The Wacker Neuson is a genuine OEM Ball Bearing designed for the PS2-3703, PS3-3703, and PS4-3703 series submersible pumps. As a factory-sourced component, this bearing meets the original engineering tolerances specified for these pumps across a wide range of voltage configurations, including 220V, 440V, 575V, and 400V/50Hz variants. Confirm your model number against the fitment list before ordering to ensure correct application. Stocking a verified replacement like the keeps your pump rebuild on track without guesswork.
Key Features
- OEM-Spec Radial Tolerance: — Manufactured to the exact dimensional and load-rating specifications Wacker Neuson set for these submersible pump motors, ensuring proper shaft alignment and smooth rotation under load.
- Drop-In Replacement: — Matches the original bearing seat dimensions in the PS2-3703, PS3-3703, and PS4-3703 pump housings for a straightforward swap during motor service or rebuild.
- Broad Fitment Coverage: — Compatible with PS-series submersible pumps in 2-inch, 3-inch, and 4-inch discharge configurations across multiple voltage ratings (220V, 440V, 575V, and 400V/50Hz variants), including PSC20753 three-phase models.
- Sustained Motor Efficiency: — A correctly seated ball bearing allows the pump motor's rotor to spin freely at rated speed. A worn or failed bearing causes vibration, heat buildup, and motor failure — shortening pump service life significantly.
- Genuine Wacker Neuson Part: — Sourced directly from Wacker Neuson's OEM supply chain, so the part number, dimensions, and material grade match what was installed at the factory.
A ball bearing in a submersible pump supports the motor shaft radially, allowing the rotor to spin with minimal friction while handling the axial and radial loads generated during pumping. In a submersible application, the bearing operates in a sealed, water-adjacent environment where contamination and moisture ingress place extra demand on material quality and sealing integrity. When a bearing wears out, shaft runout increases, impeller clearances shift, and motor current draw rises — eventually leading to overheating or catastrophic motor failure. Replacing the bearing at the first sign of noise or vibration is the most cost-effective way to restore full pump output and protect the motor.
