The Wacker Neuson Ball Bearing is a genuine OEM component designed for the PS2 and PS3 series submersible pumps. As an authorized Wacker Neuson part, the is manufactured to the same specification as the original, ensuring a direct, correct-fit replacement within the pump's rotating assembly. This bearing covers an extensive range of PS2 and PS3 models across multiple voltage configurations — including 220V, 400V, 440V, and 575V variants — making it the go-to service part for contractors and rental fleets running these pumps. Confirm your model number against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact bore, outer diameter, and load-rating specifications required by Wacker Neuson PS-series pump motors, ensuring the rotating shaft seats and spins correctly without play or premature wear.
- Drop-In Replacement for PS2 and PS3 Families — Fits a wide range of PS21503, PS22203, PS31500, PS31503, PS32200, PS32203, PSA21503L, PSA22203L, PS21503L, PS22203L, and PS31503L models across both 50Hz and 60Hz power configurations.
- Supports Full Pump Flow and Pressure Output — A worn or failed bearing causes shaft vibration, increased motor load, and eventual pump seizure; replacing it promptly restores smooth impeller rotation and rated discharge performance.
- Multi-Voltage Model Coverage — A single part number spans 220V, 400V, 440V, and 575V pump variants, simplifying parts stocking for service shops and rental fleets managing mixed-voltage equipment.
- Protects Motor Integrity — Bearing failure in a submersible pump allows the shaft to run off-center, accelerating seal wear and increasing the risk of water ingress into the motor housing; timely replacement safeguards the motor winding investment.
A ball bearing in a submersible pump supports the motor shaft and allows it to spin freely with minimal friction, maintaining precise alignment between the motor and impeller. When the bearing is in good condition, the pump moves water efficiently at its rated flow and head pressure. As the bearing wears, it introduces shaft wobble that strains the motor windings, accelerates mechanical seal degradation, and can ultimately cause the pump to seize — turning a simple bearing replacement into a far more costly motor rebuild or full unit replacement.
