The Wacker Neuson 5200019844 Bearing is a genuine OEM component designed for the APT4S and APT4T series self-priming pumps, including cold weather, electric brake, and surge brake configurations. As a direct factory replacement, this bearing is held to the same precision tolerancing as the original, ensuring the rotating assembly runs true and within specification. It fits the full range of APT4S and APT4T variants, making it a reliable solution whether you're servicing a standard pump or a cold-weather-equipped unit.
Key Features
- OEM Precision Tolerancing — Manufactured to exact dimensional and load-rating specs for the APT4S and APT4T pump families, ensuring the rotating assembly operates within design clearances.
- Drop-In Replacement — Engineered to seat identically to the original bearing, allowing straightforward installation without machining or shimming.
- Broad APT4 Series Coverage — Fits APT4S (standard and cold weather) and APT4T (electric brake, surge brake, and cold weather) pump configurations.
- Sustained Pump Output — A correctly seated bearing keeps the impeller shaft aligned and rotating freely, maintaining consistent flow and pressure; a worn bearing causes vibration, increased wear, and eventual shaft or seal failure.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5200019844 carries the same quality assurance as the bearing installed at the factory.
A bearing in a self-priming pump supports the rotating shaft that drives the impeller, keeping it centered and allowing it to spin freely under load. It absorbs both radial and axial forces generated during pump operation, protecting the shaft, seals, and impeller from misalignment-related wear. When a bearing wears or fails, it typically produces audible grinding or vibration, accelerates seal degradation, and can ultimately lead to shaft damage or a complete loss of pump function if left unaddressed.
