The Wacker Neuson Spring Washer is a genuine OEM component designed for the AR 3/2 series external concrete vibrators, including AR 3/2 S, AR 3/2 W, AR 3/2 W/S, and AR 3/2 460V 60Hz variants. As a factory-sourced part, the is manufactured to the exact material and dimensional specifications required by the AR 3/2 family. This spring washer covers an extensive range of AR 3/2 machine numbers, making it the correct choice whether you are servicing a standard 400V unit or a 230/460V 60Hz configuration.
Key Features
- Genuine OEM Temper and Tension: — Manufactured to Wacker Neuson's specified spring rate, ensuring consistent clamping force and fastener retention across the AR 3/2 vibrator assembly.
- Direct-Fit Installation: — Matched to the correct bore diameter and thickness for AR 3/2 hardware interfaces, seating flush without modification.
- Broad AR 3/2 Series Coverage: — Confirmed fitment across AR 3/2 S, AR 3/2 W, AR 3/2 W/S, and AR 3/2 460V 60Hz external vibrator configurations spanning numerous machine numbers.
- Fastener Security Under Vibration: — Spring washers in external vibrators are subject to continuous cyclic loading; a properly spec'd washer prevents fastener backing-out and maintains structural integrity of the vibrator housing.
- Corrosion-Resistant Construction: — Built to withstand the wet, concrete-laden environments typical of formwork and precast concrete applications where AR series vibrators operate.
A spring washer functions as a locking and load-distributing element within a bolted fastener assembly. In an external concrete vibrator like the AR 3/2 series, the unit produces intense, continuous vibration that is transferred directly through the housing to formwork or molds — and that same vibration acts on every fastener holding the unit together. The spring washer maintains tension on the fastener, preventing it from loosening during operation. When a spring washer becomes flattened, cracked, or corroded, it loses its clamping function, allowing fasteners to work loose and potentially leading to housing separation, electrical exposure, or vibrator failure mid-pour.
