The Wacker Neuson 5100031553 Ball Bearing is a genuine OEM component designed for the PG1 Dewatering Pump. Sourced directly from Wacker Neuson, this is the exact same bearing specified for the machine at the point of manufacture — ensuring a true like-for-like replacement. If your PG1 is showing signs of shaft vibration, unusual noise, or bearing wear, replacing with part number 5100031553 restores the pump to its original operating condition.
Key Features
- Genuine OEM Tolerancing — Manufactured to the exact dimensional and load-rating specifications required for smooth, low-friction shaft rotation in the PG1 pump assembly.
- Drop-In Replacement — Matches the original bearing seat dimensions, so it installs directly into the existing housing without any rework or adaptation.
- Verified PG1 Fitment — Confirmed for the Wacker Neuson PG1 Dewatering Pump, giving you confidence you're ordering the correct part before it arrives on site.
- Sustained Pump Performance — A properly functioning ball bearing keeps the impeller shaft running true; a worn bearing causes vibration, heat build-up, and accelerated seal failure that can take the pump out of service entirely.
- Backed by Wacker Neuson — As a genuine OEM part, 5100031553 is held to the same quality standards as the original component, supporting the long-term integrity of your pump.
A ball bearing serves as the primary rotational support for the pump shaft, allowing the impeller to spin freely while absorbing both radial and axial loads generated during operation. In a dewatering pump like the PG1, the bearing is constantly exposed to mechanical stress and moisture-adjacent conditions, making its condition critical to uninterrupted flow performance. When a ball bearing begins to wear, the resulting play in the shaft leads to vibration, increased friction, elevated heat, and eventual damage to surrounding seals and the impeller itself — so prompt replacement with the correct OEM part is essential.
