- OEM Number
- HD712-02350
- Compatible Brand
- Furukawa
- Part Type
- Drifter
What the PLAIN BEARING does
Bearings carry the rotation loads in the drifter's rotation gear and in the feed and boom assemblies. On a percussion machine they take a duty most bearings never see: steady rotational load with an impact pulse superimposed on it thousands of times a minute.
Signs it needs replacing
- Rumble, growl or a rising whine from the rotation housing
- Detectable radial or axial play in the rotation shaft
- Local heat at the bearing housing after a short run
- Metallic glitter in the drained oil
Before you fit it
Fit bearings clean, square and to the correct preload — most premature failures are fitting damage, not manufacturing defects. Replace the shaft seals at the same time; a bearing that failed because water reached it will fail again if the seal is reused.
General guidance for this class of component. Always work to the torque figures, clearances and service intervals in your machine's own manual.
