The Wacker Neuson 5200019843 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 a precise, drop-in installation with no guesswork. It is confirmed compatible across the APT4S Pump w/Skid, APT4S Pump w/Skid Cold Weather, APT4T Pump Electric Brake, APT4T Pump Electric Brake Cold Weather, APT4T Pump Surge Brake, and APT4T Pump Surge Brake Cold Weather configurations. Sourcing a genuine Wacker Neuson part means you get the correct tolerancing and fitment your pump demands to stay running at full performance.
Key Features
- OEM Precision Tolerancing — Manufactured to exact dimensional specifications for the APT4S and APT4T pump families, ensuring correct load distribution and smooth rotation under working conditions.
- Direct Drop-In Installation — Matches the original bearing's seat dimensions and interface, so it installs directly into the pump housing without machining or adaptation.
- Broad APT4 Series Coverage — Fits six distinct APT4S and APT4T configurations, including standard, electric brake, surge brake, and cold weather variants.
- Sustained Pump Output — A correctly seated bearing keeps the pump shaft aligned and running true, maintaining consistent flow rate and discharge pressure across the full operating cycle.
- Genuine Wacker Neuson Part — Part number 5200019843 is sourced directly from Wacker Neuson, so you can verify fitment against your machine's serial number and parts documentation with confidence.
A bearing in a centrifugal pump supports the rotating shaft that drives the impeller, allowing it to spin freely while absorbing both radial and axial loads generated during pumping. When the bearing is in good condition, the shaft stays centered and the impeller operates at its designed clearance, delivering consistent water movement and pressure. As a bearing wears, it introduces shaft play that can cause impeller contact, increased vibration, seal failure, and ultimately pump shutdown — making timely replacement critical to keeping the pump serviceable.
