The Honda 91051-ZB3-003 Bearing Assembly (6203) is a genuine OEM component designed for a wide range of Honda generators, including the EB2200, EB2500, EG1400, EG2200, EG2500, EM1600, EM1800, EM2200, EM2500, and EX2200. As a direct Honda OEM part, this bearing assembly is manufactured to the same specification as the original installed at the factory, giving you confidence in the fit and function. Honda generators span both conventional and inverter designs across this fitment range, so confirm your model and serial number against the fitment table before ordering to ensure this is the correct variant for your unit.
Key Features
- Genuine Honda OEM Quality — manufactured to the same specification as the original bearing, ensuring smooth rotational operation and consistent performance in the alternator assembly
- Direct OEM Replacement — engineered to install in place of the original bearing without modification, maintaining correct shaft alignment and running clearance
- Broad Generator Fitment — listed for Honda EB2200, EB2500, EG1400, EG2200, EG2500, EM1600, EM1800, EM2200, EM2500, and EX2200 generators; verify your serial number against the fitment table, as Honda supersedes parts at serial breaks
- Bearing Wear Prevention — a worn or failed bearing causes increased vibration, noise, and heat buildup that can lead to alternator shaft damage; replacing this component at the first sign of wear protects the surrounding assembly
A bearing assembly in a Honda generator supports and guides the rotation of the alternator shaft, allowing it to spin freely with minimal friction. The 6203 designation identifies the bearing's dimensional series, making it a specific, non-interchangeable component within the generator's rotating assembly. When a bearing wears, the resulting friction and play can cause shaft wobble, audible grinding or rumbling, excessive heat, and ultimately alternator failure — making timely replacement essential to keeping the generator producing clean, stable power output.
