The Wacker Neuson 5200021801 Bearing is a genuine OEM component designed for the APT8T and APT8S pump series, including surge brake, electric brake, and cold weather configurations. Sourced directly from Wacker Neuson, this bearing meets the exact tolerancing and load specifications required for proper pump operation. Compatible models include the APT8T Pump with Surge Brake, APT8T Pump with Electric Brake, APT8S Pump with Skid, and their corresponding cold weather variants. Using the correct OEM part ensures the bearing seats and operates precisely as the machine was engineered to perform.
Key Features
- OEM-Spec Load Tolerancing — Manufactured to the exact dimensional and load-bearing specifications Wacker Neuson requires for this pump application, ensuring consistent performance under operational stress.
- Direct Drop-In Fit — Engineered to seat in the same position and orientation as the original, with no reworking of the bearing housing or shaft required.
- Broad APT8 Series Coverage — Fits APT8T and APT8S pump models across surge brake, electric brake, and cold weather variants, making this a single solution for the full APT8 lineup.
- Supports Smooth Pump Operation — A correctly functioning bearing maintains proper shaft alignment and rotation; a worn bearing can introduce vibration, heat buildup, and accelerated wear on surrounding pump components.
- Genuine Wacker Neuson OEM Part — Carries the part number 5200021801 as issued by Wacker Neuson, so you can verify fitment against your machine's parts manual with confidence.
A bearing in a pump assembly supports the rotating shaft, allowing it to spin freely while maintaining precise alignment under both radial and axial load. In the APT8T and APT8S pump series, the bearing plays a critical role in keeping the pump shaft stable during operation, which directly affects flow consistency and the longevity of seals and other rotating components. When a bearing wears or fails, it can cause shaft wobble, increased friction, heat generation, and eventual damage to adjacent parts — making timely replacement essential to keeping the pump running correctly.
