The Wacker Neuson 5100018280 Bush is a genuine OEM component designed for the FUflex4 series internal concrete vibrators, including the FUflex4/230, FUflex4/120 (120 V), FUflex4/230 CH, and FUflex4/120 US variants. As a direct OEM part sourced through authorized Wacker Neuson supply channels, the 5100018280 meets the original design tolerances specified for this vibrator family.

Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the original bore and outer-diameter tolerances required for correct seating and alignment within the FUflex4 drive assembly.
- Drop-In Replacement — Engineered to install directly in place of the worn or damaged bush without machining or rework to the housing.
- Broad FUflex4 Series Coverage — Confirmed fit across FUflex4/230, FUflex4/120 (120 V), FUflex4/230 CH, and FUflex4/120 US internal vibrator models.
- Vibration Integrity Restored — A worn bush allows shaft play that disrupts the consistent eccentric motion concrete vibrators depend on; replacing it restores smooth, controlled vibration output.
- Verified Part Number — Part number 5100018280 is the OEM reference for this bush across all listed FUflex4 configurations, reducing the risk of ordering an incorrect component.
The bush in a FUflex4 internal concrete vibrator serves as a precision bearing surface that supports and guides the rotating shaft inside the vibrator head housing. It absorbs radial loads generated by the high-speed eccentric rotation that produces the vibration needed to consolidate concrete and eliminate air pockets. When the bush wears, the shaft develops excessive play, causing uneven vibration, accelerated wear to surrounding components, and ultimately a loss of consolidation effectiveness at the needle head.
