Wacker Neuson 5000218381 Ring Spacer

The Wacker Neuson Ring Spacer is a genuine OEM component designed for the IREN 57, IREN 58, IREN 65, IRFU 57, IRFU 58, IRFU 65, IRSEN 57, IRSEN 58, IRflex 58, and IRFU 60 series internal vibrators. Sourced directly from Wacker Neuson, this part carries the same manufacturing tolerances and material specifications as the original — ensuring it seats and functions exactly as intended. The covers an extensive range of internal vibrator configurations across multiple voltage and hose-length variants, making it a widely applicable service part for concrete consolidation equipment fleets.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original tolerance stack-up specs, so the spacer maintains correct axial clearance within the vibrator head assembly without shimming or adjustment.
• Direct Drop-In Installation — Matches the original mounting interface and ring profile, allowing straightforward disassembly and reassembly without machining or fitting work.
• Broad Series Coverage — A single part number that fits IREN 57, IREN 58, IREN 65, IRFU 57, IRFU 58, IRFU 65, IRSEN 57, IRSEN 58, IRflex 58, and IRFU 60 internal vibrator families across 115V, 120V, and 230V configurations.
• Correct Internal Geometry — Proper spacing between rotating and stationary components keeps vibration output consistent and prevents premature wear on adjacent bearings and shaft surfaces.
• Verified OEM Part Number — Part number 5000218381 is the authorised Wacker Neuson reference, eliminating guesswork when ordering service parts for mixed vibrator fleets.

A ring spacer is a precision-fit component positioned inside the vibrator head to maintain the correct axial gap between rotating internal parts. It ensures that spinning components run true and do not contact surrounding surfaces during operation, which is critical for consistent vibration frequency and amplitude in concrete consolidation work. When a ring spacer wears, cracks, or is installed incorrectly, it allows unwanted movement within the head assembly — leading to uneven vibration output, accelerated bearing wear, and eventual failure of the vibrator needle.
