The Honda 91056-VF9-B01 Radial Ball Bearing (6000Z) is a genuine OEM component designed for UMK422 and UMK431 trimmers. As a direct Honda OEM part, it meets the same specifications as the original bearing fitted at the factory, ensuring a proper service replacement. Honda supersedes parts at serial number breaks, so confirm your trimmer's serial number against the fitment table before ordering to ensure you receive the correct bearing for your unit.
Key Features
- Genuine OEM Bearing Grade — a Honda OEM radial ball bearing delivers the smooth rotation and dimensional accuracy that a trimmer's spinning components demand, unlike a generic substitute with unknown tolerances
- 6000Z Specification — the (6000Z) designation identifies the exact bearing series and shielding configuration; matching this specification to your unit is essential for correct fitment and operation
- Direct OEM Replacement — sourced directly from Honda and listed for UMK422 and UMK431 trimmers; verify your serial number against the fitment table to confirm this is the right bearing for your machine
- Restore Smooth Operation — a worn or seized ball bearing causes excessive vibration, noise, and heat buildup in rotating assemblies; replacing it with this genuine part restores quiet, smooth running
A radial ball bearing supports a rotating shaft and absorbs the radial loads generated as it spins, keeping the shaft centered and allowing it to turn freely with minimal friction. In a trimmer such as the UMK422 and UMK431, ball bearings are used at key points in the drivetrain to support the rotating shaft that transfers power from the engine to the cutting head. When a bearing wears out, it can develop play, generate heat, and cause vibration or noise — and if left unchecked, a failed bearing can damage surrounding components and put the entire unit out of service.
