Royal “Oil Country” Big-Bore Bull Head Live Centers
- Designed specifically for machining large diameter pipes for the oil and gas industry, but suitable for all large-bore applications.
- In contrast to standard bull head live centers, the modular head design of Royal “Oil Country” Big-Bore centers positions the workpiece closer to the bearing assembly for greater rigidity and longer operating life.
- Interchangeable heads are relieved to achieve the optimal strength/mass ratio, and are sized to cover a wider range of bore sizes with fewer models.
- Bearing configuration consisting of a heavy-duty tapered roller bearing, a large axial thrust bearing, and two precision needle bearings provides exceptional accuracy and rigidity under the most demanding production conditions.
