The Wacker Neuson 5100004449 is a genuine OEM Grooved Ball Bearing designed for the AR 26 series external concrete vibrators, including the ARFU26/6/120 US, ARFU26/6/115 UK, ARFU26/6/230, AR 26/6/042, AR 26/3,6/230, AR 26/3/400, AR 26/6/250, AR 26/3/230 w, AR 26/3,6/120 w, and AR 26/6/042 3,5kN models. As a direct Wacker Neuson OEM component, part 5100004449 is manufactured to the same tolerances as the original bearing installed at the factory, ensuring a correct drop-in fit without guesswork. This bearing is a critical rotating element inside the vibrator motor assembly and should be replaced at the first sign of heat buildup, noise, or loss of vibration output to prevent further damage to the unit.
Key Features
- OEM-Spec Radial Tolerancing — Manufactured to the exact groove geometry and internal clearance spec of the original bearing, maintaining correct load distribution within the AR 26 vibrator motor.
- Direct Drop-In Fit — Matches the original bearing seat dimensions inside the AR 26 series motor housing, allowing straightforward installation with standard bearing press tooling.
- Broad AR 26 Series Coverage — Compatible with a wide range of AR 26 external vibrator variants, including US, UK, and continental voltage configurations across single- and three-phase models.
- Sustained Vibration Output — A correctly seated grooved ball bearing keeps the eccentric rotor spinning true at rated frequency; a worn bearing causes irregular vibration, increased heat, and accelerated winding damage.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this bearing carries the same part number used in original production, giving you confidence in origin and material grade.
The grooved ball bearing in an external concrete vibrator supports the rotating eccentric shaft that generates the high-frequency vibration transferred through the vibrator head to the concrete form or mold. It must handle continuous radial loads at elevated speeds while resisting the heat generated during prolonged operation. When this bearing wears, it allows shaft play that disrupts vibration consistency, increases current draw on the motor windings, and can lead to premature motor failure if left unaddressed.
