Wacker Neuson 5002003586 Internal Retaining Ring 20Mm X 1

The Wacker Neuson Internal Retaining Ring 20Mm X 1 is a genuine OEM component designed for the EH 23, EH 24, and EH 22 series electric breakers and demolition hammers. As a factory-sourced part, it is manufactured to the exact dimensional and material specifications required by Wacker Neuson for these machines. Compatibility spans a wide range of voltage configurations including 42V, 110V, 115V, 230V, 250V, and 400V variants across the EH 22, EH 23, and EH 24 series, as well as the EHL 22 and TEH 1 demolition set. Ordering by part number confirms you are getting the correct ring for your specific machine.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to exact 20mm internal diameter and 1mm groove width tolerances, ensuring the ring seats and retains under the dynamic loads produced by electric breaker mechanisms.
• Direct Drop-In Installation — Matches the original groove profile inside the tool housing, snapping into place without machining or modification to the bore.
• Broad Series Compatibility — Fits EH 22, EH 23, and EH 24 series electric breakers and demolition hammers across multiple voltage variants, plus the EHL 22/400 and TEH 1 demolition set.
• Maintains Internal Component Security — A correctly seated retaining ring keeps shafts, bearings, and internal assemblies properly located; a worn or missing ring allows axial movement that leads to accelerated wear across adjacent components.
• Sourced Directly from Wacker Neuson — Genuine OEM provenance means the material grade, hardness, and finish match the original part replaced during service or rebuild work.

An internal retaining ring is a precision-formed circlip that fits into a machined groove inside a bore or housing to prevent the axial movement of shafts, pins, bearings, or other internal components. In an electric breaker or demolition hammer, these rings work under repeated impact loads and vibration, holding critical drive components in their correct operating position. When a retaining ring becomes worn, distorted, or dislodged, the components it secures can shift out of alignment, causing uneven wear, noise, or mechanical failure that can propagate through the entire tool assembly.
