Wacker Neuson 5002001939 Retaining Ring

The Wacker Neuson is a genuine OEM Retaining Ring designed for a wide range of Wacker Neuson compaction and demolition equipment, including the RD10 and RD25 tandem rollers, DPU reversible vibratory plate compactors, and EH electric breaker series. As a factory-sourced component, the is manufactured to the exact tolerances and material specifications of the original part, ensuring a correct, secure fit within the assembly. This retaining ring spans an extensive compatibility list — covering DPU models from the DPU 4045H through the DPU 130Le and DPU 100-70, as well as EH electric breakers ranging from the EH 23 through the EH 75 series. When you need a dependable, like-for-like replacement backed by Wacker Neuson's OEM standards, the is the correct part to order.

Key Features

• OEM-Grade Retention Strength — Manufactured to Wacker Neuson's original material and dimensional spec, delivering the same grip force and fatigue resistance as the factory-installed ring.
• Direct Drop-In Fitment — Seats into the original groove without modification, maintaining correct axial positioning of the retained component across all compatible assemblies.
• Broad Cross-Family Compatibility — Fits RD10 and RD25 tandem rollers, DPU 4045H, DPU 5045H, DPU 6055, DPU 7060, DPU 9070, DPU 100-70, and DPU 130Le reversible vibratory plates, plus a wide range of EH electric breakers from EH 23 through EH 75.
• Prevents Axial Drift and Component Loss — A properly seated retaining ring locks rotating or sliding parts in place; a worn or missing ring allows axial movement that leads to accelerated wear, misalignment, or complete component separation.
• Critical Safety Function in High-Vibration Applications — In vibratory compaction and demolition equipment, retaining rings are exposed to sustained cyclic loads; the OEM specification ensures the ring will not fatigue or unseat under operating stress.

A retaining ring — also called a snap ring or circlip — is a fastening component that seats into a machined groove on a shaft or inside a bore to prevent axial movement of an adjacent part such as a bearing, gear, or bushing. In compaction and demolition equipment, these rings are subjected to constant vibration and impact forces, making material quality and dimensional accuracy critical to their service life. When a retaining ring fails, becomes deformed, or is lost during servicing, the component it was holding can shift, bind, or separate entirely, leading to secondary damage across the assembly.
