The Wacker Neuson 5200020253 Ball Bearing is a genuine OEM component designed for the APT4T and APT4S series submersible pumps. This includes APT4T Pump models with Electric Brake and Surge Brake configurations, as well as Cold Weather variants, and the APT4S Pump w/Skid and its Cold Weather counterpart. As a factory-sourced part, the 5200020253 is manufactured to the same tolerances and specifications as the original bearing installed at production, ensuring a direct, reliable fit within the pump assembly. Keep a replacement on hand to avoid unplanned interruptions during active dewatering operations.
Key Features
- OEM-Grade Precision Tolerancing — Manufactured to exact radial clearance and load-rating specs required by the APT4T and APT4S pump rotating assembly, ensuring smooth, consistent operation under continuous submersible duty.
- Drop-In Replacement — Matches the original bearing seat dimensions and fit, so the 5200020253 installs directly into the pump housing without modification to mounting surfaces or shaft interfaces.
- Broad APT Series Compatibility — Confirmed fitment across the full APT4T and APT4S families, covering Electric Brake, Surge Brake, and Cold Weather configurations.
- Protects Pump Shaft and Impeller Alignment — A worn or failed bearing allows shaft deflection, which leads to impeller contact with the pump housing, accelerated seal wear, and eventual motor damage.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, so you can be confident this is the correct part for your machine, not an approximation.
A ball bearing in a submersible pump supports the rotating shaft that drives the impeller, keeping it centered and allowing it to spin freely with minimal friction. In a submersible dewatering pump like the APT4T and APT4S, the bearing must withstand continuous rotational loads while operating in wet, demanding environments. When a bearing wears out, it causes vibration, shaft wobble, and excessive heat buildup — symptoms that quickly damage seals, the impeller, and the motor if left unaddressed. Replacing a failed bearing promptly with the correct OEM part restores proper shaft support and protects the surrounding components from secondary damage.
