The Wacker Neuson 5100028519 is a genuine OEM Ball Bearing designed for the PS4-7503 and PS4-11003 series submersible pumps. As a factory-sourced component, it is manufactured to the exact tolerances required by the PS4 pump family, covering high-output and high-head configurations in both single-voltage and dual-voltage variants. Confirmed fitment spans PS4-7503HF, PS4-7503HH, PS4-11003HF, and PS4-11003HH models across 220V, 440V, and 400V configurations. Ordering by part number 5100028519 ensures you receive the correct bearing for your specific pump without guesswork.
Key Features
- Precision-Toleranced OEM Bearing — manufactured to the exact radial clearance and load rating specified for PS4-series submersible pump motors, ensuring correct shaft support under continuous submerged operation.
- Drop-In Replacement — dimensionally identical to the original bearing, seating directly into the motor housing with no shimming or modification to mounting surfaces.
- Broad PS4 Series Coverage — fits PS4-7503HF, PS4-7503HH, PS4-11003HF, and PS4-11003HH models across 220V/60Hz, 440V/60Hz, and 400V/50Hz electrical configurations.
- Protects Motor Shaft Alignment — a worn or failed bearing causes shaft runout, increased motor load, and accelerated seal wear; replacing it at the correct interval preserves pump efficiency and motor integrity.
- Genuine Wacker Neuson Part — sourced directly from Wacker Neuson, carrying the full OEM part number 5100028519 for straightforward verification against your machine's parts manual.
A ball bearing in a submersible pump motor supports the rotating shaft, allowing it to spin freely while absorbing both radial and axial loads generated during pumping operation. In a submerged environment, bearings are exposed to demanding conditions, and any degradation in the bearing's internal clearance or race surface causes vibration, increased current draw, and accelerated wear on surrounding seals and the motor winding. Catching and replacing a failing bearing early with the correct OEM-spec component keeps the motor running at its rated output and prevents a minor service item from escalating into full motor replacement.
