration, reduced impact force, or audible roughness in the tool's stroke — all signs that the bearing is no longer supporting the piston assembly correctly and that further internal damage is likely if operation continues.
