The Wacker Neuson 5200021628 is a genuine OEM Bearing Spacer designed for the APT6S and APT6T series self-priming pumps. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory, ensuring a correct fit within the pump's bearing assembly. It is compatible across the APT6S and APT6T lineup, including skid-mounted, electric brake, surge brake, and cold weather configurations. When bearing components wear or shift out of position, precise spacing is critical to maintaining proper load distribution and shaft alignment — making this a key service part to have on hand.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact thickness and bore tolerances required to maintain correct bearing preload and shaft alignment in the APT6S and APT6T pump assemblies.
- Direct-Fit Replacement — Drops into the existing bearing housing without machining or shimming, preserving correct axial positioning of the bearing stack.
- Broad APT6 Series Coverage — Compatible with APT6S Pump with Skid, APT6T Pump with Electric Brake, APT6T Pump with Surge Brake, and all corresponding Cold Weather variants.
- Protects Bearing Service Life — Correct spacing prevents bearing misalignment and uneven wear, helping the pump maintain smooth impeller rotation and consistent flow output over time.
- Genuine Wacker Neuson Part — Part number 5200021628 is the manufacturer-designated replacement, eliminating guesswork when ordering for scheduled maintenance or repair.
A bearing spacer is a precision-machined ring or sleeve positioned between bearings or between a bearing and an adjacent component to control axial clearance and load distribution along a shaft. In a pump assembly, maintaining the correct spacing ensures the impeller shaft runs true, reducing vibration and preventing premature bearing failure. When a bearing spacer wears, corrodes, or is incorrectly sized, it can cause bearing misalignment, increased shaft play, and accelerated wear throughout the rotating assembly — ultimately leading to pump inefficiency or failure.
