The Wacker Neuson 5200019845 Bearing is a genuine OEM component designed for the APT4S and APT4T series submersible pump units, including cold weather, electric brake, and surge brake configurations. As a factory-sourced part, the 5200019845 meets the original engineering tolerances specified for these pumps, ensuring consistent fit and function across the full range of covered variants. This bearing is the correct replacement for both skid-mounted and standard APT4S models as well as all APT4T configurations, giving service technicians a single verified part number across the lineup.
Key Features
- OEM Precision Tolerancing — Manufactured to the exact dimensional and load-rating specifications of the original bearing, maintaining proper shaft alignment and rotational accuracy within the pump assembly.
- Direct Drop-In Replacement — Engineered to seat into the same bearing housing as the factory component, requiring no machining or fitment adjustment during installation.
- Broad APT4S and APT4T Compatibility — Verified fitment across APT4S Pump with Skid, APT4S Pump with Skid Cold Weather, APT4T Pump with Electric Brake, APT4T Pump with Surge Brake, and all corresponding cold weather variants.
- Sustained Pump Output — A correctly seated bearing keeps the pump shaft running true, protecting impeller efficiency and preventing premature wear on surrounding components caused by shaft deflection or play.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so you can confirm part number 5200019845 against your machine's parts manual with confidence.
A bearing in a submersible pump supports the rotating shaft, allowing it to spin freely while absorbing both radial and axial loads generated during pumping. When a bearing wears or fails, the shaft can develop unwanted movement, leading to vibration, increased friction, accelerated seal wear, and ultimately pump failure. Replacing a worn bearing promptly with the correct OEM part restores smooth rotation, protects the mechanical seal, and extends the overall service life of the pump.
