The Wacker Neuson 5200019836 Bearing is a genuine OEM component designed for APT4S and APT4T series self-priming centrifugal pumps. As a direct OEM replacement, this bearing is manufactured to the same specifications as the original, ensuring proper fit and function across the full range of APT4S and APT4T configurations — including Cold Weather, Electric Brake, and Surge Brake variants. Sourcing a genuine Wacker Neuson 5200019836 means you get a part that installs exactly like the factory original with no guesswork on compatibility. Keep your pump operating at peak capacity with a bearing built to handle the demands of continuous pumping cycles.
Key Features
- Precision-Grade OEM Construction — Manufactured to exact tolerancing for smooth, low-friction rotation — critical in a pump bearing subject to continuous radial and axial load during operation.
- Drop-In Replacement — Engineered to the same dimensional specifications as the original, seating directly into the pump housing without rework or shimming.
- Broad APT Series Compatibility — Fits APT4S Pump with Skid, APT4S Cold Weather, APT4T Electric Brake, APT4T Surge Brake, and their Cold Weather counterparts — one part number covers the full APT4 lineup.
- Protects Pump Shaft Integrity — A correctly functioning bearing maintains proper shaft alignment within the pump housing; a worn bearing allows shaft deflection that accelerates seal wear and can damage the impeller.
- Genuine Wacker Neuson Part — Supplied as an authorized OEM component, backed by Wacker Neuson's parts program for traceability and quality assurance.
A pump bearing supports the rotating shaft that drives the impeller, maintaining precise alignment while absorbing the radial and axial forces generated during pumping. When the bearing is in good condition, the shaft spins smoothly and concentrically, allowing the impeller to move water efficiently without placing undue stress on surrounding seals and housings. When a bearing wears or fails, shaft runout increases, leading to seal leakage, vibration, accelerated wear on adjacent components, and ultimately pump shutdown — making timely bearing replacement one of the most cost-effective maintenance steps on any centrifugal pump.
