The Wacker Neuson Ball Bearing is a genuine OEM component designed for PS2, PSA2, PST2, PST3, PSTF2, PSTF3, PSG2, and PSR1 series submersible pumps. As a direct OEM part, the is manufactured to the same specification as the original bearing installed at the factory, ensuring a drop-in fit with no guesswork on tolerances or dimensions. This bearing spans a wide range of voltage configurations and pump capacities across the Wacker Neuson submersible pump lineup, making it a go-to service part for contractors and rental fleets maintaining multiple units.
Key Features
- OEM-Grade Bearing Tolerancing — Manufactured to the exact radial clearance and load rating specified for Wacker Neuson submersible pump motor shafts, maintaining smooth, low-friction rotation under continuous submerged operation.
- Direct Shaft Fit — Seats directly onto the pump motor shaft without shimming or adaptation, preserving correct rotor alignment and seal face contact.
- Broad Series Coverage — Compatible with PS2, PSA2, PST2, PST3, PSTF2, PSTF3, PSG2, and PSR1 submersible pump models across 110 V and 230 V configurations, covering a wide range of jobsite dewatering equipment.
- Protects Motor and Seal Integrity — A worn ball bearing allows shaft deflection that accelerates mechanical seal wear and can lead to water ingress into the motor housing; replacing it at the first sign of noise or heat prevents cascading damage.
- Genuine Wacker Neuson OEM Part — Sourced directly through authorized distribution channels, carrying the part number 5000150555 for straightforward parts verification and inventory tracking.
The ball bearing in a submersible pump supports the motor's rotating shaft, keeping it centered and allowing it to spin freely with minimal friction. In a submerged environment, this bearing endures constant load from the impeller and must resist moisture-related degradation — making correct specification critical. When the bearing wears, it creates shaft runout that strains the mechanical seal, generates excess heat, and can ultimately allow water to enter the motor windings, resulting in motor failure. Replacing the bearing at the first sign of roughness, noise, or vibration is one of the most cost-effective ways to extend the service life of the pump.
