The Wacker Neuson Radial Ball Bearing 6303 is a genuine OEM component designed for the A5000, L5000, M1500, and M2500 series internal concrete vibrators. As a direct factory replacement, this bearing maintains the precise rotational tolerances required for consistent vibrator head performance across both ISO and ANSI configurations. Wacker Neuson genuine OEM parts are manufactured to the same specifications as the original components, ensuring a direct drop-in fit with no guesswork on compatibility. Whether you are servicing an A1500 power unit, an H55 vibrator head, or an M2500 drive unit, part number is the correct bearing for the job.
Key Features
- Precision Radial Load Tolerance — The 6303-series ball bearing is rated for the radial load demands of high-frequency concrete vibrator spindles, maintaining smooth rotation under continuous duty cycles.
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this bearing meets original design tolerances for inner/outer race dimensions and ball complement — no dimensional guesswork.
- Broad Fitment Across Vibrator Families — Confirmed fit for A5000/160, A5000/160B, L5000/225, A1500/035, M1500/120, M1500/230, M2500/120, and M2500/230 units in both ISO and ANSI configurations.
- Restores Full Vibrator Head Output — A worn or failed radial bearing causes vibration loss, spindle wobble, and accelerated wear on surrounding components; replacing it with 5000078718 restores rated concrete consolidation performance.
- Direct Service Replacement — Installs in the same bearing seat as the original, requiring only standard bearing removal and installation tools — no housing modifications needed.
A radial ball bearing supports the rotating shaft inside a concrete vibrator's power unit or vibrator head, allowing it to spin at high frequency with minimal friction. It carries the radial loads generated during operation and keeps the shaft centered within its housing. When this bearing wears out, operators typically notice increased heat at the housing, audible grinding, reduced vibration amplitude at the head, or complete seizure of the spindle — all of which compromise concrete consolidation and risk damage to connected components. Replacing the bearing promptly with the correct OEM part restores the full rotational efficiency the unit was designed to deliver.
