The Wacker Neuson Plain Bearing is a genuine OEM component designed for the ML440, ML240, ML425, and ML225 series light towers and multifunction floodlight towers. Sourced directly from Wacker Neuson, this bearing meets the exact tolerancing and material specifications used in original production — so it seats and performs exactly as the factory intended. Compatible across a wide range of ML-series configurations, including RAW variants, the is the correct replacement when the original bearing shows wear, play, or noise.
Key Features
- OEM Precision Tolerancing — Manufactured to the exact bore and load specifications of the original bearing, ensuring consistent shaft alignment and smooth rotation under operating loads.
- Direct Drop-In Replacement — Matches the original mounting geometry of the ML-series mast and tower assemblies, allowing straightforward removal and installation without modification.
- Broad ML-Series Fitment — Compatible with ML440, ML240, ML425, and ML225 light towers and multifunction floodlight towers, including RAW variants across multiple production configurations.
- Sustained Tower Operation — A correctly functioning plain bearing keeps the mast rotating freely and smoothly; a worn bearing causes binding, uneven movement, and accelerated wear on surrounding components.
- Genuine Wacker Neuson Part — Supplied as authentic OEM stock, carrying the same part number (5000406509) referenced in Wacker Neuson service documentation for verified fitment accuracy.
A plain bearing provides a low-friction interface between two moving or rotating surfaces — in this case within the mast or pivot assembly of the light tower. Unlike rolling-element bearings, a plain bearing relies on a precisely machined surface and correct material composition to support load and allow smooth movement. When this bearing wears down or becomes damaged, the result is increased play in the mast assembly, binding during raising or lowering, and the potential for accelerated damage to the shaft and housing it supports. Replacing it promptly with the correct OEM part restores smooth, controlled tower operation.
