The Wacker Neuson is a genuine OEM Cylinder Guide designed for the EH 100 series electric breakers, including EH 100/240 and EH 100/230 models across multiple chisel and hex configurations. As a factory-sourced component, the is manufactured to the exact tolerances required for consistent piston travel and impact alignment within the breaker's cylinder bore. Confirmed fitment spans the EH 100/230 28x152, 28x160, and 32x160 variants, as well as the EH 100/240 28x152 US configuration, making this a widely applicable part across the EH 100 family.
Key Features
- OEM-Grade Bore Tolerance — Manufactured to exact internal diameter specifications, ensuring the piston moves without play or misalignment through the full stroke cycle.
- Drop-In Cylinder Replacement — Engineered to match the original guide profile, seating directly into the cylinder housing without additional machining or shimming.
- Broad EH 100 Series Fitment — Compatible with EH 100/230 and EH 100/240 models in 28x152, 28x160, and 32x160 tool shank configurations, covering a wide range of jobsite breaker setups.
- Sustained Impact Accuracy — A correctly functioning cylinder guide keeps the striker centered and on-axis, delivering full energy transfer to the chisel on every blow; a worn guide causes lateral drift and reduced breaking force.
- Electrical Safety Compliance — As a genuine OEM part for an electric breaker, the 5000128423 maintains the structural integrity of the tool's internal impact assembly, preserving the alignment that protects surrounding electrical components from stress and vibration damage.
The cylinder guide is a precision sleeve housed inside the breaker's main body that controls the linear path of the striker or piston as it reciprocates during operation. It keeps the internal impact mechanism centered and aligned, ensuring that energy generated by the motor is transferred cleanly and directly to the chisel point rather than lost to side-loading or friction. When the cylinder guide wears or cracks, the piston begins to move off-axis, leading to reduced chiseling power, accelerated wear on surrounding components, and potential damage to the cylinder wall itself.
