The Wacker Neuson Rotary Shaft Seal is a genuine OEM component designed for the EH 100 series electric breakers and electric hammers, including multiple hex and bore configurations across the EH 100/230 and EH 100/240 model lines. As a factory-sourced part, the meets the original design tolerances for material grade and compression characteristics — critical qualities for a seal operating under the rotational loads and environmental exposure typical of breaker applications. Verified fitment spans several EH 100 variants, so confirm your specific model number before ordering to ensure you receive the correct seal for your machine.
Key Features
- OEM-Grade Seal Material — Manufactured to Wacker Neuson's original compound and compression specifications, delivering the lip durability and radial load resistance this application demands.
- Drop-In Replacement — Dimensioned to seat directly in the original housing bore, matching the shaft interface geometry of the EH 100 series without rework or shimming.
- Broad EH 100 Series Coverage — Fits EH 100/230 and EH 100/240 electric breakers and electric hammers across hex 28x152, 28x160, and 32x160 shaft configurations.
- Prevents Lubricant Loss and Contamination Ingress — A functioning rotary shaft seal keeps internal grease or oil where it belongs and blocks dust, water, and debris from reaching bearing surfaces — two failure modes that accelerate internal wear rapidly when the seal is compromised.
- Protects Drive Components Under Sustained Impact Load — Electric breakers operate under continuous percussive stress; maintaining a sound shaft seal is essential to protecting the gear and piston assembly from premature failure caused by dry running or contaminated lubrication.
A rotary shaft seal forms a dynamic barrier between a rotating shaft and its surrounding housing, keeping lubricant inside the mechanism while preventing outside contaminants from entering. In an electric breaker like the EH 100, the seal works against constant vibration and rotational movement, making material integrity and correct fitment especially important. When a shaft seal wears or fails, lubricant escapes, contaminants reach internal components, and the resulting friction and abrasion can quickly escalate into costly damage to the piston, crankshaft, or bearings.
