The Wacker Neuson 5200020004 Bearing is a genuine OEM component designed for the APT4S and APT4T pump series, including Cold Weather, Electric Brake, and Surge Brake configurations. As a direct factory replacement, this bearing is manufactured to the original tolerancing and load specifications required to keep these pump units running true. It fits across the full APT4S and APT4T family, covering both skid-mounted and trailer-mounted variants. Confirm your machine number against the fitment list to ensure this is the correct bearing for your specific unit before ordering.
Key Features
- Precision OEM Tolerancing — Manufactured to exact radial and axial load specs for the APT4S and APT4T pump assemblies, ensuring correct shaft alignment and smooth rotation under operating loads.
- Drop-In Replacement — Matches original mounting dimensions and bearing seat geometry, allowing installation without modification to housings or adjacent components.
- Broad APT4 Family Coverage — Verified fitment across APT4S Pump with Skid, APT4T Pump with Electric Brake, APT4T Pump with Surge Brake, and all Cold Weather variants within both series.
- Supports Consistent Pump Output — A worn or failed bearing can introduce shaft play, increasing vibration and causing premature seal and impeller wear; replacing it promptly restores smooth, stable pump operation.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5200020004 carries the same quality assurance as the bearing installed at the factory.
A bearing in a pump unit supports the rotating shaft, maintaining its centered position within the housing as the impeller spins under load. It absorbs both radial forces from the rotating assembly and any axial thrust generated during pumping, allowing the shaft to turn freely with minimal friction. When a bearing wears, it introduces unwanted movement into the shaft, which stresses seals, misaligns the impeller, and — if left unchecked — can lead to more extensive damage to the pump housing and drive components.
