The Wacker Neuson Rear Bearing is a genuine OEM component designed for G50, G70, and G85 series skid-mounted mobile generators, as well as LTW20Z1 and LTW20Z3 series light towers. Sourced directly through Wacker Neuson's authorized parts supply chain, part meets the same tolerancing and material standards as the bearing installed at the factory. Compatibility spans a wide range of configurations including standard, cold weather, extended run tank, and custom variants across multiple emission tiers, so you can order with confidence regardless of your specific machine spec.
Key Features
- OEM-Grade Precision Tolerancing — Manufactured to exact radial and axial load specifications for the rear bearing position, ensuring consistent rotational accuracy under generator operating loads.
- Drop-In Rear Position Fitment — Engineered to seat correctly in the rear bearing housing without re-machining or shimming, maintaining proper shaft alignment on installation.
- Broad Model Coverage — Compatible with G50, G70, and G85 mobile generators and LTW20Z1 and LTW20Z3 light towers across standard, cold weather, custom, and extended run configurations.
- Sustained Alternator Output Stability — A correctly seated rear bearing holds the rotor in precise alignment, enabling steady power generation; a worn bearing introduces vibration and can lead to premature alternator failure.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM replacement under part number 5000183344, ensuring the component matches the original design intent for your machine.
The rear bearing supports the drive-end or non-drive-end shaft of the generator's alternator assembly, allowing the rotor to spin freely within the stator while carrying both radial and axial loads generated during operation. It acts as the critical interface between the rotating shaft and the stationary housing, keeping the rotor centered and preventing metal-to-metal contact. When this bearing wears or fails, operators typically notice increasing vibration, rising operating temperatures, unusual noise from the alternator end, and eventually a loss of output voltage as rotor alignment degrades.
