The Wacker Neuson 5100028570 is a genuine OEM Ball Bearing designed for the PS4-11003HF and PS4-11003HH submersible pump series. As a direct factory replacement, this bearing is built to the original geometry and load tolerances required by these high-output, high-head pump models. Whether you're servicing a 220V, 440V, or 400V configuration, part number 5100028570 is the correct specification for your PS4 pump. Keeping the bearing in good condition is essential to smooth shaft rotation and long pump service life.
Key Features
- Precision Load Rating: — Engineered to handle the radial and axial loads generated by PS4 submersible pump impeller shafts, maintaining consistent rotational accuracy under continuous submerged operation.
- Genuine OEM Sourcing: — Sourced directly from Wacker Neuson, this bearing matches the original dimensions and internal clearance specifications — no guesswork on sizing or fit.
- Broad PS4 Series Coverage: — Fits PS4-11003HF and PS4-11003HH pump models across multiple voltage configurations, including 220V/60Hz, 440V/60Hz, and 400V/50Hz variants in both High Head and High Output formats.
- Protects Pump Shaft and Housing: — A worn or failed bearing causes shaft wobble, accelerated seal wear, and eventual motor damage. Replacing with the correct 5100028570 bearing restores proper alignment and protects surrounding components.
- Direct Service Replacement: — Drops into the bearing seat as specified in the Wacker Neuson service documentation, making it a straightforward swap during scheduled pump maintenance or breakdown repair.
A ball bearing in a submersible pump supports the rotating impeller shaft, keeping it centered and allowing it to spin freely with minimal friction inside the motor housing. In a high-horsepower pump like the PS4-11003 series — which operates continuously while submerged — the bearing is under constant load, and any degradation in its condition directly affects pumping efficiency and motor temperature. When a bearing wears out, it typically produces audible noise, causes vibration, and — if left unaddressed — leads to shaft damage or seal failure that can take the entire pump out of service.
