The Wacker Neuson Spring Washer is a genuine OEM component designed for the AR 26, AR 36, and ARFU 36 series external vibrators. As a direct OEM part, it is manufactured to the same specification as the original, ensuring correct fit and consistent performance across the wide range of compatible models. This Spring Washer supports fastener integrity within the vibrator assembly, and using the correct OEM part helps maintain the reliability and service life of your equipment. Compatible models span multiple voltage configurations and regional variants within the AR and ARFU external vibrator families.
Key Features
- Genuine OEM Spring Tension Spec — Manufactured to the original load and deflection rating, ensuring the washer delivers the correct clamping force without over-compressing or losing tension under vibration.
- Direct Drop-In Replacement — Matches the original mounting profile and seat dimensions, fitting into the fastener stack exactly as the factory-installed part does with no rework needed.
- Broad AR and ARFU Series Coverage — Compatible with AR 26, AR 36, and ARFU 36 external vibrators across multiple voltage variants including 042V, 115V, 230V, 240V, 400V, and 480V configurations.
- Resists Loosening Under Continuous Vibration — A spring washer in a vibrating machine does constant work; the correct material grade and temper keep fasteners secure through sustained high-frequency operation.
- Sourced Direct from Wacker Neuson — Supplied as a genuine Wacker Neuson OEM part, backed by the manufacturer's parts program and carrying the correct part number 5000201286 for confident ordering.
A spring washer is a hardened, slightly domed or wave-formed washer placed under a fastener to maintain tension and resist loosening caused by vibration or thermal cycling. In an external concrete vibrator like the AR and ARFU series, components are subject to constant high-frequency movement, which can work fasteners loose over time — the spring washer acts as a mechanical lock, keeping joints tight and the assembly secure. When a spring washer flattens, cracks, or loses its temper, fasteners can back out, leading to play in the assembly, accelerated wear on surrounding components, and potential mechanical failure if left unaddressed.
