Bearing Bush 207 974 08 – What Is It?
The Bearing Bush 207 974 08 is a vital internal part of the rock drill assembly. It is manufactured from steel and positioned inside the central body of the drill. The bush is designed with lubrication channels that allow continuous oil circulation, reducing friction and wear. By supporting the internal shaft and guiding its movement, this component ensures smooth drilling performance and extends the overall lifespan of the machine.
Key Functions & Benefits
- Structural support: Provides a bearing surface between the central shaft and the housing.
- Durable steel construction: Withstands high mechanical loads and abrasive conditions.
- Lubrication grooves: Built-in oil channels deliver constant lubrication to critical parts.
- Enhanced drilling efficiency: Stabilizes internal movement, reducing vibration and wear.
- Longer machine life: Protects surrounding components from damage.
Where It’s Installed
The bearing bush is located inside the middle section of the rock drill, ensuring reliable performance of the piston and other moving parts during heavy-duty drilling.
