The Wacker Neuson Rear Bearing is a genuine OEM rear bearing designed for the G25 Generator series, covering Standard, Cold Weather, Custom, Extended Run, Battlefield, and Mobile Generator configurations across T4, T4F, and T4i emission tiers. As a factory-sourced component, this part meets the original design tolerances specified for G25 generator applications, ensuring consistent fit and function across the full model range. Whether you're servicing a skid-mounted unit, an extended run tank configuration, or a URI HVAC variant, part number is the correct OEM replacement to restore your generator to proper operating condition.
Key Features
- OEM-Grade Precision Tolerancing — Manufactured to the exact dimensional and load-rating specifications of the original bearing, maintaining proper shaft alignment and rotational accuracy in the G25 generator.
- Direct Rear-Position Replacement — Seats into the rear bearing housing exactly as the original, requiring no modification to the end bracket or rotor shaft during installation.
- Broad G25 Series Coverage — Fits Standard, Cold Weather, Custom, Extended Run, Battlefield, Mobile, and URI HVAC variants across T4, T4F, and T4i model families.
- Sustained Output Stability — A correctly functioning rear bearing keeps the rotor centered and spinning true; a worn bearing causes vibration, increased heat buildup, and accelerating damage to the alternator windings.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, so you get the same component installed at the factory — not an approximation of it.
The rear bearing in a generator supports the non-drive end of the rotor shaft, allowing it to spin freely within the alternator housing while keeping it precisely centered relative to the stator. It carries both radial and axial loads generated during operation, and its condition directly affects how smoothly and quietly the generator runs. When the rear bearing wears, you may notice increased vibration, unusual noise from the alternator end, or rising operating temperatures — all signs that the bearing is no longer holding the rotor in proper alignment. Left unaddressed, a failed rear bearing can lead to rotor-to-stator contact and significant alternator damage, making timely replacement with the correct OEM part essential to protecting the rest of the machine.
